Superb III Sportline - Mission Impossible Spec

[ApertureS]

Today was a busy day, Im trying to cut down the work required for the largest part of the job so when I have time im undertaking the bits that can be done beforehand.

 

This first meant the roof lining coming down as photoed

 

This was to allow the NS antenna to be replaced from DAB to DAB/TV and its associated fakra cable running to the OS ready for routing to the TV tuner.

The OS antenna didnt exist, neither did its wiring so a quick loom was made up in the factory black/blue colours and the antenna and its 2 fakra cables for TV and Webasto antenna were ran down the OS D pillar.

The shark fin was replaced from GPS to GPS/Cellular - this new fakra cable was ran to the NS of the vehicle to meet up with the 2-way amplifer.

 

 

After this, it was the perfect time to run the wires needed into the trunk:

The first was the HSD connector which will end up connecting to the 360 camera system, this has been ran into the tailgate and cable tied out the way for now, the other end went down the OS D pillar with a male connector ready for a connection to run to the front of the car.

The second was the final antenna at the top of the tailgate, this was FM2, it is now FM2/TV and needed the fakra cable running to the same as above, into the car, down the D pillar and now has a male connector to allow full disconnecting of the tailgate if it ever needed to be fully removed.

 

 

Sadly to the keen eyed - the double fakra connectors are near impossible to source in anything except water blue/universal. The mustard, black and green ones are impossible to find in a one off quantity but as there are no other fakra connectors in the area, there is no risk of them being misconnected.

 

Everything was then refitted and tested for any rattles or such, no new sounds and 6 new data wires ran to the lower sections of the car, hopefully the headliner is never to come out again!

This weekends work may span 2 posts....

 

So the plan for this weekend was:

-Run the rear to front wiring

-Fit rear modules

-Fit TV tuner module

-Fit fuel lines

-Fit webasto fuel pump

 

So lets get started! Weather: Odd spots of rain but very very windy - meant no gazebo and had to work outside in the cold wind.

 

 

The rear modules we had to fit were the 2-way amplifier for the signal booster, the DCC module and the webasto remote start control module. All part numbers on show for anyone that needs them. The fakra connectors for the remote start and 2-way were terminated and connected. The 2-way fakra was connected and ran down the nearside of the car towards the front.

 

Next up the webasto fuel pump and fuel lines were fitted - the fuel pump and lines vary by petrol/diesel/hybrid and FWD/AWD so my part numbers are for petrol FWD.

Pump 3Q0201607                   Fuel lines 3Q0200059BF

Officially you are meant to drop the tank slightly to fit the pump but I managed to run it up and over the tank without dropping it. Once on top of the tank, cut the small blue nipple off and fit and crimp the rubber fitting.

The fuel lines, although they seem daunting, they were incredibly simple to fit, disconnect at the rear of the car and remove the plastic retainer, then pull them off their bracket at the front and all 2/3 fuel lines slide out the front as one. Reverse for fitting.

(Note - the front fuel line connector is a PITA - to release it, you need to push it inwards till its flush, then press the tiny black tabs in on either side and slide it off, dont use force or tools, youll break it!)

The wiring was also ran through the waterproof connector and terminated.

 

 

Whilst the rear of the car interior and the underside was partially stripped, the rear arch wiring was ran - again this has a few options depending on FWD/AWD but for FWD the part numbers are as follows 3G0927902B and 3G0927902K. The only difference for these were the DCC connectors and as much as I could run my own DCC wires and connectors, I want it as OE as possible. These come through grommets in the rear footwell area and run to wires running just under the front edge of the rear bench.

The DCC connectors were waterproofed and cable tied up for now. I was also missing the small plastic brackets that hold the wires to the top arms, these have also been ordered (5Q0614167B)

 

 

The rear DCC sensor was fitted just below the NS seat belt - A threaded insert was fitted and the DCC sensor fitted - this sensor needs to be pointing forward with 10 degrees of accurary.

Continued:

 

The TV tuner was next to fit - this is a bit more complicated than just fitting as the place under the OSF seat for the tv tuner is also where the 360 camera module is fitted - so to work around this, The plan is to cut the carpet under the TV tuner and mount the 360 module under the TV tuner, Ill possibly use some thermal paste/pad against the floorpan to prevent any possible overheating.

The TV tuner bracket is fitted with 2x M6 nuts and a hexagonal threaded insert with a 10mm bolt.  TV tuner slid into place and the cover was then fitted with 2x pop rivets.

 

 

 

Now for the spaghetti that is wiring.... A conservative guess for the wiring fitted this weekend was around 250 meters, so just a little bit....

Wiring was ran from the boot area from all modules, the tailgate, the rear antennas, the rear arch wiring and then this all needed to make its way forward down the left and right side of the car.

The factory looms were stripped of their original wraps and the new wires bound tightly within. The loom wrapping stopped inline with the front seats and the wires tucked behind the A pillars behind the dash. The aim here was for the wires to look factory, fit perfectly and not have any chafing issues. A range of fixings were purchased just in case the original loom fixings broke, out of all of them, only 1 clip broke. 

 

To start - some photos of the messy wiring! The majority is ran down the offisde and then it transfers to the nearside front corner behind the dashboard. The nearside had around 5 wires compared to the 50 or so on the offside.

 

 

Now some photos of neatly wrapped wires that would you believe it, contain all them wires in the photo above plus the original wires. I think I used roughly 3x 25 meter rolls of loom tape (varying widths and abrasion resistance depending on the areas).

 

 

 

 

 

Now that was a productive weekend! Got a few more snags to sort out tomorrow morning but then i think I'm due a beer and to rest my back.

Are you an electrician?

 

Either way, you certainly are a master at wiring things in - I'm amazed by the amount of time and effort you've spent so far! Well done 😲

The wires themselves depends on what wire im after.

 

For the standard dual colour wires in 0.35mm to 6.0mm the best supplier ive found is ALMsolutions. They offer most colours in most sizes with 1.0mm being the most common it has the most options. The 0.5mm has a huge amount of options too and seen as im yet to find a supplier offering the 0.35mm wire in dual colour for less than 100M per order, ive had to use 0.5mm in place of the 0.35mm in most places. The most common size for the general wiring is 0.35mm or 0.5mm

 

For the fakra, BEVOTOP seems to be a good aliexpress supplier as ive had no issues with their connectors and wires for RG174 and RG58 depending on what I went for and its purpose. They are also a good fit for the vw/skoda components.

Im a mechanic/electrician by trade so my roots are well set in the wiring side of things!

[ApertureS]

Thought id get round to the job of terminating all the data connectors today under the OSF seat.

This meant terminating 4x HSD connectors and 4x Fakra connectors as well as fitting the TV tuner and the 360 camera control module.

 

For the 360 module i decided to extend the cut out that is under the TV tuner bracket and this allowed perfect fitment on top of the rear footwell duct.

 

 

The TV tuner bracket was fitted back on top of it and the tuner fitted. The 3x fakra connectors were terminated and the wiring and MOST cabling ran. This all got ran under the seat, along the floor and up into the A pillar ready to continue on up and over the dash.

(I am one double fakra connector short for the tv tuner as photoed, it has been ordered.)

 

 

Whilst in the area the wiring for the ventilated seats was also started, this is simply a ground, power and a LIN signal back to the BCM. 3 wires started and ran into the a pillar area as well.

 

 

Last job of the day just so i could sit down and rest my knees - pop out the old parking button assembly and fit the new one in the 360 camera logo. No functionality different, but the emblem is different (Sticking to every detail)

 

[ApertureS]

So today involved starting to fit the bits in the engine bay - this is where the real hard work is!

 

We made a start on the following:

-Webasto heater and parts

-Wiring loom

-Wheel arch wiring

-DCC sensors

-Front camera wiring

 

So to start, the front bumper and wheel arches came out to give more access as well as one of the headlights. The webasto was test fitted in place and the wiring loom mocked up as photographed below

 

 

Once mocked up, the main bay loom was detached and given some slack and all the tape was removed - the new wires were attached and ran inside the loom and it was all rewrapped. As the loom worked its way back towards the bulkhead we needed to sort out the next part, the OSF wheel arch wiring (getting this out was an awful job as the brake servo is extremely tight to the wiring!) A bit of wiggling and persaution and it came out and could be replaced and rewired. Whilst here the OSF level sensor was fitted with a M6 bolt and M6 nut.

The part numbers are OSF 3Q0412522A and NSF 3Q0412521A

 

Next up the HSD waterproof cable was ran from the centre lower grill, up and into the main loom and off to the fuse box area, meaning the bumper hopefully wont need to come off again as the cable is all tucked next to the battery for now.

 

 

The webasto was then fully bolted up and the wiring and fuel line connection attached. 

 

Webasto fitting is almost complete now! All that is left is the long coolant pipes, the rigid metal pipes and 2 replacement pipes that intercept the heater matrix pipes.

This is where we have serious issues now! So being the first to do something means you run into a lot of issues..... the issue being all countries that have webasto fitted or as an option (cold climates) are LHD! This meant a RHD rigid metal pipe was never created and simply does not exist.

Here is a photo of the pipe in question:

 

The pipe runs along the right hand chassis leg, across the bulkhead and to roughly the centre of the bulkhead - the difference between LHD and RHD, the steering column and rack side! The damn bulkhead bulge is in the way and this means 100% there is no way of fitting this rigid pipe. Ive checked every single MQB car for a RHD option and none exist. This leaves me with a few options now, the first is give up, which I wont be doing, the rest are as follows, but with the crux of - I wont be able to size/measure/fit anything until the subframe is dropped and the rack moved out the way.

 

Modify the pipe to fit - means shortening the bracket that runs behind the column by around 1-2 inches, but this makes the pipe 1-2 inches short, this gap could be filled with a silicone hose or a welded pipe and that is still assuming the rest of it will fit the contours.

Cut both ends off - this will leave me with both ends intact, each with a mounting point and the 2 hose attachments, it then means the centre piece will need to be custom made to go in front or behind the column using silicone piping.

Dont use the pipe at all - Cut the quick connects off both ends of the car piping and use nylon joiners to create a fully silicone/rubber coolant pipe that would need heat shielding from the exhaust.

 

None of these options are ideal as they dont meet the goal of fully OE but im thinking a mix of idea 1 and 2. The issue is once the subframe is down and if the pipe cant be created quickly or if i need to order more parts it means im without a car for a while... 

So for now, we will put a pin in this and as a worst case, mock something up when the subframe is down, and then come back to it at a later date 😞

 

For the amount of work so far, This being the only set back isnt the worst thing. 

 

 

 

 

Tomorrows job - finish the bay wiring and tuck it next to the ABS module until the dash is out, fit the remaining arch loom and DCC accelerometer sensors, terminate the engine bay fuses but dont fit the actual fuses yet.

iIs it not possible to have these pipes remade, or do you need a pattern to work to? Webasto sell the heater to fit the Superb, it is just the heater and no ancillaries they market?

Id need a pattern to work to that doesnt exist sadly. I could mock something up in copper and get it remade in stainless/tig welded by someone possibly. Rubber will be the cheaper and easier method by far! Webasto sell the heater only, the rest is made by skoda suppliers/manufacturers. 

Looking at this manual for aftermarket webasto - it only lists left hand drive
https://az666937.vo.msecnd.net/32/e2611f3b-4188-400d-86e5-7e4a9e72efac.pdf

[ApertureS]

So ive looked at the above manual in a bit more detail and seeing the approved method from Webasto, ive decided to go for a hybrid of OE and Webasto in terms of piping. 

So ive ordered 2 meters of 19mm coolant piping, a handful of straight/90 degree fittings, some heat protect and some P clamps and then once it all turns up, we will see how it goes!

The 3 points i plan on mounting the pipes are: On the bulkhead where the O2 cable connectors are, Behind the steering column on a short M6 thread and finally on the right chassis leg where a rivnut will be added.

 

Ive got a week off work at the end of the month to put a big dent in all these retrofits again! Maybe even finish some of them.

 

 

Also call me crazy.... but I have priced up and checked out the viability in the future of retrofitting a panoramic roof (Seen as i need the roof painted anyway, why not replace it!)

Youd be suprised to know the OE fitting procedure for a roof panel is about 1 litre of 2-part structural adhesive, 400ml of 1-part adhesive, a smear of seam sealer and about 20 resistance spot welds. No full welding required anywhere!

(Wouldnt be doing this anytime soon, gotta get all the above fitting and running first!)

Errr. What! Thats the first time I've ever heard of this. 

At the beginning of this thread I just thought that you were extremely enthusiastic, but now... I'm inclined to agree. You are crazy, but in a good way though 😁.

Hey? AS? Why don’t you consider converting it to a 2 door coupe whilst your thinking about fitting a pano roof… 🤩

Todays work is underway!

Gonna be in pieces for an estimate of 4-5 days with the amount of work going on!

 

[numskull]

AS? You have balls bigger a superyachts fenders…

[ApertureS]

So this week involved the final push for all the wiring!

Bringing (almost) everything together and even getting some bits finally working. 

 

So to get started the entire dashboard had to come out - Ive done this too many times now that i can whip it out in under 2 hours  

The photos also show the sheer amount of wiring that was tucked behind the drivers footwell

 

 

Once the dash was out it was a job of locating where all the wiring was going as well as adding the extra wires for things behind the dash

 

So basically everything on the right side of the dash went to either

• left footwell to join the engine bay harness
• fuse box
• BCM

everything in the right footwell went to either

• centre console
• fuse box
• BCM
• 5F radio

Then the following was added behind the dash into the rat nest of wires

• power and ground for heated steering wheel
• USB hub HSD cables, power and ground
• Wireless charger harness which split to 5F, fusebox and to left footwell
• MOST cables from TV tuner to instrument cluster

There was also a few wires to neaten up on my travels. So once all the wires were roughly draped in their needed final locations it was then a job of wrapping harnesses to secure all the wires and give it that OE look.

 

Sadly didnt get any photos after this was all wrapped and secured but basically, it looked like no one was ever there. 

 

To show the extend of the modifications, the fuse box now gained an additional 9 fuses!

 

A small side note but something that was on my list - everytime the car was started I was greeted by what can only be described as the car yawning at me - the grease on the heater direction flaps had dried out and caused as a squeaking sound almost.

So the motors and gears came out, all grease was removed and relubricated with lithium grease.

(Even with the entire dashboard out, some of these motors were near impossible to remove!)

 

 

Back on track.... so all powers and grounds ran, all wires in their final locations, now time to terminate!

• A custom fakra to quadlock micro pin was created at the 5F unit which is a fancy way of saying, the outer braid had its own terminal and the inner core did too. This was for the 360 camera video feed to the 5F.
• A few wires were added to the gateway canbus wires as it was the easiest location to access them.
• A fakra connection in the centre console was added for the signal booster from the wireless charger
• HSD cables were ran to the rear of the centre console for the usb hub and the usb hub tucked under the centre console area
• 4 wires were added to the BCM - ventilated seat LINbus, wake up signal from charger, wake up signal from DCC module, heated washer jet power

One of the hardest parts came next, 16 loose wires in the left footwell with nothing to connect to! The wires from the engine bay now needed to get to the left footwell and the access point is buried behind the complete heater assembly and behind the ABS module. Neither of these were coming out so i struggled for hours to run the wires and securely waterproof the OE gasket with my new wire feed.

First picture shows where it was buried, second shows the wires now emerging.

 

16 wires, and a HSD cable.

 

 

All 16 wires were then terminated male and female and the new red plug was added and connected (look factory enough for you?) the blue HSD connector was then terminated male and female and connected up.

 

 

 

And this basically summed up the wiring!

• 4 days work
• 150 meters of loom tape
• roughly 530 meters of new wiring
• a lot of blood and sweat

 

and what do we have to show for it.... well youll have to wait for the next post!

If it was a factory option, i see no reason it couldnt be done.

 

The only issues will be because the car is on the newest platform with a lot more back door and modification protection - it would make the entire job harder just from a software point of view

I did think it might be tricky, as there is no physical button and turned on via a virtual button on the screen.

[ApertureS]

A little taster....

 

[ApertureS]

So a few further updates:

 

• Areaview fully coded and 'working

The coding for areaview is actually really straight forward, the hard part is the hardware and wiring.

Gateway - Install list - Add 6C (same as reverse camera)

Parking Sensor - Coding - Change to areaview camera type '20'

5F Infotainment - Adaptation - VPS_0x0B to activated

Then all the relevent coding in 6C areaview (manual/auto, bodytype, make, model and such, same as reverse camera again)

Dataset needs uploading to 6C - only datasets I have are tiguan, passat pre-FL, passat FL

Calibrate the camera using vas721001 calibration mats and a diagnostic tool

 

• Now I was unable to calibrate the areaview as it keeps picking up errors on the front camera, both sides and rear are perfectly fine.

 

The red lines means its detecting part, but not all it needs (turns blue when it finds all it needs) the yellow dots in the sky are things it thinks its looking for, so that gives us the next issue to work out why and ive narrowed it down to many things:

• The mats need to be wrinkle free
• Needs to be done indoors with uniform lighting to prevent sky issues
• The calibration mat isnt perfect as the forward white lines SHOULD go directly to the end. not stop short.
• The dataset currently on there is for a tiguan which has a different camera placement, i may try a passat pre-FL which is much more similar to my setup.
• The camera I have fitted is too low and not in a suitable location, could try lifting the car up level on bricks 2/3 inches or may end up having to change camera mounting location, yikes.

All of these need to be worked out so i can fully calibrate the system and have a seamless image.

 

                                                                                                                                                                                                                                                                                                                                              

 

Next up, the heated washer jets were coded, real straight forward:

BCM 09 - adaptation - Window heater-Waschduesenheizung to active

 

                                                                                                                                                                                                                                                                                                                                              

 

The heated steering wheel again was real straight forward and all done through HVAC 08 - coding:

Byte 11 bit 2 - 1 (Enable heated SW)

Byte 11 bit 3 - 1 (Enable multi-stage heated SW)

Byte 13 bit 2-3 (Decide if you want it to auto come on with the heated seat or outside temp)

 

                                                                                                                                                                                                                                                                                                                                              

 

The phone charger with antenna base again, very straight forward on coding, all in 5F infotainment - coding:

Byte 15 bit 0 - 1 (Enable baseplate)

Byte 15 bit 1 - 1 (Enable antenna amplifier in baseplate)

Byte 15 bit 2 - 1 (Enable wireless charger)

 

This came with a fault code - B156401 - Antenna for telephone mount, electrical error and working out exactly what this fault code relates to will be fun, the below are the options that need further diagnosis:

• My coding has a possible problem and im either missing something or wasnt meant to enable bit 1
• My fakra cable from charger to amplifier is faulty
• My amplifier is faulty
• Amplifier not receiving power, ground or switch on signal
• Faulty charger or roof antenna (but both brand new so id hope not)
• Faulty fakra cable between amplifier and roof antenna

                                                                                                                                                                                                                                                                                                                                              

 

The USB hub was next, this added a second USB port in the centre console that is fully supportive of carplay/android auto and everything else and coding was very simple again, all in 5F infotainment:

Byte 19 bit 6 - 1

Byte 19 bit 7 - 1 (Both of these will already be on if you have a carplay/android auto USB port)

5F Adaptation - 

Interface for external media activation - connection 1 → activated

Interface for external media activation - connection 2 → activated

 

Straight forward and no faults with this, fully working and no issues!

 

                                                                                                                                                                                                                                                                                                                                              

 

The TV tuner was next, now this im only half way through sorting and have yet to disable component protection which means i cant currently see anything and my TV list only shows liverpool tv, so something is very very wrong here but im yet to work it out. 

There are no faults for any open antennas or such, which is a very good start!

The coding so far is as follows:

5F infotainment - adaptation:

Gateway component list: TV Tuner - enable

TV_tuner_0x2C - enable

TV_tuner_0x2C_msg_bus - currently not sure, possibly Terminal 15?

menu_display_tv_tuner - enable

Gateway - installation list - 57 TV tuner

 

Now with this coding I have no fault codes anywhere except component protection, which is a good start!

Im yet to fiddle around and see if anything works on this side so when i find time ill do this

 

                                                                                                                                                                                                                                                                                                                                              

 

In preparation for the DCC retrofit, A custom gateway FPA dataset is required, this now gets a small bit complicated.

So a lovely gent managed to decode the entire gateway dataset to allow reverse engineering. The only issue, you need to have a gateway with at least version Q, mine was C.

 

I thought id give it a go, so first I intercepted my own dataset from ODIS for version C of gateway, when looking at it under a HEX editor you could see the differences already between a version C and Q dataset. Namely the section that holds the FPA data starts at address 0B80 on a Q dataset and is exactly 4352 bytes.

On my C dataset the address with 4352 bytes started at 0320 which is NOT 0B80, this is an issue. 

I tried picking out the individual bits I needed but this was no good. Annoying as I would of prefered to make small changes to my current dataset instead of creating one from scratch.

 

Next I scrapped the idea and started from scratch and began using the FPA editor to create a dataset - http://www.mqbtools.nl/fpa/

Once this dataset was done, I couldnt upload it as its only suitable for Q and onwards software. So the gateway module now needs an update!

 

There are two paths for 19 gateway modules that are 3Q0907530 - Lear and Continental. Both have the same suffixes for hardware and software but are NOT interchangable. If you do that, youll brick the module.

So as I have continental (can read through diagnostic or physical checking label) I know that my software numbers start with 5, whereas lear start with 4.

 

So my continental software was C - 5287 (Lear C - 4287) and I needed to get to at least Q - 5344 (Lear Q - 4344) (With gateway, as long as its a valid software, you can flash forward, backward, skip some, do whatever. No risk of bricking)

So I made the choice to jump to the newest version which is AC, or in full 3Q0907530AC - 5388 (Lear 4388) after this, everything worked perfectly except for loosing coding, adaptations and many fault codes.....

I then used ODIS-E to reconfigure the coding and adaptations to what they were before, no issues here and now almost all the fault codes are gone and no more dash errors.

The custom made dataset was then uploaded to the module (ODIS-E did not like this but still accepted it) as the checksum was incorrect, but still a valid dataset.

 

 

The only additional coding to enable the DCC options to appear in profile selection was 19 - coding - FPA_Funktion_DR (DR for damper regulation)

 

Everything is now working, but im left with a single fault code that there is no documentation on "00301 - 769 - C115531 - Analog measurement input, No signal" and although it causes no issues, This will be a seamless build with no faults left so i done some digging.

I found a single other person who had the same issue and they advised I roll the software from AC to AA - 5366, I am yet to try this but I have acquired the software, so that will be my next test to see if it fixes it.

 

The only saving grace, all datasets for anything from Q to AC are the same and can be uploaded with no issues.

 

We currently have a working DCC slider and options displaying (but of course not doing anything until the coding for DCC and damper fitting)
