Hello All,

i've fitted a westfalia removable towbar along with "dedicated" electrics (my a**e)....plug and play they are not. Anyway, I took so long to fit it that i'm sure that all wiring etc is correct.

I purchased a legit VCDS & Vagcom reader.

I've checked through everything I found online - resetting DTC's; coding the tow bar into the system. But I've been left with a few errors which no matter what I try I cannot get rid of.

 

In summary - its a Westfalia electric kit from PFJones designed for Skoda Superb III/Golf VII/Audi A3.

Electrics work okay.

Plugged Towbar bike carrier in and all electrics work okay.

Rear parking sensors disable when tow bar electrics plugged in - and there is a caravan picture on the dash.

 

Problem I have is with the Cruise Control with Front Assist (ACC). It says not available :(

I've checked and reset all coding to no avail.

 

I've included a print out below - if anyone would be able to help look at the coding it would be most appreciated.

 

The grille sensor is completely uncovered and undamaged. It only stopped working when I connected wiring for the towbar when I had to disconnect the battery.

I am no expert but would it be possible you connected the acc to power the trailer as you have an open circuit fault on the mod69 ?

Did you try remove the coding you put in and disconnect trailer wires or fuse you installed and see if acc fault clears

hi, thank you for the replies. yes, I checked all wiring and have removed all coding and the ACC then works.

I heard from the place I bought the kit from over the weekend (PF Jones) who checked with their technicians/fitters. Apparantly the ACC needs coding specifically done by a Westfalia coding device - and cannot be done via Vagcom/VCDS. I'm waiting to hearing from the local Westfalia installer to see how much they will charge to do this.

Oh well, considering Skoda quoted me £957 to supply/install and i'm currently at £570 for parts/VCDS I've a little to play with.

I'll update once this is sorted.

 

In the meantime, if anyone else is planning to do this, just be aware that you may need the ACC coding separately.

just spoken with an independent fitter. He said it does need the Westfalia device as it needs some "FR coding" changed. He was impressed i'd been able to do the wiring as he said "it was a pig". Will charge me £50 to sort it next week.

Sounds like a good compromise, and glad you sorted.

Thanks for the info, I fitted the same towbar also from PF jones, I considered the dedicated wiring but opted for a generic by-pass relay, obviously I dont have the benefit of the parking sensor isolation but I'm more than happy with my £200 spend, I did the same with my 2 previous superb II's.  

quick update on this issue.

 

I still have the ACC and front assist problem - it not working.

 

A Westfalia installer has tried to do the coding to no avail; luckily he didn't charge me as it wouldn't work.

 

I'm nervous to take it to Skoda dealer to have a look at just incase that say the towbar wiring has voided the warranty.... :S

no wires were cut - but to fit the wiring loom you have to remove a couple of pins from the Skoda BCM module; then loop them out into the Westfalia loom. i double checked the wiring last night - took 4 hours to remove dash, check all wiring and then attempt to reset codes using VCDS. 

Ross-tech are looking at my coding - the first reply i had from them removed a couple of errors, so now i am left with the unfunctioning ACC/Front Assist.

 

Bit of advice....if you are thinking of a Towbar, the £900 or so quote from Skoda is now good in my eyes. I've spent at least 20-30 hours fitting the towbar; installing and rechecking all wiring; and hours on VagCom/VCDS. Thats on top of the c.£550 i spent on the towbar, loom and Vagcom :(

 

Mrs StuT4 is not a happy bunny at the moment.....

My main reason for ordering a new superb was to get the factory fit Tow bar, at £795 including "preparation" of battery alternator and cooking system, it seems a good price!

Sorry to hear of your troubles.

 

I ordered the factory fit towbar as at the time of ordering PF jones or anywhere didnt offer a aftermarket towbar and it was still in design. - glad i did now.

 

best of luck with it...

 

Is it not possible to revert all coding and unplug the wiring to go back to sqaure one to ensure ACC then works again ?

i kind of wish i hadn't bothered with it now....i only use it for a towbar bike carrier :(

if i'd done a factory order i would have ordered it with the towbar, but i bought mine as a car which the garage had on order to be used as their demonstrator - so i got it before it was registered. 

 

thats what i might need to do...

 

i've just found the closest Skoda deal which has the equipment needed is c.50 miles away, so i've just booked it in to have it looked at - just hope it doesn't affect the warranty... it was a westfalia wiring loom - which supposedly is what they use if its a dealer fit towbar/wiring...

update.....

i received some good advice from Ross-Tech regarding correct coding to get the towbar installed okay.

for some reason though my Adaptive Cruise Control and Front Assist stopped working.

 

The only solution was to take it to the local dealer and c.£220 later they have now reactivated and recalibrated it, so its now working

 

They said it could have been hit by a stone or could be related to the towbar fitment - either way, i'm pleased its now working and kinda wished i'd spent the £1080 i'd been quoted on a dealer fit towbar, as to date i've probably spent £590 (inc £260 for VCDS) along with the £220 today, so already in for £810 plus about 30 or 40 hours in fitting and diagnostic work!

 

So, given the choice again i'd get it done professionally rather than a DIY install!

 

 

quick update on this.

 

i was sat in a slow moving traffic jam in france last week at 39'c - which was stop/start for 100+ miles.

the brake/sidelight bults in my rear cycle carrier must have overheated as i suddenly got a message saying a "trailer bulb" was out. I also had a problem then with the ACC/Cruise Control.

 

I pulled into the nearest supermarket - changed both bulbs in the cycle carrier. When ignition was cycled off/on it then all worked okay.

 

It appears that on the towbar electrics it must sense a blown bulb and deactivate the ACC. Luckily 2 x 50 cent bulbs fixed mine.

 

After that I also turned off the DRLs for the car and towbar (as per the VCDS guide) to avoid them being left on continuously when I was in stop/start traffic in such a high temperature.

 

Turned then back on for the return leg to the UK, and all is fine and dandy.

Had a Westfalia aftermarket towbar with dedicated electrics fitted on Saturday and like you, my Front Assist and ACC are no longer working. The guy who fitted it all was very concerned and is going to find out today what he needs to do to get it working for me. He thinks it's a coding issue and that the software he has is out of date. He's fitted several towbars to Superbs before but this is the first time he's fitted one to a Mk III. I hope he gets it sorted.

There is a fault whereby the ACC is lost. When I had my aftermarket one fitted, I too lost the ACC but the fitter understood the background and was able to re-code correctly. The error originally started in the VW Passat where there were similar issues.

 

 

All sorted now. The company who fitted the towbar updated their software then updated our car. Happy bunny now.

Hi. Need help as well. Got a genuine sviwel towbar installed myself skoda superb mk3 2016 se 150hp).

 

I have bought the trailer control unit separately ( 5Q0907383N). I was doing coding using vcds. All was good until i connected the caravan and trailer.. The porblem ia thta the lights are not working properly. Right turning light not working at all.. Left works with the brake at the same time.. I thought as it is aplug and play (my car was trailer prepared so all the connection was at the nack of the car already) then i shouldn't have a problem. My question is : do i have to reprogram the control unit to make the lights to work properly? Or there most likely will be a trailer to control unit wire that is not broke or not connected properly. Thanks.. I didn't wire anything as was juat plug and pay for me (2 connection outlet from the car fuse to the control unit and 2 from the trailer to control unit
