Hello everyone, 

I have decided to retrofit Blind Spot Assist myself. I am currently gathering information and materials.
I will share my efforts with you as they unfold. I don't know if I will succeed, so I haven't yet predicted 100% success.

 

The information concerns material codes and  the method of their installation.

Finally of course there is the programming of the system which will be done by on-line connection to the VW servers.
So, so far I have collected some materials.

 

The schematic:

 

The codes of the radars:

 

 

 

The brackets for the radars

 

To be continued...

I  am almost done with the materials. 

Here the most important. 

 

 

• Left radar 2Q0907685H 
• Right radar 2Q0907686H (master)
• Bracket on the left 5E6907456A
• Bracket on the right 5E6907457A
• Connectors for radars [2pcs] 1J0973714 and pins 000979038
• Plastic nuts for brackets N91018901 [4pcs]

 

I desided to do the 100% retrofit, so i bought mirror caps and the LED warning lights:

 

 

 

 

• Mirror caps   Black Mirror Cover Kit with Indicator Holes 5E30722530C F9R
• LED warning lights for side mirrors Left 5E6949145
• LED warning lights for side mirrors Right 5E6949146

 

I searched a lot to find the name (code) for the LED warning light connector. Finally i found it:  

 

• Connectors for LED warning lights MX19002S51 [2pcs]

 

 

 

 

 

 

And a pair of connectors, for the wiring inside the front doors:

 

 

• Connectors for door wiring to mirror: 1J0973119  [2pcs]  & 1J0973332  [2pcs]

 

 

Next step: The wiring (i desided to do it myself).

This would be wonderful to see how you would do it. A video tutorial would be great.

hello

 

I'm trying to do the same except in my case I'm using a different system, so I need the wiring diagram of the tail lights (turn signals and back light) do you have it??

Happy new year everyone.

 

I am procced with this project. 

 

I made the wiring.   

 

 

 

And a

 

I made it according to the electrical schematic (i posted it at my first post).

 

Next step is the physical installation   of the radars (need to remove the rear bumper).

 

 

Those are the original places of the radars

 

 

 

So, the first step for the installation, is to remove the rear bumper.

 

 

 

 

 

To achieve this, one must first remove certain other things.
1st the luggage loading edge

 

 

 

 

 

2nd the taillights. It is not mandatory, but I recommend it so that the bumper can be easily removed from its clips and no damage is done.

 

Now we are ready to remove the bumper. 

 

 

 

Pull the bumper outwards, disconnect the cable (if any) of the reversing sensors. I suggest putting a protective cloth, plastic or something else on the floor, so as not to scratch the paint.

 

 

 

 

Done!!!

 

(Note, in this photo it appears that the luggage side trims of the trunk have also been removed.

This is necessary to do so that the wiring to the radar can pass through, I will show it in a next post)

Hello @Giannis20,

Can you give more details about the rubber waterproof  covers for the electrical connectors, please?
I've took a look on AliExpress, plenty of them, I don't know which one to choose: 3P, 4P or 5P.

Any advices are highly appreciated!

Good luck with the retrofit!

Cheers.

Hi, 

it's the 2P 

 

Hello @Giannis20 ,

Can I bother with another question related to this retrofit? How did you connect the power source for the modules/radars? Have you used a piggy-back cable to connect on an existing fuse OR have you tried to insert a new connector for a spare fuse in the Fuse holder C underneath the dash?

Thank you

Add a terminal via the back of the fusebox, it's easy :-)

@East_Yorkshire_Retrofits , Thx for the reply!

But, it might be easy to add new terminal in a spare fuse location only for RHD vehicles, since the fuse box is located behind the glovebox.

For LHD, you don't have access to purple security bold because this is located behind the dash panel, so you don't have enough space to pull the fuse box at least a little bit to work on it, like it was with previous MQB model. I'm not planning to remove the full dash just for this, that's the reason I've asked @Giannis20 to find out his solution.

For this retrofit, I'm going to connect the modules via a piggy-back, quick and easy fix.

Cheers

You don’t really want ADAS systems powered by a fuse tap, you need a secure connection that cannot be affected by vibration

Thank you @East_Yorkshire_Retrofits for this valuable information.
With regards to the above can I bother you with one more question:
What terminal type are required for the ATM (mini fuses) connections?

Cheers

#Retrofit continues

After removing the bumper and the interior lining of the trunk, it's time to install the radars.

Now it's time for the fun part, the wiring.

the schematic

I read that someone use the rear camera wiring to connect the BSD radars with power and Canbus net.

this is the schematic of the rear camera wiring.

The place of the rear camera wiring is very convenient, is at the right side of the trunk, and has an easy access. it is behind the luggage compartment side trim.

I decided to use the same idea.

I also decided to use a 4pin connector for my convenience. This is the result.

I root the wires thought the rubber gromets at both sides of the car.

And inside the trunk.

Connected my 4pin connector.

Done!!!

The only thing left is to root the wires (green and yellow) to the front doors for the notification indicator.

Hello @East_Yorkshire_Retrofits ,
I might need some advised from someone with real expertise on this kind of retrofit.

I managed to route the cables through the mirror lamps, but I'm afraid I can't find verified information related to harness connection, especially to T2b pins?
1. Which is "+" signal and which one is "-" ground? Do you have any pictures with the pin numbers?
2. Is the harness connection the same for right and left mirror lamps?

Really appreciate your support.
Br,
D.

Edited 30 March, 20251 yr by djmartzian

It’ll only work one way, and won’t damage anything connected the other way. Both left and right are the same

Thank you @East_Yorkshire_Retrofits for your quick reply.

Are the lamps 5V or 12V ?

I would like to try them on bench and prepare the harness before fitting them on the mirrors/ car.

All the best.

Hi all,

The answer to the above question related to polarity of the harness connection from the mirrors lamps.

Cheers.

The retrofit is stuck in the process of registering the new radars through the online connection. So far, no solution has been found. The car's BCM does not accept them, because they are not registered in the car's VIN. It seems that the end of the retrofit is near, at least for the MQBEvo platforms.

Any help would be appreciated.

There's nothing to stop you removing component protection on retrofitted modules :-)

You'll need to manually configure the radars, SVM will not work due to them not being fitted at the factory. CP can be adapted, the gateway is the CP master not the BCM. BCM is immo master

Thank for your help.

Just to clarify i have to remove the CP via online connection, and all the other part i need to do by myself (coding, adaptation and dataset download to Radars) WITHOUT connection to SKODA servers?

Correct. We can configure the modules remotely for you, assuming the garage you’re going to has a genuine VAS6154/A/B or a VNCI6154A

We can’t adapt the CP remotely though as this goes against VWAGs policies.

Thank you so much. At the first opportunity, I will visit the garage I go to and remove the Component Protection.

I have a cable (clone of 6154A) with ODIS 24.1. It's very possible that I'll need your help remotely. I'll try on my own first and if I can't, we'll talk.
