(Side Assist) / (Blind Spot Detection & Rear Cross Traffic Alert) retrofit

I guess we need to change ABS sensors on wheels... T6 ABS sensors are not directional i think...
I talked to a friend who did retrofit the 5Q0 907 686 B Radars in a PQ35 Seat Alhambra.
Changing the ABS Sensors for the rear tires was needed.

So looking into the Caddy 2K which uses the same ABS Unit.
Not using side assist but using the Park Assistent.
I can share the coding from the caddy:
It looks like:
To enable Bidirectional ABS Sensors @ the rear axis ABS Coding last Byte needs to be changed from 0x00 to 0x50 or to 0xF0 that is not Clear.
I have seen both in the Field ...

WHT 003 864
WHT 003 864 A
WHT 003 864 B

Are the Part Numbers for the ABS Sensors which are used when "Park Assistent" is available.

Installed the 1K8919472B and flashed to 1K8919472C (was a D option too but same SW)
It works as the 7E0919475 AA
In the coding Byte 1 Bit 6 is the option for the direction ABS sensor installed

Lez, and you already changed the rear Wheel Speed sensors ?
In your screenshot the x is set.
Or can you enable it and you get no error ?
If you have a T5.1 GP than you probably need to change the ABS, too. I am shure that the T5.1 GP ABS does not support Breaking initiated by a ECU in the car.

No I do not changed my ABS, and Airbag modules yet... you can set that I ticked to see if it change anything...

But you have Front Assist. How come?

Got the ACC steering wheel, and the ACC Radar in the T5.1 CFCA ECU you can enable ACC and front assist. But will not work... until ABS ,Airbag module changed...

I checked OEM prices and all of these sensors and they are around €65 mark.
But the question is, will these Caddy sensors fit T6 and are the plugs the same?
Caddy uses the same sensors on both rear wheels and T6 has 2 different kinds on either side. Mounting bolts are the same ;):D

Speed sensors 2pin on both... just the shape and length different maybe... Better to check the T6.1 speed sensors T6.1 have PLA 3.0
 
Unfortunately we will not have the parking curve until we retrofit electric power steering :(
But with this module update now i have front parking assist... pulled in a parking bay and the OPS poped up :)

What about T6 steering sensor?
Would that work for dynamic guide lines?
