Passat Variant TDI B8

**mikeman** · 28-02-2024,02:10 PM

Dear VW-users,

I am in a need of help with deciding what should be done about the below DTC errors that had already popped up 2 times for my Passat 2.0. TDI Variant 2019 (pre-lift).

What happened:
at some point when I started the engine, I got several control lights and info like: Front assist failure, ESP failure, Tire pressure check, park assist failure, failure: road signs recognition. Total of 7 errors. I connected my OBD and scaned for DTCs - the result can be found below. I cleared the errors twice and it was ok. THen couple of days later I received the same set while driving slowly through quite mesy and bumpy road - again: cleared the DTCs and it is working.

Background:
The car was hit in front right wheel and got replaced bumper, wheel with its whole column, some electric stuff and other items including steering wheel column too. I replaced the battery too after I got it a year ago and till now it was running flawlessly.

Right now it is working again, but I want to be prepared what to do if the errors wil continue to appear - what to be prepared for and what to check when they happen. Can you please help?

To me that looks like the radar unit in the lower front grill has got water in it, makes the car go nuts.

Would you mind sharing why you think so? Is there any particular entry that suggests that it is exactly that and not other items? I was assuming rather rotation angle sensor or steering wheel pump or maybe faulty harnass or so - because the errors of all those items but also rear camera/ park assist sensors would be quite far from the radar (which indeed was also replaced or at least re-fitted in the new front bumper afther the car was hit).
