a4qa 2.0tdi 177 - dash warning "steering fault - do not drive" + no power assistance

[b206]

If you were at full lock and your mirror was knocked by some **** then they probably knocked your wheel as well. Something is obviously damaged.

You need to get it diagnosed properly - either garage or find someone with VCDS. If you have an error on the dash it will be logged.

No point buying expensive parts hoping they fix the fault.

yes I thought same and checked the tyre and rim, nothing. have had is scanned with vas5054 device and controller doesnt respond. tried to tell it a new rack fitted please readapt and still it wouldnt play, seems something pooped inside the electronics.

had a rack paid for and being sent, but they found it damaged and cancelled/refunded me dammit... so looking for a lster version for reasonable cash, or bbreman will repair it but means car off the road for a week while htey do- they have no spare ones on the shelf for now.

The Russian thread does seem exactly analogous.

so another late model rack coming. mechanic and me at odds whether it will fit. breaker/dismantler sounded confident and knew his audi vehicles, the russian thread also says any revision of the rack will fit/work so I'm hoping so. Hope to receive rack by end of week, and fitting could be saturday am if all goes well. had a lot of bad luck recently so somethings gotta go my way.

ok so its going in for the rack to be changed over tomorrow am (Thurs)...

[LeeTanczos]

ok so job done, rack changed over, tracking set up, rack coded to car and all good. steering assistance restored... been driving it for a fortnight unassisted so seems far too light now... combination of being fixed, plus I think possibly they gave up with the steering feel on this rack version or the software is a version which doesnt give as much feel/ is over assisted. there might be some options to the level of assistance I'm not sure, will get used to it anyway to some extent I am sure... what a relief to be able to drive wherever I want now with relative ease haha. so now to see if there is buyback anywhere of the defectice rack for reman purposes...
