RS6 C7 Performance - Steering Angle Sensor Faults - Help!

[TRS6]

Hi Guys,

Has anyone experienced any issues with the Steering Angle Sensor at all?

VCDS is showing a fault stating Upper Limit Exceeded on tolerance along with ABS module fault.

Have cleared it numerous times with no success as it comes back after around 35km or so of driving.

I am wondering if my 21x10.5 et20 has anything to do with it as all the fault codes appeared after fitment of the wheels and nothing prior.

Given many of you change to winter/summer setups. Has this ever been an issue for other owners?

Below are the pics from the VCDS.

Hoping/Praying someone might have a solution for this..

Not suggesting that you should follow this, but it might provide some insight??

The RS6 unit might be different but would seem unlikely for such a common function.

Using the measuring blocks function in VCDS might let you see if the sensor is still measuring steering wheel movement; giving some hope that the limits just need reset by running calibration?

I believe that measurement block for steering angle is in the list - I am overseas at the moment so can't check it in VCDS.

I guess the bigger question may be why it has changed in the first place if it is just the limits!!

Nope

I’ve ran two C7 with various height set ups and wheel combos and had no issues

I’d suggest a faulty sensor??....however with aftermarket wheels you know what answers going to be?

Thanks guys...

I'll try option 1 via VCDS.

If that fails i'll return car to standard trim and take to dealership to inspect.

Appreciate if anyone else has had any similar experience to share your learnings/solutions

Yes, you do that. and the next time any of us here buys an Audi, we'll pay just that little bit more for it so we can fund the fixing of damage caused by your poncy wheels.

Lol! Poncy? Ok captain dealer pack

Highly unlikely that your wheels have caused the fault. The RS6 can handle 21" wheels from the factory and the increase in width is not measured by any sensor. Worse case running increased widths is premature bearing wear.

Thanks and appreciated. This was exactly my thinking.

I'll assume its simply a faulty sensor.

Let's see what Audi have to say when it goes in for inspection next week.
