Help with fault code/DTC: Steering Angle Sensor (G85)

[A4x]

I've been getting this annoying DTC everytime I turn my car on. I have cleared it with VCDS but it comes right back again next time I start the car. Does anyone know how to tackle this? Some ideas I have are:

1. Recalibrate the G85 sensor (steering angle sensor) with VCDS.
2. Unplug the clock spring/steering angle sensor and ensure plug is not damaged.
3. Replace the expensive clock spring/steering angle sensor ($$$)

Or I wonder if this could be a bigger problem like a wheel bearing, or alignment off. But I don't think so. I also wonder if a low batter voltage could cause this? My battery is original, and I am due to replace it before the winter hits.

I appreciate any help or advice you can give. Has anyone dealt with this code? Here is what Rosstech suggests:

Here is the main code from the Steering wheel module:

What does the g85 read at straight ahead 0deg? Will it go out if you turn the wheel and then drive?

What does the g85 read at straight ahead 0deg? Will it go out if you turn the wheel and then drive?

Reads 0 degrees when wheel is straight. It appears to give normal readings when I turn the wheel left or right while parked. I have not driven then car and checked this. I get the DTC IMMEDIATELY when turning the car on, or only a few seconds after starting to roll.

So maybe I should try to check the live reading from the G85 as the code hits?

Anyone know if it is even possible to separate the G85 sensor from this whole assembly?

I read the live result from VCDS as I turned the car on today. Readings were normal. The code appeared as I was turning the wheel with over 200 degrees of position, but the code always says 42.5 degree steering angle! I cleared the code while driving and it immediately comes back with 42.5 degree steering angle.

I don't have dynamic steering, and that seems to apply to dynamic steering.

I did try this calibration, several times today, and the error keeps coming back with the exact same code! 42.5 degrees! Seems to be when I turn the wheel right.

Anyone know what a bad clock spring would look like? Could a bad clock spring be throwing this error code? I took my steering wheel off to inspect. Keep in mind, this has been making a slight squeaking sound for over a year now. I found grease outside of where it should be, even a little was on the back of the steering wheel.

Bump. I bought a used clockspring (still installed in entire stalk assembly) from eBay for $90. I messaged a few buyers and made sure to get one where the airbag did not deploy. I have not installed yet. I am still faithfully getting the same error code everytime I start the car. Will update once I install...

I would do a basic setting for the g85 then do a steering stop limit basic setting
