Hello everyone, I've been a longtime reader on here but finally made myself a account.
I've been having some problems with a 2012 A4 that's been giving me some bother the last week or so, usually I'd work on a problem long enough and I'd eventually find a solution but I have to say I'm beat this time.
The blower motor was replaced this week and I'm trying to see if that's a cause to this. My bother has a older launch diagnostics reader which he used it the clear all fault codes on the car (some where there many months or more) and ever since then there has been 2 recurring fault codes (in the scan I uploaded) basically saying that it cannot communicate with the steering position sensor G85.
I've the full autoscan in this post for someone more knowledgeable than me to look at.
I've tried clearing the faults and they immediately come back. I've looked at the measuring blocks for the steering angle position sensor in both the ABS module and Steering wheel module and its reading Zero all the time no matter what
position the steering wheel is in. Taking the car for a drive did not help at all either.
I tried to follow the instructions to do a steering angle position zero calibration by going into the ABS Module, Login, Entered the security code successfully, I would then click on basic settings, channel 001 and click go. From here on
It actually shows the steering angle but unlike the measuring blocks i was in which was showing zero all the time this actually shows the correct angle/position form the sensor. BUT once I click the [ON/OFF/Next] button to activate basic settings which says off it immediately says ERROR Group 001 Not available across the 4 measuring value boxes. From hear on I'm Stumped, I got a second steering wheel sensor and plugged it in and it gave me the exact same problem again so I don't think it's the problem.
If I knew for sure it was a new sensor I needed i don't mind spending the money on it, I just find it strange that its a "no communication" fault I'm getting and nothing else.
Some help or advice on what to do going forward now would be greatly appreciated.
All the Best, Michael

If I knew for sure it was a new sensor I needed i don't mind spending the money on it, I just find it strange that its a "no communication" fault I'm getting and nothing else.
Some help or advice on what to do going forward now would be greatly appreciated.
All the Best, Michael
