Check power suply , grounds and can bus......

possible bad abs modulator also

Power supply checked, ca bus comunications is ok, the ground cable is good too, so i dont know how cant measure more than 172 grade +,-.
In ABS, i cant make basic setting for steering angle senzor, but in steering wheel i can....here a see that steering angle senzor is not initialized.
Have anybody changed steering angle senzor for this type of car before?Audi A4 2009.
Must do some other special procedure?
Thanks.

I have exactly the same problem - tried 3 different G85 and all of them in VCDS show:
00778 - Steering Angle Sensor (G85)
014 - Defective

and all 3 of them work from 0 to +175 and them jump to -175 to 0

Thanks. In my case first three G85 were defective. Fourth was a good one.
