HI,

I read all treads and I didn't find the right answer for me. So here is my problem.

I have Cayenne S 2004, with steering angle sensor problems. So PSM is not working now.
I read the faults and the only one is:
0778 Steering angle sensor No signal/Comunication Present.

I make test with diagnostic, and there is no CAN communication with that sensor.

So I bay new sensor, change it and no difference. The actual value is always 0 degrees. I also check all wires from PSM unit to steering column, and gateway, and is all fine.

Can please someone help me, coz I don't know what to do to repair this problem.

Could be the problem in steering column electric unit?

I know, that sensor has to be calibrated, but fist the system has to communicate with it and give same values, than has to be calibrated.
Is that right?

Please for some help.

Thank you

Gasper
