Good day, Today on my Cayenne S 2003 I get PSM Failure Workshop message. Yesterday we worked on the front suspention and I didn't made alingnment of the front wheels. We repalce both left and right lower carriers. We mark the excentric washers but after the replacement the steering wheel is not straight, but is like 15 degrees turned. Is it possible that I get the error message becouse of that?

 

Yes - that's possible.

 

Get the cayenne aligned and drive it. See if msg goes away. If it doesn't, take to a shop.

 

You got the infamous Steering Angle Sensor calibration way off. Re-do the alignment and get Porsche to fine-tune the centering of the steering wheel.
