I have a manual 2010 C4S with 20K miles on it. For the last couple of months I have been getting these warnings on the dash. It only happens at low speeds and while I’m turning the steering wheel. Usually when I’m backing into my garage. It goes away when I drive in a straight line over 10 mph. Sometimes as I drive away, after I’ve had the PSM Failure light, I get the Drive Off Assistance Failure or the PSM Initialization or the PASM Failure. The messages after the PSM Failure goes of are very random, but are always one of the three listed above. The car drives great and this only happens while driving slowly and turning the wheel. It always goes away at around 10 mph. This doesn’t bother me a ton, but if someone could help, I would appreciate it. I own a Jeep Parts and accessories business with a ful service department, but not typically a Porsche service guy.




The car has the fabspeed headers, intake and tune with HR springs in it. It had the fabspeed cats as well, but it was way too load, so I put the original cats back in it.

Any help would be great!!

wheel speed or steering angle sensor maybe? Potentially low battery voltage.

Bet my left nut it’s a wheel speed sensor if the battery is fine.

Would there be a way to check which one would be the culprit without taking it to Porsche?
