Porsche Panamera 4s PSM/ESP failure

[kubuswujo]

I have a problem with Porsche Panamera 4s 970 from 2010 Year.


Sometimes after few meters sometimes after 5-10km shows on dash PSM failure, and SPORT AND SPORT ULTRA mode does not work.
After turning ignition off and on its ok.


Once it came even without moving a car but after turning the steering wheel. at this time i had dignostic and was looking on data from steering angle sensor but all data looked ok.


Also while driving i cheacked the information of car speed sensor in wheel but till failure came was ok and a second after failure came out it freezed and then ok one more time. But i think that abs sensors are not the problem and freezing cames after failure and not before.
with this failure cames also A/C problem but it does not metter if A/C is on or off. Failure cames all time.


Any one could know what can couse the problem?
Or have something similar?
