PSM Failure WorkShop 2003 Cayenne S

[Adriano001]

Hi

today the PSM Failure workshop with the picture of its symbol came out and the car is "heavy" when accelerating, even with my foot all the way down the car wouldnt accelerate the way it should, it feels like i am towing a huge motorhome.

i am not sure it has something to do with this but i recently had my Alternator replaced, which to be honest the guy didnt to a good job.   the car wasnt the same after that,  specially electrical parts like locking, windows, engine start (i have to swing the key left and right a few times in order to get the panel light to turn on).

and when he replaced the alternator, the day i got the car, driving home the belt snapped and belt tensioner broke (either it was already broken or he broke when he replaced the alternator).

 

any thoughts on why i am losing power?

 

thanks

My 02 had the same thing.  I had to take to the shop.  They checked for water damage and determined the PSM controller failed.  Basically the car is in limp mode.
