Hi guys ive just reconnected my battery on my 2004 Cayenne and have thhe PSM light on. ive searched the threads and have found the following post, which I will paste below:

"Ok, so I just got done RTFM and it's really not as big a deal as you make it out to be. It states (p.321) after battery is connected you will get a PSM light and can be remedied with a few "simple" steps. Those steps are outlined as well as the window reset. That's it. Nothing to get alarmed about.

But thanks for the heads up so now I know what to do after I reconnect the battery"

OK does anyone know what the simple steps are to get the PSM light off?
Thank You

 

Get in and drive.

 

Ah just read the section in the manual....simples!!

 

Lather, rinse and repeat a few times. Be sure to remotely lock and unlock the doors when doing this as the computer initializes on the unlock/door-open operation.
