Has anyone seen a PTM Failure warning or PSM warnings or know what might cause it? It's happened to me twice in about a month or two now.

first time I was rolling down the hill to the end of my street, maybe at 15mph. Can't remember if the car was in gear or not but sometimes I'll roll down with the car in neutral because it's loud and my neighbors hate me. Car stalled coming to a stop and got the PTM warning message and PSM warning. Scanned the car and cleared the codes and it ran fine after.

happened again for a second time the other day on the autobahn doing about 60 or 70mph. Nothing happened besides the warning, car ran just the same though it also triggers a sport mode failure warning. Scanned car cleared codes and was on my way again.

when I scanned the car with my Accessport I got UC150 and UC202 errors for the AWD system as well as UC150 UC207 and C5400 for Stability and B8004 and UC150 for PAS and B8003 for PCM Gateway (that's a lot of codes)

any ideas?

Unfortunately, the codes returned from Cobb are generic and don't reflect the actual OEM codes. There may be some that translate but good luck figuring that out. This one area where a Durametric could come in handy, otherwise you need access to a PIWIS.

I can't be of any help here but this statement really did make me LOL - we can all relate.

Sorry for the trouble your having. I had the PTM failure on my car - was under CPO. Replaced the module - dealership tried to fix the old module using PIWIS with no luck. Part was under $500 if I recall correctly.
