I have the same problem, "PCC shut down engine"

Eek. Can you shut the engine off for and go grab a bite to eat for say 25minutes? That should give the car enough time to reset everything. Sometimes if you yank the car, misshift, or just jarr it in someway it doesn't like, it can give you errors and try to protect itself. Letting it reset usually fixes most issues like that.

I haven't had that error before myself, but hope it's just what I suggest above. Please let us know how it works out, and sorry to hear about the trouble.

I had the same problem. The car would go through all 3 suspension settings but give me the same Error code after one fast turn. It was a sensor. Had to have dealer fix it.

This happened to me the other day on a bumpy section of New York City highway. The exclamation point warning light stayed on for a while. When it went off, I tried to switch to sport and the car turned off "active" and went into auto trany mode. After a quick shutoff it reset. At the dealer now to see what happened. Hopefully all is ok as I just hit the warranty "dead zone".

Aye, let us know how it turns out and the damage. If it's just a sensor, I'm curious how costly it will be out of warranty. Hopefully cheap (actually, hopefully it's just a software hiccup).

Excellent advice. Thanks for forwarding this info. Haven't had this experience on my '12 12C but know what to do now should this happen.

Mine does this on every start up in the cold. It's most likely a sensor issue. Was told the tech it's usually related to the power steering. It will disable you from using the Active function, hence Normal/Normal mode.

Mine goes away after 5-10 minutes of driving and stays off unless the car sits for a while. If you press the Active button while PCC Degraded Error is on, it will most likely stay on the screen and never fix itself. If it occurs, it's best to just drive the car until it goes off before attempting to go back into Active mode.

Well, that's my experience with it at least. I suppose one could have an actual problem rather than just a sensor error. Best to have it looked at I guess. Chance are though that if it goes away with a little driving, it's just a sensor error.

My 650s has developed a "PCC shut down engine" error . It comes and goes and does not leave any trace in the error log. Does anyone know what it could be? I have reported it to the dealer.
