So driving home today I had the following appear:
AWD fault, only rear wheel drive
ABS/PSM failure
Parking Brake fault
Suspension system fault
ACC/PAS unavailable

Any ideas anyone?

One of the four speed sensors may have gone AWOL. Your OPC or indie should be able to diagnose quickly. It’s a simple replacement.

Super. That's what my Porsche Dealer suggested was the likely cause.

After switching off, exiting and locking the car are the faults still showing the next time you drive it?

I have had that a couple of times and the faults clear.

Not had to have a sensor replaced (yet).

I have tried that twice now but it still keeps returning. Recovery on the way now!

Had exactly the same thing happen 2 weeks ago. It’s usually one of the ABS speed sensors but Porsche insist on replacing all 4. If under warranty it will be covered by Porsche.
