Fault code not in manual

I had a fault code appear on the dash today: GRA/ACC fault - driving permitted.
However, it didn't re-appear on the return trip home.

Can't seem to find it in the handbook.

Any ideas?

Thanks Jeff.

I did catch the cruise control talk in a strange way. Seems to be innocuous and non-recurring.
I was getting anxious when i saw the talk of engine flushes being required given previous travails with my old macan s.

I was about to sell the macan turbo and get a 991.2 turbo and a sportage!

I think that if the problem persists David a trip to the dealer will be required to get a PIWIS diagnostic test performed. Hopefully it was just a one-off.

Hi, I also got same error message today (GRA/ACC fault); my car is less than 2 months old with about 2.5k miles. I am currently on a trip back to Rutland from Northern Ireland, I called my dealer who told me the earliest they can look at it is 11th August and recommended that I call Porsche Assistance for advice!
I’ll keep the forum updated on progress.



 
I've had a few transitory error messages occur over the last 19k miles, those from the ACC have generally been in the wet or when the car was due a wash. None have persisted long or been worried about, although I'm still curious about what might trigger the front ParkAssist when stationary and "socially distanced"!
 
Maybe, I'll take note next time. Could easily be interference similar to when my wireless doorbell used to chime when a neighbour used their remote garage opener. I decided against speccing the surround view after getting fed up with it getting over excited on a test drive when passing parked cars in pretty normal width streets!
 
Update: I parked and turned off the car for a couple of hours (I drove onto a ferry so couldn't go anywhere anyway [:)]) ... when I restarted the error code was gone and hasn't returned; I won't be taking to the dealers on August 11th.
