Fault - ACC Not Available error message displayed

**SHANEO79** · 01-01-2020, 09:50 PM

Hi guys

Happy New Year!

Twice over the last three weeks I have started up my Arteon, engaged drive and taken off at slow speeds when suddenly the car shudders, the gearbox feels and sounds like it disengages then a very brief warning appears on the dash "ACC Not Available" in orange. Then after probably 3 seconds everything clears and the car returns to normal and I can drive off.

The first time this happened I was pulling out of a parking spot on the side of a flat road and when it happened again tonight I was pulling out of a shopping centre car park onto a main road.

It's a good thing that on both occasions there was zero traffic on the street or approaching from behind as with my car coming to a complete stop when the fault occurs could have been far more interesting if someone was behind me at that time.

Anyone here experienced this in their VW?

Thanks.

Shane

Another forum site shows others who have had the same problem.

VWVortex.com - ACC not available!

Guess it's time for dealer.

Thanks for the headsup Ando, I'll head over there and check that out.

Hey Shane, yep mine Has done the same three times too. Am working with the dealer to bottom it out. So far it’s had the gearbox software updated but it’s happened again once since then. I’m meeting with their diagnostic guru next week to discuss the plan of attack.

Thanks JVM, I appreciate the info. Would you mind posting another update when you get to the bottom of this issue? I'm still 10k away from the 30k service so It'll be a while before I get the VW team to check this out.

You don't need to wait for a service schedule to get a team to look at issues. I've brought my car to the dealer many times, no matter how small the issue.

I haven't had chance to catch up with the diagnostic guy yet. I get on well with the service team (My son has even done work experience there) so they are keen to dig into it and see what they can find but I just haven't had the time to call in. Will update when I do get in there.

Reading everyone's posts, the faults all seem identical and unfortunately don't record anything in the fault logs so I suggest recording all the details and report it each time so if it degrades over time, there is a history (especially important as you get close to the end of the warranty period)

Hi JVM, thanks for the update.

I'm off to my local dealer Monday week so at least I can get this recorded and noted on file for the future as a solution might be a little while away.

I'll keep you posted.

Will do.
Incidentally I don't believe the ACC has an issue. Many cars disable the cruise control when a fault happens and I reckon this is the case here. If I'm correct, the "ACC not available" warning is a consequence of the gearbox issue and not connected.

This happened to me 3 times in the space of a month when I first got my Arteon. All 3 times were in similar circumstances, where I was driving slowly up hill or a car park ramp. Reported it to dealer, they performed a dsg update and I have not had a issue since (over 7 months).
