so I bought a 15 4.0 on Saturday with 20k on the odo.
day after I bought it - no joke - epc, cel and rev limited. I’d done 6 miles.
it’s been at the dealer and after longer than I’d have wished they say it’s a camshaft actuator.
parts on order...

So was I unlucky, or is this a common problem?
Are there any other gotchas? It’s a used Audi. I expected electrical issues, not engine problems...

Allzwell

Not a good way to start.
I'm just at one year into my first Audi product and can't say that I'm that impressed with the quality of the car.
I'm fortunate that mine have been small things but I've probably been at the dealer as much with this car as I was with my last BMW's so I'm not sure what badge will be in the garage next.

I've got a 2015 A8 4.0T as well - camshaft actuator does not seem to be a common problem. The notable things that have surfaced for these cars is the 3K RPM engine vibration (fixed with replacement of downpipes under warranty) and maybe the suspension bushings/sway bar links. I've had my car for a year - bought w/ 29,500 miles now at 48,000 miles - with no issues except for the downpipes, which the dealer replaced with no drama.

I broke rule #1. Never ever ever under any circumstances buy a used Audi. Now I'm paying for it.

I expected electrical issues - I mean they are famous for it - but this wasn't anything I'd considered.
I've only ever had two cars with engine issues. Both bought used. Both VAG. Both camshaft related (bolts on the VR6 backing out was the other).
Hmm - maybe there's a pattern emerging.

So I got it back this evening.
