When I went to pick up my car there was a warning on the dash about low fuel. Funny, I thought I brought it in with plenty of fuel. For some reason my first thought was someone had taken the car for a joy ride, but their were many PDR's so I thought I'd go get gas first and then scrutinize the PDR's. Start pumping fuel and it only took 4 liters! Hmm, that's odd. OK, the dealer forgot to hook something up. (Yes, fumes were coming out of my ears.) Get back in the car, start it up and it now shows full and has been fine ever since. Makes one wonder what they had to disconnect for the DCT filter replacement.
