Bought CTS-V, Fuel CEL popped in the dealer lot! Just pulled the trigger on an 11' A6 CTS-V. During the test drive, the car definitely felt down on power. For reference I've owned a C7 Z06, 17' SS, cammed f-body etc so I have a decent enough understanding of what roughly 500 whp should feel like and this was definitely not it. Looking around for any weird indications, I notice the boost gauge was at 0 and wasn't even moving. Nothing I could do to the throttle would cause it to move. After driving it for about 10 min, the boost gauge started working and I started the belief cycle of "my butt dyno must be miscalibrated" and that everything was fine. The car is absolutely impeccable everywhere else.
Well, it was not fine and I should've never second guessed the most reliable of performance instruments (Mark IV butt dyno). Upon going to literally pull out of the dealer lot, the car popped a CEL. Had the service guy scan it and he came back and said something something fuel relay. I asked for the code number and mysteriously no one knew what it was and no one wrote it down, they just cleared it out. Thought that was extremely shady because how do you as a professional service department scan a code on a car you sold 5 seconds ago and not know the code number. But I digress. Left the car at the dealer (it's still under 90 day warranty and I technically haven't dropped off the check to them yet since it's the weekend and bank was closed) and they assured me they'd get to the bottom of it. While I don't doubt their intentions, if this is a fuel sending problem that's going to cost big bucks I can 100% see them being like "oh yeah it was the spark plugs we changed them it's all good" or some BS.
Not trying to put the cart before the horse but I've bought enough cars to be able to envision how this is probably going to play out (i.e. it's in their best interest to try and appease me for the littlest amount of money possible to them versus fixing what is most likely a pretty big problem with the car) and I'm just trying to be prepared. Outside of the obvious fuel pump and/or injectors, what are the common fuel issues with these cars? From what I could tell, the car looked bone stock & I don't believe it had a pulley on it. Obviously not to say the previous owner didn't have one on there and swap it back prior to the trade in.
TIA
