Has anyone threw a P219E code before

I did a search and didn't come up with any posts but just wondered if anyone has seen this code before. I took the car to a mechanic in town to read the code for me, it came up but he couldn't find anything on it and through my searches online all I have found is "Cylinder 3 Air/Fuel ration imbalance" and when I called the dealer thats all they could tell me without scanning the car themselves. All and all the car seems to be driving just fine as far as I can tell, but I'm not sure if I want to clear the code and see if it comes back or leave it in and take it to the dealer. Secondly I'm guessing I should probably put the stock intake back on before I take it to the dealer, curently running the CTS intake. Timing on this couldn't have happened any better I guess, I was a day away from flashing Stage 1 but thats on hold now for warrenty sake until this is resolved. Car only has 35,000kms and has been great up till this code.

From what I found searching it may need a tune up or have carbon build up. Not much out there on that code

Yeah I know I can't find any additional info either. I guess I will book it into the dealership sometime over the holidays and have them check it out, still have warrenty till next october and haven't yet flashed my EPL tune, so that might have to wait a little longer. Damn

Yeah, I'd leave the CEL on so they can scan it themselves and see it and again, yes, just wait a little on the tune to get this straightened out especially since if it needs plugs or a carbon clean (not saying it definitely does), but that's not going to be too cheap so it'll be worth it if its going to be covered.

So took the car a holiday road trip and shortly after I filled up with a new tank of gas the light went out on its own. Guess I don't need to take it to Audi after all. The light had come on 50 Kms after I put the old tank in, could this have all been from a bad tank of gas? I put ultra 94 in then threw the code and went back to pioneer 91 and code went away. I think I'm going to write this off as bad gas but to be safe I'll probably call Audi to see what they say.

Just in case anyone else runs into this code, just got back from the dealership and I guess I had an injector sticking some what closed while the code was on and now it is appearently opening and closing fine now, with the code gone. The dealership is going to replace the injector under warrenty, which was great timing for me. I guess stage 1 can wait a couple more days.
