I have been having an intermittent problem recently and wondering if you have any ideas?


Its missing under Full Boost at about 3500-4000 rpm. Boost stays at 17-18 psi even with problem, power stops of course. Its for sure missing and timing seems to get off. I have a Stage II APR tune, Full APR exhaust. Otherwise engine runs flawlessly. Even does fine at higher RPMs.
Previously has not thrown a code until just 1 day ago when I stayed in the gas to see if I could blow it up for good! Alas it didn't work, except this time it did throw a code/Check engine light. I do not have a Code Reader. I have had it at dealer, and they had no clue. I changed the plugs and ran injector Cleaner. Did not help. Each time to the dealer they tell me its $120 for nothing! HELP!! I am planning to remove the Tune and see if problem goes away. Could it be a problem with a ignition advancer? Does this motor even have that? I assume there is variable timing?

I had a Older Mitsubishi Starion Turbo that had a hole in the exhaust valve that did the same exact thing! Worrying me!!

Nobody has any ideas? Some are saying switch Coil Packs to the Audi R8 versions. And a Cam Follower? I am not sure what that is actually. Cam Sensor?

Not sure what your problem could be. Go to your local autozone and ask them if they can scan your car for you, or find a local with vagcom. Its a lot easier to diagnose a car if we have codes rather than just shooting in the dark. Also, as an FSI owner, I highly recommend you read up on cam follower and the issues associated with it. If you don't take care of it it can ruin your engine

It was the Coils. I replaced them with New Audi R8 versions. Cost was about $70. And now its for sure more peppy!
