Would appreciate some feedback!

Got an '08 A4 / 3.2 / quattro with only 7k miles. On my way home from pickup at the dealer's shop doing a 7500 mile maintenance (essentially an oil change!), I got a "check engine" light. After a week of diagnosis, they tell me it's due to excessive carbon buildup on the intake valves and need to replace the injectors.

Is this at all possible on a new car which has had only good gas used in it? Is it possible the dealer could've done something to cause this?

 

listen, if it looks like a rat, and smells like a rat.....it prolly is a rat. your car has less then 10 k on it and if ur saying u put nothing but premium in your tank then theres no way there should be excessive carbon build up on your car...and if there some how is....a fuel injector cleaner would be a good try first then the dealership

 

or if you would rather not do this, go to the dealership and ask them if this is normally covered under warranty, and if so let them deal with it, if not try the fuel injector cleaner and if its still on then go back. but seeing as you only have less than 10k it is still under the normal warranty

 

Yeah thats B.S you got a lemon..
