Need input / carbon buildup on intake valves
Hi,
I have 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?
Thanks!
