07 GTI - had the dealer replace the turbo due to requiring to fix the CEL for end of march PA state emissions inspection. The codes were fuel too lean and underboost. For months now the turbo was noisy at and past 3000 rpms. It was found the shaft and bearing had play in it and that was the cause. Replaced turbo codes went away and passed inspection. Days later the fuel too lean code came back. Had an independent shop do timing belt and replace brake booster cable, codes gone. They noted I had a pending code for underboost and if it comes on they can diagnose it. A day later CEL comes on and I check and its p0299 underboost.
The dealer warranties all parts and labor for 1 year. I can take it there and hopefully it's covered in full. I spent enough on this car in the last few weeks I'm about ready to sell it for something with 4 doors instead of two.
What do you think the underboost is from? Something come loose from the install? They get a faulty part? Trust the dealer or take it back to the independent shop?
Nice loaner cars - don't have to take time off work.
Warrantied parts and labor
Honors Extended warranties (they did my HPFP / cam / follower for free)
Independent German car shop pros:
Closer to home
About half price for everything (timing belt was half price what the dealer quoted).
