I got a 2010 TDI Jetta SportWagen back in September. Since that time we have had it in the shop 6 separate times because the check engine light keeps coming on. The mechanics have now replaced all 4 fuel injectors, as of two days ago. The check engine light came back on today and we are assuming it is the same problem fault code, fuel injector failure. The mechanics called the VW tech in Denver to consult on the problem and he said that it is possible that we are the victims of bad Diesel that keeps tripping our check engine light for an injector failure.
I doubt that it is bad diesel as my father-in-law has filled up his TDI at the same station for the last 5 years and I have a '00 TDI that I have filled up at the same station for the last 2 years and neither car has had any problem.
Any insight and/or help on this perplexing problem would be greatly appreciated.
