Call VWoA to get this straightened out. There should be a 1 year warranty on all service performed. If you took it there for that problem and they did not catch it, then it should be on them.In spring 2007 (Mother's Day), my 2005.5 TDI manual transmission would not start. Towed to local dealer (NOT who I bought it from), who worked on it for three days and replaced several components saying that there was a wiring issue that "shorted out" several components.
Several months later (September) it wouldn't start again. It turned out that the whole wiring harness needed to be replaced. After several b & m calls to Customer Service, VW paid for the harness, I had to pay for the labor. Their part about $350, my part about $1160. It was out of warranty due to miles (I put almost 48k in 2 years).
I love my Jetta, but this really hurt. I felt that, even though it was out of warranty, it is NOT reasonable to expect that the wiring harness would fail in the lifetime of a vehicle. I'm posting this message to make others aware of the problem.[teacher]
