CV joint went about 2 weeks after buying the car, dealership repaired. (which took 4 days!)
Oil sludge started @ 80K. I believe the dealership patched this problem up just enough to get it sold, as I bought it as wholesale.
Car left me stranded on the side of the road with my 2 young children at least 5 times.
Turbo went at 99K, had to have that replaced. VW charges over $1200 just for the part, I got one off Ebay for $300. Took my husband and father 4 hours to take off and replace because of the poorly placed bolts.
Sludge problem original price was $3500. Refused repair, kept driving the car and ignored the light (was not aware that this was a common problem at the time).
About 6 months later it started knocking and lost power on the interstate. Took it to another VW dealer and they said I needed a new engine... $8200 repair. Again I declined repair. Had my father and husband flush the car out and change oil, oil pump, and clean away sludge from the oil screen.
Car ran fine for a few weeks, now the oil light is back on. Cams are grinding and the light only comes on during town trips or after idling for a few minutes. Does not come on while on highway trips or at higher RPMs. Will be trading this car off, or since it is financed through VW themselves, I may just quite paying the payments and let them repo it. They can have it!!
