I bought my wife an 04 Jetta Tdi for her 100mi round trip commute. It's all stock, auto w/120k. So far so good. She loves it. Car gets 44-43mpg almost always. Kerma recommended Schaeffer's 5-40 so it got the nod & getting ready to send in first UOA. Also Kerma rep said that the tiptronic autos were actually a pretty good/stout trans which Porche helped design. IDK We have had it just long enough to change fluids,filters,do tires (Bridgestone Ecopias) delete the muffler, and drive the wheels off of it. (Side note: Funny thing about the muffler. It aparently did nothing, was heavy, and took up a shart load of room doing it. Exhaust tone changed almost inaudibly when it was removed and replaced with a piece strait pipe & a turndown. Little things like LRR tires make a marked improvement in fuel economy with these little babies. Also I've heard it mentioned more than a few times over on the tdi clubs that the factory air filtration/intake system is more than capable of keeping up with a modded TDI). Also other than visual inspection I my understanding is that the best way to tell if your cam is going is regular UOA's and keeping a close eye on mileage. Mileage goes to heck= Order cam :Cheer:
