I have a 2006 jetta tdi with 96000 miles on it. I did love it until I went to have the timing belt changed and the mechanic told me that my cam was wore(which I used lubro moly 505 01 5w 30) and that my DMF was starting to go out. I'm so disgusted with vw for putting out a product that needs this much work. If I went to 5w 40 oil do you think I could get by without changing the cam? How about the DMF? If I repair all of this I would sink 4000 to $5000 in it. What would you guys do.
