Hi there. I'm a former jetta owner and in the market for another one. I'm looking at a 2005 (new body style) TDI jetta. The car had 210000 miles and owner says it has worn cam lobe. Currently drivable. My question is what Is that and how much to fix myself. I don't like repair shops because I don't simply trust them. I can get the car for a really low price just need to k ow if it's worth the time and money to fix. Thanks in advance.
