 When my 2006 Jetta TDI had 42,000 miles a timing belt clip broke at 45 mph, and after a loud "clang" the engine locked up.
 I requested a new engine, but VW refused and instead repaired the existing engine with a new camshaft for cylinder #1.
 Since then two more camshafts have failed for cylinder #1.
 The vehicle suddenly lost power in front of a semi tractor trailer at 65 mph and my family was almost killed.
 Absolute lemon.  VW Customer Care Center doesn't care.  Period.
