Im replacing a 2006 jetta. Found a 2011 jetta tdi with auto trans. It has 145k miles on it. Its a dsg trans. Its had 3 owners. Looked at carfax. It shows oil changes done regularly, the only repair was for rear brakes. But my 2006 dsg requires 40k trans service which i always did myself with a kit. This surely would show on carfax if done...at least during warranty period. This would have voided the factory warranty if not done, right? Isnt the same 40k service required for the 2011 model?
