I have just unfortunately bought a lemon from a trader, It's my fault I guess for trusting the guy.
very expensive mistake, Audi A6 3.0tdi smoking at idle, interestingly it was bought as a cat D which i believe are always understood to be spares or repair, ie no warranty,
Gutted as it's going to cost me thousands as I can't and won't lie.
put me completely off VAG products,
Have spoke to 2 mechanics and a dealer also VAG owning friends, seems that VAG reliability especially the diesels is a myth
