Check in over at AudiWorld.com and Audizine.com - there's not a lot of information on the Audi diesels in the USA yet. We're about to see many more small block turbo diesels in the near future but we're not there yet.

it might help if you know what codes were stored in the engine management computer,way too many codes and procedures to even begin to guess.
