After much reading of the forum lately was slightly concerned after reading of a few reports of members beloved 2.5tdi engine letting go with what I would consider relatively lowish miles (100/150thou). Yes I know there will be over abused cars and this would be quite normal to hear of engines going "basket case"! My B6 2.5 tdi sport now has 140 thou behind her now and was bought with a full Audi service. I have kept on top of my services and have received excellent reliability. So my question to members with the 2.5tdi engine is who's got the biggest mileage on the original engine. Hoping there are some big milers out there considering the 1.9tdi's can easily with care get to the quarter million mark.
