My "not particularly cherished" in the past 2004 TDI 100 AVB engine just hit 250,000 miles today! Proud of the old girl. I've not actually had it long but I know the previous 2 owners. I know there are many out there with 300k but I'm very pleased with this for now! I've spent a fair bit of time ironing out the non-serious niggles with aircon, interior etc but the engine never misses a beat!
