98-01 4cyl turbo engines

[Alex Cagann]

Engines were all stock with normal maintenance performed.  The last one had
right at 100k on it. Two of them went with mileage in the 70's.

I haven't heard anything about these engines being prone to 'blowing up'. I
guess I would ask first, were these all unmodified engines? I.e., no cold
air intakes, chips, larger turbos, changed intercoolers, etc? Was the
maintenance done timely? Oil changes, timing belts/tensioners changed? What
were their driving habits? What kind of mileage on the engines?

Audi HAS changed the maintenance schedule on these engines, recommending
synthetic oil and a larger oil filter and the first change at 5k miles
versus 10k.
