For how many of those miles were you the owner?

compression/leakdown test will give you the answer

You shouldn't have a problem, as long as the car was treated well it whole life then you should be fine. If worst comes to worst you could eventually just rebuild the motor and run one of the quickiest A4's around [:D] [up]

how do you test the compression on the motor?

I always say, thats like a woman giving birth at 45, there a certain chance the kid will come out retarded.

older motor=more reason to replace stuff[:D] [up]

just think of it as replacing an old turbo for preventive maintenance. the stock one is sure to go some time.[:)]

if you want a much more accurate understanding of engine health use leak down testing. I have seen bad motors with "good compression"

well good compression, bad leakdown is most certainly ringwear that is masked when there is oil. i forgot what it means but i think its the first ringland is gone but the 2nd and oil rings are keeping compression when the oil is present on a low pressure compression test. a leakdown more accurately simulates true compression pressures. if that made no sense it's 2am

i would do it. Worst case scenerio your motor is shot and you replace it. and you can find a motor with low miles for around a grand these days

i had always planned on buying a spare engine to play with. if the BT ever popped the engine i would swap in the project block.
