[BiturboS4] Todd from AWE

[j y]

john,

Are u telling me that a stock S4 (with 52.9k mi)
drvien at 75 mph on a major highway that has turbo
failure (in my case - preliminary diagnosis by Audi
dealership is compressor failure) is the driver's
fault?

Sorry...but I find that to be a stretch.

If you are talking about CHIPPED cars that are
TRACKED, or driven aggressively on the STREET, then I
would be inclined to agree with your position.

It's NOT ALWAYS the DRIVERS.

Like everything else in life - u have to take the
surrounding circumstances into account.
