[Biturbos4] Hereditary Audi Disease?

[Keman]

This happens all the time...

My '01 had it happen arond 50k miles, and when it got cold, it got bad.

It's three torx screws behind the glove box and it'll come right out. At
least it was on my model. This seems to be a standard with other audi's
I've seen though.

I took my motor apart, used Caig Laboratories "De-Oxit" D5 (the pink can)
on the copper brush terminals, since they are the source of the noise and
not the bearings. With a few shots of that and a gentle wipe to get rid of
all the accumulated oxidized copper and gunk, I had the brush terminals
looking shiny and new.

After that, I applied some pink synthetic Mobil 1 HD bearing grease onto
the bearings. When I was done, the motor was as good as new, and when I
sold the car nearly 50k miles later, it was still dead quiet.

Sure beat the $150 or $180 or so that it would have cost to replace. Only
took about 2 hours all said and done.

I did use a 1/4" ratchet on the torx screws, as that was the only way I
could get my hand up there to remove them, a screwdriver would not have
fit.
