Hi,

I just recently acquired a used cvt, low mileage and all...

I've noticed a vibration problem when the car comes to a full stop. The
RPMS tend to drop pretty quicky between 1100 to 800 rpm (when deaccelerating
down to a complete stop) and there is a noticeable vibration kicking in. On
acceleration and at cruising speeds the vibes are no where to be felt and is
smoother than slicing butter.

I did bring the car for a check and they claimed that it had something to do
with the air throttle body which was dirty and prevented the valve from
moving freely. They cleaned that up, and it seem to provide relief for a
short distance of driving, but is clearly back as a problem.

Is this normal ? If it isn't, any ideas of what the problem could be ?

fyi: the ignition coils were replaced supposedly sometime in 2003.

TIA

Audi USA apparently has an extended warranty program for the throttle bodies
on most B5 model A4s. I don't know if this is only for North America. If your
car isn't under an extended factory warranty, start working over the shop
manager to go look for a TSB on the throttle body problem...

I think this warranty extension (7yrs/70K miles) was for MAF, unless
there's another one for throttle body that I'm not aware of. And yes,
it's only for north american models, AFAIK.

Cheers,

Wouldn't a 2002 be a B6? Did they ever offer B5's with the CVT?

You're right - I just checked the snail-mailed notice and it was indeed for
the MAF.

(Which - given how fragile MAFs tend to be is probably a "more likely to pay
off special warranty"!)

'00 s4 6spd, no MAF or TB bugs yet

You may well be right - I don't presume to be aware of all the various flavors
of model years found on different continents, 'cuz every time I do someone
says "Oh, we got that the year earlier in Australia" or some such

Otherwise, it was for the MAF not TB, but otoh, is it possible they use the
same MAF part number on any models of the B6 vintage?

Thanks for all your feedback. I'll try to lean on them to have that part
replaced and hopefully resolve the vibes problem. It seems though that there
is a back log of people on the waiting list to get their audi's serviced,
somewhere in the order of at least 2-3 weeks lead time just to get in, does
make you wonder though.

Thanks again
