My Passat (99 V6) was in to the dealer for an intermittent cruise control.
They ended up replacing the cruise control switch but then apparently
needed to "perform throttle body adaptation". This operation failed,
despite there being no previous trouble codes related to this component.
So they wanted to replace the throttle body and quoted me $700 to do so. I
refused, with the new symptoms (as described by the mechanic) of hard
shifting and the "engine check" light always on.
Can this "throttle body adaption" be attempted by another dealer service
department with any chance of success? Or am I truly stuck replacing the
throttle body at this point?
Thanks,
Bryan

They prob broke the throttle body replacing the switch and now want you to
pay for it.
Any vw dealer should be able to do the adaptation .

Duh! please explain? There are no cruise control switches mounted on the
throttle housing.

I had the same problem on a V6 A4. The car was working ok but the a Throttle
body adaption needed to be performed. Couldn't communicate with it and a new
Throttle body is required. I got it replaced under warranty thankfully ! It
is a common fault apparently. There are companies that rebuild them.

Followup -- another dealer tried but also could not successfully do the
throttle body adaptation. This is a 7 year old car so I hate to put that
much into replacing this part. Any chance that a used or rebuilt throttle
body could be put on it with success? If an independent shop does that, do
I still need to go back to a dealer to do this adaptation, or should it be
good without?

Buy a remanufactured TB. This place ( http://www.bba-reman.com/ ) does them
but they are UK based. There will be somewhere in your locale I'm sure. It
will need coding to the car and a TPA performed unfortunately. Buy VGA-COM
or find somebody in your area with it.
