Give it a little time. I had a pretty potent vinegar smell for a
while when I replaced mine from the same sealant stuff that goes
around the core. Took about a week or so and was gone.
So don't panic...yet. :)
As to the turbos, for these cars they can be found really easily if
you're so inclined. You can get turbos from the 92-95 S4/S6 to
replace the turbo on the 200. I did that and no problem. Just put a
"wanted ad" in the list classifieds. You'll be amazed at the volume
of responses. Also by looking for those other cars as source, you're
more likely to get a turbo that has lower mileage. What to look
for? I'd say bascially mileage, but would also wonder what is
prompting you to want to change the turbo? As I found out, in
general they are pretty damn robust.
If you do go for the change, look for a post I sent to the list a
couple of months back. Sent in my learned wisdom from the same job.
Basically easy with a couple spots that are a bit of a pia.
