Default Worst it could do is catch fire and burn off.
I give it the go ahead(not responsible for any outcome).

I ended up using a small propane torch to heat up the O2 sensor on a MB 300TE wagon I used to have. It broke free after that. Was a PITA without the heat (didn't want to move even with a four foot pipe!). Probably could have just ran the car for a while and let the exhaust pipe heat up. Audi A4 has the first O2 sensor on the exhaust manifold, so should be the same proceedure other than not having to crawl under the car. :-)
