maybe just maybe I get lucky?

My local shop gave me a technical bulletin that applies to Passat, 2000-2001, 2.8L vehicles. The OBD for the catalytic converter system may be set too sensitive causing fault codes with out a defect in the catalytic system. The bulletin covers DTC codes P0420, P0421, P0422, P0430, P0431, P0432. The code descriptions all contain an 'efficiency below threshold' comment. Warranty claims would reference 'As per technical bulletin 2010372'. I think that the emissions coverage has expired, so it should be interesting to see if I have to pay for the update. I had the independent shop verify that the 02 sensors are good, and they didn't recommend replacing the cat's before having the code update. Will see how it plays out, but thought folks might appreciate knowing that there is a TB out for, at least, this model year/engine.

since my emission values are all perfect...
