I will send you some great OBDII and Vag software to monitor just about everything. Use your Vag-com cable for both . Check you mail.

Will the dealer cover it? It aint cheap.

Exactly what Rick said - problems with the O2 sensor could cause that exact problem - good luck.

It, in itself has caused misfiring after installation. Not all cars like them.

There are no plug wires. There is a coil over each plug.

Fuzzy logic

the sensor is screwed into the MTM downpipes, so I would have to rub thier noses into my mods, a bridge I'm not ready to cross for a $160 part. Plus, they will have to confirm it, and that takes a 45 minute drive at highway speeds, and I do not relish anyone driving my car like that, unless I know them well!

Get the OE part # and buy it from any Bosch dealer for 125 or less..

It does sound like an O2, why not swith bank 1 to 2 and see if problem moves over there.

if platnium plugs were a problem, Audi would not use them as the OE plug... S4's use NGK PFR6Q's...
