Default O2 sensor ? Drivers side bank one has been bad for sometime. Had it replaced today and the car seems
to have a lot more acceleration. Feels less laggy. Will a bad O2 sensor make that much of a difference?

Gotta use the correct DOT formulation though. Makes a HUGE difference in performance

Default In my case, I replaced all 4 and now my car runs crappier than ever. The new O2s made my EGTs go bad
Not. They were already fried. More money to spend. Yay!

Default Should always replace O2 sensors in pairs (min).
I had persisent codes from my B2S1 and replaced both primaries.

Default What did it cost to have it replaced. Mines been throwing a code for a while...
but it says that there's no connection to the O2 sensor in VAG. Which would make me think a wiring problem but I can't find anything wrong with the wiring.
