I just changed out my O2 sensors on my 2002 540. Does anyone need a set of known good O2 sensors, 88k miles? These have never thrown a code, just changed them out because of PM.
2002 540 6 speed, Steel Blue/Black interior, totally loaded with every option, and now with built in Stealth One/Valentine 1. 18" Staggered Privat wheels. I am loving the power again!
