I'm pretty sure the O2 sensor is bad on my sister's 05 R53. The car has about 110k miles on it, Is it hard to replace? Something that could be easily done at Shop Day? :)

Let me know! Thanks,

Hilary :elec:

It's fairly easy, just unscrew and reinstall, then plug the wires back in.....be sure to buy the correct one, not a generic.....
