Has anyone changed the upstream and downstream 02 sensors on a 2006 mercedes Benz c230 sport
Yes. Why do you ask?
I need to change mine but cannot figure out how to, I did the down stream ones easy enough, but the up stream seem to be bothersome do I need to drop the exhausts ?
No need to do that. There's a tool made for removing O2 sensors. AutoZone, Advanced Auto Parts any place like that. Runs about $10.00
Cheers I shall give it ago
