Mercedes C32 AMG
All four o2 sensors went out
Hi all, I have a 2002 c32 AMG. 138k miles all maintenance up to date. Basically I went driving last Friday and it was running smooth and doing good, then this week on Thursday I drove that car again and I turn the car on.... and I get ESP says unavailable, I go to take off then I notice supercharger isn’t turning on at all. So I take it to get scanned and I got ALL FOUR 02 sensors bad. I have checked all wiring for any damage and seems to be fine, I reset the entire car, clear the codes. Then turn it back on and boom instantly codes came back. So I started to check fuses and relays. Those are all good. Basically I have done everything but drop $500 for all four O2 sensors. Any ideas on what this could be? Or how to fix this?
