Thanks for you replacement guide. What trouble codes did you get to lead you to replace the O2 sensors?

I thought you could replace it in 1 min 🤣

Can a bad cat cause fuel cut off codes???i got a 330ci 01 manual... I done replaced sparks, coils, cam shaft sensors, the two o2 sensors on top of the exhaust, fuel injectors, MAF sensor, ignition coils and ignition coil harness wiring upper and lower intake boot, I THINK I fixed all the vacuum hoses they were all busted and torn and not connected, even replaced the fuel pump, crankshaft sensor... Cleaned the icv... Cleaned the throttle body.. idk what to do it's misfiring in cylinder 1,2 and 5.. codes are p1341, p1343 and p1351 misfire with fuel cut off.... The engine is lurching... Hard to start up too... I know I have a battery that needs to be replaced it's from 2017... Voltage has been low not sure if that'll cause the issues I'm having... I've replaced more then this as well lol. Radiator and hoses. Clutch. Alot. But anyways yeah help me.... Only thing I haven't replaced yet is the fuel filter... Also when I give my car a full tank to the max the gauge is off by like an inch or so. Or half an inch.. could a bad fuel sending unit cause the codes and issue I'm having as well? Fuel regulator.. ? Anything. Help me. I haven't replaced the post cat sensor yet though I have them just haven't installed them yet...

Hi Hope thank you for your comments. I don't think a bad cat would matter. However, you correctly replaced the O2 sensors, the two on the top (before the cat,) so I think there's no faulty parts in the exhaust system. But be sure to reset the adaptation with your diagnostic tool so the engine can run with correct air-fuel mixture. I've checked those three fault codes and they are indeed misfire of multiple cylinders. I suspect not only cyl. 1,2 and 5 are misfiring but also the others are misfiring randomly. I heard that an unhealthy battery can also lead to misfire. So please use a new battery for trouble shooting. Check all wiring connections and grounding points around the engine to ensure the electrical system is intact. I don't think the fuel matters a lot. You can go ahead to replace the fuel filter if you suspect poor quality of the fuel. Just to rule out most of the possible causes. I believe your are very close to the answer! Best luck! Carl

530d ?

Hello I just checked the O2 sensor for E60 520d, there's only one. The other two are temperature sensors. Is this the one you are looking for?
