o2 sensor stuck!! Can't remove it! - BMW Forum

seems to be corroded to my exhaust/cat

tried wd 40, with a proper lambda sensor socket and a power bar and it still won't budge.

any idea how i can get it off??

Did you try heating it? Before you do that though, try soaking it in wd40 and tap the o2 sensor a few times. The vibration caused by the tapping will make the wd40 seep in between the sensor and the exhaust. Good Luck

Yeah, try running your can for a bit to heat it up. I had to do the same thing.

Thanks peeps,

ran the engine for 30 mins before trying again this morning. Still didn't budge, so we got the blow torch on it.

Came off piece of piss!

thanks!!!

I had the same problem, It's best with 2 people and taking the cat off. That's how I did it cuz it wouldn't budge.
