Hi all.
So I have been having many issues with my o2 sensors. Replaced all 4 with not cheap but not oem ones. They worked for a bit then had a bmw indy sort my ccv out. Car was working fine for a few days then eml popped up. Replaced the pre cat o2's with bosch, reset adaptations then realised Lambdaintergrator 2 was not moving so I replaced post cats with Bosch. I then reset my lambda adaptations and I've noticed lambdaintergrator 2 going up to +28.00 then eml comes, giving me the error code 151 (see below) then goes back down to 0 and sits there.
The error code of '151 lambda probe voltage upstrem sensor 2' - this is a double negative.. It's saying upstrem so pre cat then sensor 2 which is post cat.
I'm so lost now, I don't know what to do. Any ideas?
