@joni, if I understand correctly from the thread you have an MG downpipe and stock back box, right? Did the EML ever come back after you’ve connected the rear sensor properly?You may be right as I took my back box off and drove it around to see what it was like and there was no EML on when we did this.
the EML comes on intermittently and either goes off by itself or when I clear the fault code
Sorry been offline for a while. EML didn’t appear for close to two months then appeared but I just cleared it. Been about two weeks and its not come on. Haven’t had the car remapped yet - still in two minds. Sounds awesome though the exhaust has gotten louder.
