    Default O2 Sensor P1039 Fault

    Evening,

    Just wondering if anyone has had this problem on the R56. Noticed it last night when it flashed up on my Ultraguage so cleared it and never thought much of it as it never happened again, until we were out on the run where it kept coming on, reset it and during a spirited drive it came on after 10 mins but on a steadier drive you could be looking at it coming on 30 mins into a drive and at speeds above 50mph.

    Looking at google it could be a number of things dodgy connection, faulty sensor, and the car pulls like a train so if I never had the scan Guage I would not have noticed. No engine management light either.

    If it’s not bringing up any lights I wouldn’t worry about it to much. Have you checked to make sure the plugs not loose? Is it just a bad box you have changed on your car Davy or is it a full system. Could be picking up a change it flow if it’s a full system.

    Just from the Cat Back System, will keep a eye on it. Had to spend £7 tonight on a replacement headlight access cover as I think I lost one today when i hit a pothole.
