Hi all I have a 54 plate 2.0L diesel x3, a few weeks ago I had warning lights on the dash, plugged in a reader and got rear right sensor fault, so I changed the sensor and cleaned the sensor ring, fault cleared after a few times of resetting, so gave driven the car for a few days all good, now I have the same fault lights on the dash so stop the car turn off restart fault gone drive some more and at different times the fault comes back, now reads rear right sensor air gap, can any of you recommend a fix
Thanks
John

Morning John

From your description we are talking about the the ABS sensor and reluctor ring? When you say you cleaned the ring was it badly corroded? If to much surface came away while cleaning it could give an un-even air gap? Also is the new sensor seated properly and torqued to 8 n/m? I have also read that the ABS unit can throw these faults 

Sorry no solution but my thoughts 

Dave

Check www.newtis.info there may be something for your model there as it is the same technical information used by BMW Dealers

      Rough idle problem

      Hello Dave, Just an update and I think you may be right. Went out and gave it a few revs when cold, nothing. Let it warm up and there was a loud “shoooo”. I’ve attached a photo of where the sound was coming from. Going to get it looked into but do you have any idea of what it could be? First BMW, always had vag cars so engine are a little different to what I’m used to

      Rough idle problem

      Hello Dave thanks for your reply, thanks for the reply and it does sound like that could be the problem. I was thinking injector but never pops an engine light up so wasn’t certain. Was serviced 6500 miles ago but was just oil and filters. Going to check later and see if I can see any visible cracks or splits. Got a friend who has a garage and will obd and smoke test it for me.

      E53 petrol fail safe again.

      Morning Stu Long time since I played with a straight six so the old memory might be wonky here so check realoem From memory it is linked to the Air Pump and Vacuum control system. Find the Airpump and follow the Vac lines to the rear of the engine you should find a valve with a plug on top (or end) first make sure all lines are good no splits or cracks check the valve is operating, dont forget there is a non return vale in the system close to the inlet manifold. Hope this helps Dave

      Water leak at sharkfin aerial

      Morning Vic New one to me but I guess anywhere there is a joint is suspect. Like the seals around the rear lights that suddenly start to leak, removing them a good clean and renewing the seals seems to work. Check www.realoem.com to see what is fitted and how Dave

      Rough idle problem

      Morning Billy When was the car last serviced ? The symptoms you describe could be due to an air or vacuum leak, old hoses seals and vacuum lines can start to crack when cold they are stiff and don't leak (as much) when hot and flexible you see the issue developing. Your OBD Scanner needs to be BMW capable a standard scanner will only see critical functions. Dave
