Thanks dave, I have spoken to a couple of garages and the recommended changing the drive shaft and sensor

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
