Thought I'd make people aware of what is possibly a looming issue. I've had my X3 from new since March 2016 and it's done nearly 14000 miles of mostly very steady motorway driving. For the past couple of months I've had an intermittent error message popping up telling me of a 'drivetrain fault' The error was cleared straightaway, didn't show in the check control option and there was no problem with the engine output at all. Last Sunday the error message popped up and this time it stayed and the car went into limp mode.
I telephoned the BMW Emergency Service who told me to take it to my local dealer and I would be given a hire car whilst it was repaired. I took it to the dealer who told me straightaway after plugging my key into their system that it was a problem with the exhaust gas recirculation valve. Next day I received another call telling me the part was on back order and they could give me now estimate as to when the part would be available. I received another call last Friday telling me the part is still on back order, no date could be given for it to be fixed and that BMW would continue to pay for the hire car I was given. I was told that the part has had to be redesigned and that they currently have three vehicles in all with the same problem, 2 are 16 plate and one is a 64 plate. In the meantime I've now been without my 11 month old car for a week and there is no prospect of it being fixed.
