    Hi,

    I recently encountered a problem whilst driving and my local garage cannot find the exact fault- can anyone out there help?!

    I have a 1 series 120 petrol 54 plate. Driving at 60mph, I suddenly lost power with the Dynamic Stability Control light flashing on for a split second. The car was 'juddering' and wouldn't accelerate. This soon rectified itself and seemed to be ok again.

    After 1 week with no problems, the same thing happened again, and again AND AGAIN!

    The diagnostic isn't reporting any faults whatsoever so its hard to find the exact cause.

    I have been told this may be sensor related..?

    Any advice is greatly appreciated- thanks in advance! :-/

    It sounds like one of the rear wheel speed sensors is sending a spurious speed signal out which is causing the traction control to cut power. Sometimes the reluctor rings on the drive shafts can corrode between the shaft and ring causing them to distort and wear the end of the sensor off. It then sends out spurious speed signals.

    Thanks for the reply- you've hit the nail on the head. I've pieces together what has happened and car should be fixed tomorrow. I had a flat tyre 2 months ago... After being replaced, I never reset the tyre pressure indicator (lazy I know.) When I finally did, the problems started occurring the next day. I've just been told to hold the DTC button down for 5 secs and drive the car. This stopped the juddering completely until I reverted back to having the DSC back on.

    I'm having the sensor replaced tomorrow and all should be ok.

    Thanks again for your post, this enabled my mechanic to understand the problem better.

    Hi I am having the same problem with my 3 series e90 model. Can I ask what sensor you changed and did it stop the issue?
