Customer: replied 3 years ago.

how do i find that info

is has to be read from the car with a diagnostic scan tool. this has not been done?


Customer: replied 3 years ago.

no this has not done



I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.


the first / only step in diagnosing a DSC or ABS fault is to have the faults read from the car and ideally live inputs monitored to determine why the system is cutting in


the system is malfunctioning and intervening when it should not be, but this could be for many possible reasons. Commonly it would be a wheel speed sensor failure or failure of the control unit for the system.


unfortunately a fault scan and real time diagnostic is the only way to gain clarity


Sorry if you were hoping for a different answer, please don't shoot the messenger - I can only give the honest answer, which I have. Please remember that a low rating PUNISHES me for my honest and prompt response, and I receive nothing for my time and answer until a positive rating is clicked.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle

going on from yesterdays contact...The car has been into diagnostic centre and the car computer has been reset after faults read....3 faults: glow plugs, headlight bulb and rear brake pads which were replace 12 weeks ago along with new sensor. when car is moving and orange triangle starts to flash the test equipment loses contact from the car at that point

this suggests a possible module fault to me.



you will need to be sure that full blown factory BMW diagnostic equipment is being used for this diagnosis

The vehicle has been re-diagnosed by updated system. The NSR wheel was reporting that it was spinning 15-20 mph more than the other wheels. The Wheel speed sensor was faulty and was replaced.


Thanks for you efforts................will use again.
