:banghead:Hi

i got a problem with my 2001 m3 100 000 miles. Each time i brake, when i am at +-20 miles/h , the system abs locks my brakes. Once i restart from the stop, the systeme abs comes off.

someones have an idea? I got no light in my dash!

Sounds like a bad ABS sensor or modulator to me, but that's a straight up guess

yeah that what i think too, but yesterdays, i clean all my sensor like this http://www.pgautosale.com/servlet/the-938/34521164651,-ALS447,-5S10513,-SU11966,/Detail

Where is the ABS sensor, i can't find it

The abs sensor are the wheel speed sensors, The modulator/ abs unit is the is the box with like 5 metal brake lines going into it. either located in the rear passenger side or on the rear driver side by master cylinder on models (03+)

Yeah oK! , i see it, my modulator never dit that before, i just swap my 4 brake ( sensor(use) big brake, and pad, and after , my system abs do this trouble. I got 4 abs sensor in my house , ill try to change it and see if there the problem goes out.

So my probleme can be only modular or abs sensor??

Hows the brake pedal feel may need to bleed them with abs actuating with either a gt1/ other bmw equipment.

the brake feel good!, when i drive, it's like normal car, excep when i brake at +- 5 miles/h until 0 then the Abs unlock, and i can restart normally
