my 325i abs light is on...its been on since i bought the car, also he low brake pad light... brake pad are fine though..ive checked the wiring and all looks ok.. the light is off when you first start the car but comes on minute you set off... anyone had this fault before

Most likely sencer related sine it goes out when you start the car then comes on when you move off.

Probably one of the wheel sencers not giving a correct reading. Have ou got a multimeter? If you have there is a documented way of testing them from withing the car.

Definately sounds like a sensor. Check the resistances with a multimeter at the sensor multipplug. You may find an open circuit if so replace. If not go on to millivolts and rotate the wheel you shoul find a nice gradual rise. If not then replace the sensor. If all ok then it could be a break in the wiring going to the ecu, unfortunately havent got any technical data at home but i'll try and dig it out at work tomorrow.

ps have a look to make sure all the abs slip rings are intake or even there, had that before where people have left them off or fitted incorrect parts with no rings. As regards the brake warning light probably loom fault or dodgy pad wear sensor. Once again if you have an open circuit at the sensor then its a dud.

cheers guys...ill hey a look and investiagte this weekend
