Author Topic: ABS Light On (Read 2865 times)

Hi guys, during starting of my car I saw the ABS light come on and stay on. (Should go out after self-test) Anyways I diagnosed the problem as being a faulty ABS Main Relay. I am wondering do I need to get the fault cleared by BMW or will fitting the new relay clear the light?

Thanks.

As far as I know it will turn its self off when the fault has gone

Happily it's not the airbag, that needs reset by BMW or someone with the right equipment.

Replacing the faulty component will clear the lamp from what I've heard.

I would recommend unplugging the battery when doing this. I know that pulling the airbag with the power connected causes the ABS light to come on & it has to be reset at the dealer. The relay might not have that issue, but you should unplug the battery just to be sure (and safe, always unplug it before electrical work).
