    ABS light on, MOT in 2 weeks time.

    Hi all, just have a lil problem, I just changed my brakes and did everything by the book!

    But on turning the key (not starting it up) the ABS lights came on, both of them. I would start the car but the battery is almost dead!

    I did not! damage the ABS cable thing at all, but now the message will not go away!

    Will disconnecting the battery and re-connecting it help?

    Or just buy a new ABS sensor cable?

    Any ideas?

    Charge the battery, start the car. If the warning lights don't go out when the car is running, then get it scanned for faults instead of spending money on new parts which may not be faulty. If you disconnect the battery from the car while you charge it, it might reset your airbag light too.

    Does 'dash reset' not play a part here? That old 3 series I had done the same, dash reset cured it. Just a guess. In any case, you need a fully operational battery. A partially or faulty battery causes all sorts of issues.

    Hi peeps, I just went and got a new battery today and hey presto, all the warning lights went out except for a airbag light (I know what is causing that, removed seats with battery connected)
