The abs light was on when I bought my car and on inspection I found that the wire had been broken off at the sensor. Probably when the coilovers were being fitted. But anyway, I have replaced the sensor but the light is still on. Im guessing it needs resetting as it hasnt gone off after a drive up the road either. Can this be done without diagnostics equipment? I only have a code reader for the modern rectangular shape obd plugs and not the large round plug under bonnet on the bmw. Would disconnecting the battery for a while do it?

If the ABS light is still on after replacing a wheel sensor then something else is awry...

Agreed, the ABS module may be on it's way out... there is a company that refurbishes them MUCH cheaper than it costs to replace them.

Damn.. frown I think I may end up just taking it somewhere and let them do the whole job. Such a pain when you need specialist diagnostics to reset lights.

You don't need a diag to reset the lights. You could do with one to find out exactly what is up with it.

Pump failure is rare (that's not to say it's not the case here) but it is certainly worth checking to see if the replacement sensor (or alternative for that matter) is also at fault.

In my experience, it's been the sensor every time.
