Hi All, Been having problems with the abs light staying on on the digi dash on my MB UR quattro, I think now after doing the usual things I could have a dodgy relay, dose anyone know of a good Auto Electrician who could check them out to see if they are working, any advice would be gratefully appreciated, Cheers, Simon

Does the light come on when started then stay on after moving away to allow the system test? More likely to be the pickups... common problem.

Hi Guys, yes the light stays on all the time, I have changed the sensor caps, checked the fuse on the relay behind the glove compartment, checked all electrical connections and sprayed with wd 40, checked the ring gears on the hubs for the abs pickups,pulled the relays out on the abs pump and multi socket on both pump and the abs brain in the boot and sprayed with wd 40 just in case of a dry joint, tried turning the diff lock on and off, tried the abs switch, so the only thing I can now think of is the relays gone tits up or the pump is buggered, so I am hoping someone might know a good auto electrician in south west Devon. Regards, Simon
