hi all, i have a 311 04 sprinter, when turning the ignition key,before actually starting engine you normally get 2 clicks (relay clicks ?) if this happens the abs,edc.traction and brake lights go off and all is ok, mostly now however i only get 1 click and these lights stay on constantly, this has been a intermittant fault for over a year, in the summer this seemed to have dissapeard but now its back,it seems to be this second click i think the first one is the glow plug relay?i have had it put on bosh diagnostics and it something about abs relay?where the hell is it?? tried a new brake switch
please help before i go insane!!
