hello,hope i can get some help here...my sprinter(01 311cdi)kills the battery within 5mins of turning it off,runs/drives ok when running and has no problems starting at all,but i cannot find whats causing the battery to go flat(def not the battery as i have changed it)does anyone have any ideas?
Try disconnecting heater plug timer/relay common fault
feeds glow plugs all the time & flattens battery, ok unless you leave it for an hour or so then it will be flat
