my work place owns a 2005 mercedes 316 cdi van, it has this problem with starting sometimes when cold. when the key is turned to start poisson all the dummy lights come on like they should but the a/c fan turns on. and if the fan turns on the van will not start. If the fan comes on, the glow plug light remains on. If I put an electric heater in the cab for some time (depending on ambient temperature) I will turn the key on, after a few seconds the glow plug light goes out and the sprinter starts normally; but after the van sits after a night it will do the same thing. does this make sense to any one. is there some type of sensor for the glow plugs or a/c fan sending the wrong temp to the glow or a/c to cool or ???? When it acts up, I get a P1482, P1610 and P2134 codes.(2 glow plug, 1 engine control relay) I put in a known good engine control relay with no change. any ideas
