- Sprinter 312 D
Hello and thanks to you all for a very informative forum. Have searched and found some help but could do with some specific questions answering.
I have a sprinter 312 D
Glow plug light is coming back on indicating a fault.
4 out of 5 plug leads have 12V come on for 30 seconds. The 5th plug (nearest the driver) shows no volts and also I can't change it, no room to move the socket. Have changed the other 4 plugs.
The 5 plug wires seem to dissapear into the loom.
Q1: where is the control relay for the plugs.
Q2: is the time that the plugs are on for automatically adjusted according to engine temperature?, 30 seconds seems a bit long to me.
Q3: is the glow lamp controlled by the same relays that control the plugs.
Q4: are there 5 seperate relays, 1 for each plug?
Q5: am I going to have to remove the metal box held on with a torx screw (not sure what it is) to gain access to the 5th heater pug, or should I go to a garage where they may have a special tool.
If I get these answered then I'm well on the way to fixing. Thanks for any help.
