Glow plug error. What shall i check next?
ok, so ive had a lot of trouble trying to find out why my GT JTD keeps throwing up a glow plug error message.
I replaced my 18month old NGK glow plugs for a set of Bosch items last week. Checked the glow plug fuse and was ok.
Still got the error message. I checked the resistance using a multi-meter of all plugs and they came out fine. I also wired them up (out of the engine) to a live and earth, and the tips lit up very quickly.
Next i checked the voltage at the wiring of each plug. These showed a minimal 0.46v.
I also checked the voltage at the glowplug relay. Showed 12v going into it, but then only 0.46v coming out of the plug tips (G1, G2, G3, G4). So I assumed my relay was at fault.
New glow plug relay ordered and fitted this evening - still getting a glow plug error!!! Its driving me mad.
What should i check next that i havent already done so?
