Hello Folks,

 

Looking for some help with my Octavia Scout. Its a 2010 and has completely died. The electrics still work but the engine management light is on the dash and the car wont turn over. I have an OBDeleven and it has produced 4 fault codes, one for each glow plug - P067100. I have checked the resistance across each plug and get about 0.8 ohms. I then pulled the coolant temp sensor and checked the supply voltage to each plug with the ignition on. I get between 5 - 6 volts supply voltage at each plug. At first I though this was odd because the Haynes says there should be battery voltage at the plug. Battery is sitting at 12.1 volts. But then I read that there are some VW plugs that have 7 volts supply so now I'm not too sure. 

 

Could anyone shed some knowledge on this issue or suggest any more checks that I can do? I was thinking of replacing the glow plug relay under the fuse box in the engine bay but thats just a stab in the dark at the moment.

 

Cheers

Good start, just noticed I put it in the wrong forum. Hopefully a mod can move it to the Octavia MKII forum for me

That looks more like an immobiliser issue than glowplugs, particularly if you get a "Beep" sound from somewhere in the depths of the fascia or engine bay rather than a whirr when you key the starter.

Zero attempt to turn over can point to a broken wire going (not going) to the starter motor solenoid.  This is the thinnest wire going to the starter motor. If wire appears to be intact - even with a gentle pull - unplug it and inspect for corrosion of the connection.

thanks for the tips guys, I'll check the starter motor wiring. I did initially think immobiliser issue before I read any codes but not sure how to test for this. I'll open this thread up in the Octavia forum because it may be more relevant there. Hopefully a moderator can close this one for me. Thanks again
