Disconnecting glow plugs on 1.9 multijet
I'm trying to check the resistance of the glow plugs after the dreaded 30-second flashing on cold mornings, but stuck at how to disconnect the wire? I must be a total thickie as I can't find out anything on the subject. Is it just a case of pulling hard, away from the plug? I don't want to break the connector but I've tried pulling, pushing, turning, and cannot get the darn thing off.
For each of the four glow plugs, the feed wire goes into a plastic surround, about 3 inches long. This narrows down to the other endwhen it grips the top of the glow plug. The whole plastic surround will turn, but it's not unscrewing. Do I have to get that plastic off first to expose the connector?
Any help appreciated!
