What does it mean when the glow plug light goes off when ignition is switched on, but comes back on when the engine is started?
When mine first did this last week, it would sometimes go out after restarting, but now stays on all the time.
I have looked at the relay, expecting to find an 80A fuse, but there does not appear to be one.
I will get a multimeter and test the glow plugs, but always thought that with faulty glow plugs, the light goes out after a few minutes.
Also, it looks as if I need to remove some fuel lines to get at the glow plugs for cylinders 1 and 4. Is this true? Or is it possible to get them out without removing the lines. I would prefer not to disturb them if possible, otherwise they may not seal properly afterwards. The car is a 2002 c220cdi estate.
