My Vito 639 109cdi has recently developed a new issue.
When starting from cold, the Glowplug warning light illuminates for a few seconds as usual.
However a few seconds after I have started the engine the Glowplug light now re-illuminates for about 30 seconds.
The van starts & runs fine, so it's not urgent.
However I like to keep everything right, and hate not knowing/understanding things. A general search has failed to throw up the definitive cause for this, although the question has been asked previously.
So I'm hoping one of our resident experts may be able to explain this correctly for me, please.??
P.S. I have today replaced my glowplugs with 4x new Bosch GL008. This has not affected the symptom whatsoever.
