Glow Light Indicator coming on whilst travelling

[kentsbankpo]

Hi

The Glow Light indicator occasionally comes on during normal running - then goes off after a minute or so - on my 190D 2.5

I can find no reference to this in manuals etc -

What could be the cause of this :?:

and more importantly, what is the solution :!:

Thanks in advance for advice

When you say the glow light indicator,
do you mean the preglowing indicator, on diesel engines...???

Maybe like 320cdi.

The light came on when the glowplugs needed replacing. Best to replace them all at the one time.
