My S320cdi (2006) has developed a glow plug issue.
The glow plug light has started to come on after engine start. On the first cold start of the day all normal.
On all 4 subsequent occasions today the light has initially gone out but come back on shortly after engine start but only stayed on about 10 seconds. After that has not come back on for the duration of each journey.
On all occasions the engine was not stone cold but at about 40-50 degrees so happening during the warm up phase only.
My Mercedes used warranty runs out in 2 weeks - if it is a glow plug I am not covered but if the relay is faulty I am insured.
What is the likely cause?
