Glow Plug Dash Light - None?

[leicschris]

Hi All

On my 2001 S320cdi there is no glow plug light when I turn on the ignition.

On reading my user manual, am I right in understanding that if there is a fault with the glow plug system that the light will not show when the ignition is turned on.

I understand faults can also show with the light staying on after the engine is running but I have never heard failure to light also means a fault.

Will this be a glow plug relay fault or individual glow plug fault?

I know during my recent star printout that a fault was logged with 3 and 4 glow plug and intend to change all the glow plugs when I learn how to do this, and have the courage to tackle it in case they are stuck.

Don't remember seeing anything on the star report about a faulty relay

Thanks

Chris

Could be the bulb?

Hi

I did think about the bulb being broken and that is a possibility

The manual says under the driving section about starting the car "if the preglow lamp does not light up this means there is a fault in the pre glow system which must be rectified immediately by a mercedes Benz service station"

I wondered if anyone knew what fault this refers to, relay or glow plug
