Mercedes c220 cdi
I have a mercedes model c220 cdi, when the ignition is switched on the glow plug indicator light comes on for little
period of time then goes off ready for cranking the engine. When the engine starts, the glow plug indicator light should go off. Due to a fault the glow plug light comes back on again and stays on for approximately one minute and then goes off. This fault occurs everytime you start the car in cold or normal temperature conditions.
Please can anyone help?
