Check the water seperator filter. It may be full.
you need to check your glow plug relay it is most likely going out you can jumper it to see if the glow plug light will come back on to start engine
Wait until the light turns off then start the car. Diesel engine?
The glow-plugs are located under the valve covers. There is a single wire that comes out of each injector harness that powers each glow-plug. Disconnect the single wire from the glow plug. Connect the gator clip of a test light to a positive and probe the glow plug terminal with the test light. If test light does not come on the glow plug is bad.
Yes. It is in the warning lights below the speedometer on the cluster. If the glow system isn't working the light will not come on.
I don't know what YOUR vehicle does specifically, but most diesels have "glow plugs" that come on when the engine is cold. The glow plugs warm a spot in the cylinder making the engine start much more easily, especially in cold weather. I can't speak for YOUR engine, but in general, there is usually a light on the instrument cluster that flashes while the glow plug is heating. Once the glow plugs are up to temperature, the light stops flashing and you can start the engine. If there is any doubt, read the section of the owners manual that describes the operation of the glow plugs.
A glow plug problem can be spotted by the vehicle having trouble starting the engine. The indicator light in the for a glow plug can indicate a bad disconnected or corroded glow plug, or even a bad temperature sensor. If when you first start the engine there is a misfiring until the engine warms up, it is a good chance a glow plug problem. Usually misfiring will cease after the engine has been running about ten minutes. One of the last systems of a bad glow plug is you see white exhaust when starting the engine. Diesel is let into the combustion chamber to start the engine. A bad or even disconnected glow plug will allow diesel to leak from the chamber into the exhaust. The fuel is then ignited in the exhaust pipe and produces a white smoke. Once the engine again warms up the white smoke will stop.
The glow plug relay is located right of the center of the fire wall, to see it and get at it you need to remove the light gray cover from the top of the engine.
Try checking all connections and the solenoid.
You can test each glow plug while still installed in the engine. Just get a test light and connect it to the positive terminal of the battery and touch the point of the test light to each glow plug terminal. If the light lights up the glow plug is good if not it is bad. You can replace the one or more that are bad or replace them all since they may not be too far behind.
yes it can
Why are you illiterate.
All Mercedes cars will only go to the "Start" position only once, to prevent the initiation of the starter while the engine is running. Check the glow plug light before you try to start the engine. The light has to go out before you start the car. If the light doesn't come on, then you may have a problem with your glow plug relay, or one of your glow plugs is dead.
