Mercedes C220 Diesel EDC light

[stoddy2k01]

Hi i have a 96 Mreg Merc C220 diesel and in a morning when i go to start it the car starts ok then after about 15 seconds the edc light comes on then it cuts out.
I start it again and the engine seems to just rev up then cut out again. so i start it again then the engine runs as if nothing is wrong. it's just in a morning or on the cars first start up of the day and its. any ideas would be appreciated
Kind regards.
stoddy :roll:

Hi stoddy. I believe that you are in the grips of winter at the moment. Diesels are more difficult to start in winter and it is not unusual for a diesel motor to start race away and stall on first start up in winter until the cylinders warm up.

Sounds like an air leak at the filteer connections. After a couple of starts the air is drawn through the pump and expelled. Check the fuel feed pipes for air bubbles.

Thanks could it be the fuel line o-rings and if so how big of a job is this thank you.

Heater Plug light.

The heater glow plug light just stopped coming on the other day i started the car but i noticed that the light did not come on but when the car had started the light came on then for about 15 seconds then went of now the light does not show at all and the car is not starting straight away it takes a while. Any Ideas. thank you.

sounds as if new Glow Plugs are needed or at least test the circuit to make sure you have a live feed

Glow plugs.

Thank you.
I changed the glow plugs and they are working. but the glow plug light still comes on after a mile or so then goes off. i tested the plugs with the ignition and they do all work. my merc is a C220 Mreg 94 Diesel. would it be the relay or would it have to go to a garage and put onto the computer to be reset. ( I dont know )

Had the exact same problem with my 94 c220d. edc light. hard cold start and that. Change the 4 o-rings on the pipes that run to and from the diesel filter. (3 are the same and 1 bigger 1). check for air bubbles running through the clear pipe (pump supply).
