Question about 1999 Mercedes-Benz C-Class

1 Answer

Bosch edc 5.3 fitted to MAN D2876 lf02 engine .Truck starts normal and idle ok for a while, then starts to push out white smoke frm the exhaust and runs uneven, and within seconds starts to run evenly again.Remove the plug on top of vertical slider on injector pump and found that if i hold the slider fixed with a tool the engine keeps on running evenly and doesnt start to misfire or smokes.The edc light does come on,on the centre panel(when the smoking starts) but goes away as soon as the engine runs evenly again .All circuits and components test fine -no shorts/dis wires . Sorry cant find the right selection in the product category.

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.

Check for oil in the coolent and coolent in the oil, both of these are usually caused by head gasket failare but not always. If these seem ok change the fuel filters, remember there are 3 on these trucks, check the air filter isnt blocked if your not sure leave it out as there expensive and you dont want to throw money away if its not needed yet. Once your sure you have fixed the truck re-fit or replace the air filter. Check the fuel tank for contaminated fuel and if possable check fuel pick up in tank isnt blocked, also try with fuel tank cap removed as the breather may be blocked.

I have a diesel engine that expells white smoke for 5 to 10 miniuts after start up? The exhaust also smells rich with fuel? I bought the truck used and am trying to fix the problems! Please help.


When an engine expels black smoke it means that the piston rings are going and is consuming oil. And when the color of smoke is white the engine is consuming more fuel. Both are harmful. Black to the engine and pocket while white to the pocket. It seems that the injector need careful attention.
Cold engine does expel white smoke initially. When the temperature rises to normal working temperature the smoke stops. This is normal in your case. 5 to 10 minutes to warm up is normal for any diesel engine. But any thing more than that needs attention.

White smoke coming out of the exhaust when starting the engine?


Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case   White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And  this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.
Thanks. you can rate this solution and show your appreciation.

Engine misfire


White smoke usually indicated it's burning antifreeze. Check your antifreeze level and oil condition before anything.

Hi Whitneyford
Your priblem sounds more like the glow plug timer relay than the exhaust. White smoke after start up is a sign of diesel entering the exhaust before it has burned completly. This is as a result of the glow plugs switching off too early, which is usually caused by one or more faulty glow plugs or a faulty timer.With engine COLD, IGNITION ON... Check voltage with all 4 plugs connected. You should have a reading of 10--12 volts
If there is no power, check in-line fuse on loom coming to plugs.
If power is present, check for How Long. If only for a few seconds, the problem is with the timer. This unit (the larger of the relays and usually black in colour) is fitted on the fuse board, and there are a few different types. They come in 7 pin..8 pin..and even 9 pin units.
The glow plug light is often NOT accurate (even with a new timer unit fitted) as to the time of heating, and you will almost certainly find that power will flow to the plugs for quiet some time after the light goes out. This is not unusuall with The Jetta Tdi.
Good luck.
I hope this helps you sort out this problem

If your engine is not misfiring but it vibrates too much while idling your motor mounts might be getting worn out. I had a Nissan with bad motor mounts. I was ok in park but when you put it in gear it vibrated a lot. It smoothed right out as soon as you started moving.
