1997 E290 Glow Plug
1997 E290 Glow Plug
Just bought myself a 1997 E290 (2.9L OM602.982), which I love so far. However I'm relatively certain that I have 0 out of 5 glow plugs working, based on how hard it is to start.
My only issue is that I'm in North America, and the E290 was never imported here, so no one has a listing for what glowplug it uses.
So my question is, does anyone know the Bosch part number for the glowplug these use?

The PO mentioned that he thought the hard starting was a result of an air leak in the fuel system. He thought he had seen bubbles in the clear lines leading to the filter assembly. I can also smell diesel while driving it, so I know I have a leak somewhere. It looked to me like the return lines are weeping (this will be fixed tomorrow). Could a leak cause the fuel system to loose its prime after a couple hours to the point of hard starting? I'd also like to replace the O-Rings that the seal the fuel lines but have been unable to ascertain what size they are. Are they a standard metric size that would come in an O-Ring kit or are they a dealer only item?
-thanks for the help so far
That's actually a very valid point. The car was sitting in the 30*C sun all day and the temp gauge bumped up off the 40* line when I turned the key on. So the engine was pretty warm all things considered. It still took about 5-6 cycles of the starter to get it to catch. As such I'm going to agree, the glow plugs probably aren't the issue here.

I don't know about the O ring sizes. They are a common problem on W202 and W210 chassis turbodiesels.
Does that OM602 have the same style quick coupling hoses as the OM605 and 606 engines ? If they are then it is very likely that the O rings are your problem. Hell some people had to replace all the hoses until the car would start.
It is possible that you lose prime in the system due to an air leak.

A quick test you could try in the meantime is to disconnect the fuel supply line from the tank and connect it to a fuel can above the engine level. When you shut off the engine air won't get into the lines since the fuel is slightly pressurised by gravity. If it starts fine then you have isolated your problem.
The other hard line running from the fuel filter to what I believe is the fuel heater was also wet. So I'd say air leaks a plenty is the issue here...
I found the leak last night after I got home. Turned off the car and waited a few minutes. I could see air bubbles rising up though the hard line running from the IP to the fuel filter. It looked like it was leaking from the connection at the pump. I believe there is a copper crush under that connection which I also ordered with the O-rings from the dealer.
