idle problem
idle problem
I own a W210 300TD 177hp with OM606.962 engine.
It has a problem....
When i rev it goes just fine, but when the engines comes from higher to lower rpms, near idle it stars shacking for 2/3 seconds and than stays fine till next rev!!!
does anyone knows what is happening here?
Thanks

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

There's even a 'Kit' of 'O' rings available on fleagay for these....
VERY common for these to leak in air when running....

the o´rings were all changed, even the pre fuel filter....
But i do not understand what is the "stop-solenoid on side of injection-pump"....
Do you have a photo of it?
Thanks for all
ok i already know what it is....i googled it...
What should it do?
The car is from 1997 but it has only 133000kms...
Fuel filter has 900kms..

open the injector line one after the other and see where the idle does not change much. This cylinder might have an issue.
Next change the injector from this cylinder to another cylinder and see if the issue follows the injector or stays with the cylinder.
Report back.

the injectors are fine....
The EGR is working properly...
I do not know what to do..
thanks

well for comrade Martins i´m having the same problem in a 605. exact the same problem. sometimes when rev down from high RPM it seems like the idle governor is not able to keep the engine at idle, and rev´s to about 500/600 and then goes back to the regular 800/1000.
in the past i had an air leak in fuel system, and besides doing this, the engine stalled at 3k or around , or when effort was needed. lesson learned if u don't see bubbles in the IP supply line " is not air leak".
bet if u replace the pre filter that will stop.
for Tomnik , well my engine is running for 80k on several types of fuel mixed with Jet A or diesel of bad quality, the best i found till now is engine oil plus diesel or jet A at 50/50.
the other day replacing a glow plug i saw that a huge mess was on happening prechambers, so i don't think my case is correlated with martins.
Do anyone have an idea of what used engine oil can do to IP? injectors , well injection system?
About the lift pump, do they last for ever? what min pressure should be expected at IP inlet?
thanks

yes i have filter and use to filter this "fuel" before having it in the tank. something is going on in that engine is not powerfull as it was even when back to diesel 100%. maybe is something with the control chain, just can guess.
the prechambers well i´m not sure about whats inside, but there was very strange matter in the glow plug, more than it should.
BTW is possible to remove PC with the cylinder head in place? is a 605.
where can i find a repair shop manual for this engine?
thanks

you can check the PC visually when the injector is removed. Check if the "ball" is in place and (using a screw driver) fix.
I don't know the 605 engine well but the PC should come out by using a pull hammer (remove the glow plug before).
I have issues with filter even filtered before with only 5 % engine oil. The black stuff is sitting at the bottom like mud even when passing the 2 micron filter before.
What was/is the issue with the glow plug you mention?

The glow plug showed a lot of carbon plus white and yellow stuff around it, which is not common, i mean i should not be there a that quantity. diesel in Europe is free from sulfur.
well u might have the same problem i had with that black stuff, make a strait hole in the tank (eliminate tank pre filter) and get a 100 micron net and build a small filter that u can remove every now and then, the black stuff in the tank is there and u have to get it out to prevent clogging of the main fuel filter , get the fluid hot enough to burn. that´s all.
by the way u know anyone that has a repair book for that engine?
in your opinion is possible to control VNT through boost pressure and back pressure?

Example.
The ECU demands for example 1,500 volt return @ 9-11ccm of fuel,350rpm but what happens is that at 1,500 volt the pumpe gives 14-17ccm of fuel, then the ECU goes down to ex 1,400 volt that is out of range, ( tolerance is +-0,060volt) ecu corrects and the sving has started.
New 210 valves, washer & orings and the car work perfect again if it not have been tuned in the ECU or by box, then the fault can bee there.
This is the samt thing thats happens to VP37 when the governor is loosend and you change gasket and dont have the proper computer / testbench to adjust with.

07-02-2012, 11:16 AM #14This is a common fault on the EDC M-seriepumps, The deliveryvalves are worn out, they give to much fuel on low idle,

and engine repair manual for 605 engines? do u know where i can find it?

difficult to understand what u are talking about, we are common people. in my case my pump is mechanical, i don't know the case of "Bmartins" well it could well be the delivery valves or some sort of leak somewhere the thing is send a IP for overhaul is not cheap, actually i more than my 124 worth's all together.

I think dieselmeken is pretty sure in his opinion....
I took a bosch Car Service especialized on Fuel pumps and a old guy told me that the problem was in the electronic part of the pump, which stays in the end..
The car cannot hold the exagerated fuel that the pump delivers...
The problem is common in this type of pumps...said the man.
My car only has 132000kms..
For Dieselmeken.....
in your opinion what should i do to correct that?
For Barrote..
My pump is electricall.

Yes i know about that, change it for one mechanical and u will end up having a all less problems in the future. the electrical part of the pump is only the governor which is ruled by and electronic algorithm. So called ECU , which needs for working properly: pedal position indicator, air mass flow indicator, air mass pressure indicator, engine rpm indicator, and a few more electronic elements, which when damaged , the engine simply will not run well
as usually happens with my OM612, which one of this days i will throw fire on it. Despite the question was not for me, consider change the IP to one mechanical.
Can tell u that a fellow from Bosch service center asked me for overhaul on one of those 1000€ so.

If you dont have any problems with the EDC governor, I remember there was a service letter that said that the cable from EDC to ECU was to change in some ways.
Or is the car tuned with a box? remapped ECU?
I should take the pump out and let a dieseltech run it in a bench, or just try to swap the valves on place.

08-13-2012, 06:36 AM #23Yes, and I have the same suggestion as in my first answer, deliveryvalves.

Can you get me those Service letter!!
Swap which valves?
