Good evening,
I own a Merc with the 3.2 liter 6-in-line engine coded OM613 from the late 2001's era. It has about 150.000 miles on the counter which is nothing to what this engine can do. I saw them in Germany for sale with over 560.000 miles behind them, still going for 2000 good old Euro's.
Problem:
Things I already did to this engine:
I don't have any issues concerning power output, it doesn't go into limp mode and the kick-down works like a charm. No limitations in the rev's band, it goes up to 5500 rpm without any problem.
I did read the 400 messages (or so) concerning this subject on this forum already and no, I don't agree to the remarks a diesel may produce black smoke and I have to live with that.
I also read in a very wise comment in my opinion that cleaning out the EGR valve is not going to solve the problem it's giving on this specific type of engine.
So, bear with me just one more minute here:
Am I right to assume cleaning out the EGR doesn't always solve the problem?
Second, there is still a chance the injectors are out of specs because I don't have the proper tools to check it?
Am I right the EGR is the fist part to replace after all I did to the engine? Oh forgot to mention it doesn't burn any oil, the level is the same after 3000 miles although I changed it a few times.
Please let me know, A bit of a black haze on acceleration I can live with but this is a full size black smoke screen. Until the turbo kicks in, then it's gone.
About the EGR, I did put the electronic bypass in it and when I disconnected the EGR electrically it didn't throw any fault codes or went into limp mode, thus saying the EGR-delete which is stated on this forum worked, it just didn't solve my problem. Is it fair to draw the conclusion the EGR is stuck open?
Just let me know your thoughts about this issue, I just want to get rid of the smoke-signs which attracts Indians thinking there is a party going on out here. Anybody out there has an Indian-smoke-sign-blanket for sale?
In the meantime, thanks for reading this. If ever you got any suggestions to my statements and/or problem I would be very pleased to read them in this topic. Thank you so much in advance!

PS: It passed it's MOT like this.....

Problem:
- Black smoke under acceleration.
- Hesitation to accelerate from low revs. Once the turbo kicks in it's gone.
Things I already did to this engine:
- Took the intake manifold out and gave it a thorough clean out. Swirl flaps are free and the actuator is working fine.
- Checked all hoses from the turbo to the intake manifold, they are fine. I did clean them out.
- Changed the MAF which didn't make any difference.
- Put a new thermostat in it. Needed but not necessarily related to the problem.
- Rebuild the turbo because it was leaking oil, eventually I bought a new one. The rebuilt one didn't have a problem after all.
- Cleaned out all injectors, I can only check whether the spray pattern is ok because I don't have a test bench.
- Cleaned out the EGR valve, it was really soothed up.
- Changed the fuel filter, had to be done but didn't change anything but starting up more spontaneously.
- Changed the air filter, actually that was the first thing I did.
- I did put in the electronic EGR bypass which is described on this forum to no avail.
- Used injector cleaner over the last 3000 miles on every fill up.
- Did the "Italian tuneup" like 40 times.
- Changed the camshaft sensor.
- Got me a diagnostic tool which didn't show any faults.
- Changed the engine oil and filter, 3 times already.
- Cut off the first half inch of all vacuum hoses to be sure they are tight and not loosing any vacuum.
- I replaced the oil separator membrane.
- whatever could have been done I did but it's still pouring out a BIG cloud of black smoke under load/kick down.
I don't have any issues concerning power output, it doesn't go into limp mode and the kick-down works like a charm. No limitations in the rev's band, it goes up to 5500 rpm without any problem.
