Smoking something fierce...

I owned the exact same car (same year too). Assuming the air and fuel filters are new, you should:
Check your timing chain stretch, if the chain is stretched then properly calibrating the injection pump will be impossible.
Check/replace your injector nozzles.
Set the injection pump timing, and adjust the ALDA.

The mercedes mechanic (old **** german guy... No kidding) changed the injectors without asking me first.. after I had requested a written quote
(And then he tried to charge me $600)
I got mad and so did he so he just put the old ones back in and I drove away paying $0 but with some valuable info.
Injectors alone did not fix the problem.. he said it was like 50% better with the injectors.
I think the other 50% is the injector pump being just a little off time.. (maybe.. I hope anyway)
So what I'm going to do is properly set the time on the injector pump then change the injectors.
I HOPE that will fix it.
^ to answer one of the questions above about why a not working turbo would make it smoke...
The answer is the ECU is programed to dump the amount of fuel needed for the engine under BOOST... and when you're under boost you need more fuel soooo
No Boost = To much fuel through the rpm range where the turbo would usually kick in...
The engine does have a mechanical injection pump but it also has a MAF and the injection pump seems to also be controled by electronics...
maybe the solinoid on the injection pump is bad? (IDK enough about the engine to know if that's possible)

Sounds like the Merc diesel you have is a bit more modern than the ones I've worked on. They did not have electronics except to control the glow plugs.

^ Carburated cars do not have the problem with busted turbos because it's a mechanical system. The ECU in a fuel injected car has no way of knowing if the turbo is working or not.
Anyway... Anyone here know where I can get a FSM from??
I need to know how to properly set the injection pump timing..
The car is Nailing a lot under 1200 rpms after I got it back from the mechanic, I think it's because he put the old injectors back in a different order AND the injection pump timing is off.. it had a litttle bit of nailing before but now it's worse.
I think I have bad injectors and the timing is off, that's what makes the most sence to me ATM anyway..

Go talk to experts here. They have master mechanics that have published articles on diesels in prestigious auto journals, so go ask them for help.

Hi everyone. I have exactly the same car, same year, same problem, i tried many things too.. then i used the liqui-moly "DIESEL SMOKE STOP CONCENTRATE" and is 90% better now, i used it twice. Maybe you can try the same its a very cheap additive. Hope it helps you.
