Hi guys,
this is my first post here.
I bought a W124 E300D OM606 1994 about a year ago with 300k kilometers on it or 186k miles. Generaly good condition with lots of equipment.

The problem is low power,very high fuel consumption 20 mpg! , couple of misfires during the first start of the day and white smoke during acceleration.
Work i did:
-replaced glowplugs (2 were blown) and glowplug wiring a month ago
-cleaned air intake
-replaced air filter
-replaced fuel filter
-did a diesel purge (1l of liqui molly diesel purge directly on the fuel intake undiluted)

What i think it could be:
-injector blow–by seat leaking
-clogged catalyst converter
-bad injector
-injection timing

I didn't see any leaks or bubbles in the fuel lines.


I have been experiencing these problems for a while now and i finally found the time to resolve them because i really am in love with this car . :bannana:
I would greatly appreciate advice from gentlemen on this great foum.

Injectors

Yep, them. No no, don't cry! Not necessarily a need for new ones, possibly just need the current ones re-calibrating. But do prepare yourself. Then of course think of the joy of power, 40mpg, clean exhaust....!
