Hi there guys
I am beating me head against a wall here. Have been to the so called "merc specialists", local guys and spoken to all between including scrolling all the forums on the Internet and still don't have a solution.
Engine runs great 95% of the time. When its in its regeneration of the DPF state however it can pump out white smoke from over fueling (only when regening tho! So surely not injectors?)
Its not loosing any coolant
Diesel is getting into the oil and the level is rising at a rate of aprox 1l every 3000 miles altho this amount seems to vary, I then replace the oil so as not to damage the bottom end bearing.
I have done a compression test which is coming back as 24, 24, 22, 23 which i'm told is very good? Can someone confirm this?
It can stay in regen phase for sometimes up to 50 odd miles and over an hour of driving before seeming to give up and reverting back to driving perfect again for the next 300 miles. If these 50 miles are made up of shorted trips it will go straight back into regen on startup even when the engines cold...i thought it only did a regen when the engine was hot!?
There are no engine code, EML or anything... I got so fed up with "specialists" charging silly money for a scan and telling me its fine and must be injectors that i bought an Icarsoft v3 and it picked up an "over voltage", "under voltage" and "signal implausible" of the DPF pressure differential sensor. I have replaced this with a good boshe unit and no fault code since but I still have the same problems.
Am I correct in think injectors cant be the problem as if they were leaking I would have the white smoke at tick over all the time, not just when in regen.
A weird thing I noticed the other day. Looking at the live data mid reg the soot content was sat at -0.58g/l, yet despite these negative figures it still goes into reg again on start up....
Thanks in advance
