air filter change should be told to ecu - reset adaptations...

yeah, any diagnose is 10x harder when remapped and modified... can't rely on ANY reading you get... only programmer knows what has been tampered.

If this is twin turbo, it has a wastegate... yeah, runaway sounds like engine burned oil after shutdown

same error code? It points to fuel quantity valve, next to hp pump, even it looks its not xentry code description... which leads to possibility it can be anything that cause low rail pressure, its just triggers that code (not a bad guess, it s quite common fault).

If its not rusty, it been fixed :) Search OM613 engine... not bad lump

There are special tool sets for snapped bolt removal. Injector bolt hole is just very deep so not all tools can reach the bottom (if needed). Yep, you need very small torque wrench for those (larger wrench range is not even starting from so low values, or at least it is very inaccurate).

I a presure sensor is showing anything else than 1ATM when engine NOT running, is that sensor is duff. Are reading changing rationally? Also DPF values? Just thinking if DPF has been removed...

All parameter except pressure are 'calculational', so ecu thinks it know ash content. How car starts regen; 1. calculated value reach limit, or 2. pressure sensor reading triggers level. So it is calculation value (you said pressure difference is not rising)? Some mechanical fault would make...

umm... it is not remapped, or adblue removed? New DPF told to ecu (reset made)?

Usually it is nozzle holder crack, leaking on foot of the injector and splashing around because cylinder pressure is leaking too. I can't remember cracked pipe happened either.

Oh yes, W163 was never fitted with 6cyl diesel... my bad. I assume fuel quantity valve was replaced with hp pump? How the problems started? What codes are triggered, if any?

Injectors leaking,,, Is this W163 or W164? Different fuel system... What pressure reading you having on crank?

Which car? If it is not museum age, probably yes, especially if you don't want any teentune lowrider...

This has been discussed before I think... steering column gear selector version does not have lock (AFAIK, it is not buzzing, and thus lack of that failing small electric motor), and its somehow walked around legal requirement...

I remember reading two cases where injector nozzle has been worn heavily, and coming loose. Then exhaust pressure is getting a route to the fuel side and causing tank pressurized. I still can't figure out how exhaust gasses CAN go to LOW pressure fuel side, perhaps cut section pictures I have...
