Any techs here then advice would be welcome.
Mrs 2013 C250cdi OM651 has twice had a EML and code throw up within the past month.
Just before EML each time car juddered/misfired and lost power similar to a fuel/air supply issue. Both are one’s have happened on or very near a regen with the DPF 96% full and 5G soot level. (Could be coincidence)
Anyway codes from Icarsoft MBV3 are:
P062B64 There is an internal control unit fault in the monitoring function for the fuel injectors. There is an implausible signal.
P1CDE00 The eco/start stop function detected excessively low engine speed during the start procedure. (This is after it stalled today)
Last time the car ran fine for a month after the code was reset.
So I’m leaning towards a fuel injection issue that’s initiated when a DID regen is asking for more fuel than the rail can supply.
Not sure if it’s injector related or boost leak related.
Happy to hear anyone’s thoughts especially on the P062B64 fault.
Car is on 109k miles with full service history.
Update to this. Took the car for another long run post already long work commute. Had diagnostics on the whole time. It started a regen on its own at 100% fill and ran like dog shit the entire time, lots of hesitation and now power. Second the regen had finished with fill level at zero it behaved perfectly throughout 30 miles of hard driving mix of driving hard, under load up hills. No issues. Fill level picked up quickly on DPF though and was 20% after just 15 miles. Leaning towards boost leak or a very rich mixture.
No smoke at all and decent mpg over 50mpg.
