The very instant it loses power it would be interesting to see if you switched it off and start it back up, it starts ok. If it was very reluctant to start I wondered whether it jacking lifters up and decompressing the engine under power, this wouldnt trigger any fault codes.
There has been some issues in the states and some have found using a very good oil flush and regular oil changes helps. If it was a lifter problem it must have the correct grade of oil used to reduce any chance of this problem
On the diagnostics side has anyone actually gone into EOBD faults pending & freeze frame ? This is not to be confused with a dealer going into the main ECU into diagnostics.
EOBD is forever overlooked & rarely used but you need to remember when a fault occurs it has to occur 3 times in sucession to flag a fault.unless its permenant , faults pending will list a problem that occurs before its recorded ! only emmission related issues before anyone gets too excited.
Freeze frame captures the information at the time of a fault !
I have carried out diagnostics on so many cars that have been in and out of a dealer and the basics been missed
Is yours fitted with a DPF ?
