W204 c220 P0087 fault (fuel rail/system pressure too low)

[Haydo]

Moro! having a problem with mersu w204 c220 om651 motor, i get fault code p0087 when i accelerate hard but this only happens when i have more than 5 litres of diesel in the tank , once reserve fuel light turns on the car drives normal, anyone knows where i can start searching ? i have replaced one injector and is was faulty, also fuel filter replace together with the fuel pressure sensor (one in front of the fuel rail). Any idea where my problem could be ?

Are you using mb star diagnostic? If yes then follow the instructions what to check.
If no then find someone with star / xentry and follow the check procedures.

And please put the description to the fault code, nobody remember what each number is and I for one don't have enough time / interest to google every code.
