The first thing you need to check is the fuel pressure for the high pressure side.
Possible faults are the fuel rail pressure sensor or the fuel pressure relief valve.

Can you remove the bad service rating then?
Sorry, that not for you.
My screen switched customers and I never noticed.

The rail pressure sensor is on the fuel rail for the injectors and relief valve is on the pump.
