Audi Q7, P0088 Fuel rail/system pressure too high

Any reason why the fuel pressure cannot be regulated fast enough to specified fuel pressure?

  • High press fuel pump faulty?

Q7 sent to us from another workshop.
Aftermarket airmass meter replaced by another workshop.
We replaced the SCV fuel press regulator solenoid valve with a genuine Bosch regulator with the same part number.
Any reason why the fuel pressure cannot be regulated fast enough to specified fuel pressure?
