Primary fuel pressure low

Friend of mine got this error code on his 2019 G23 with H6 engine. Dealer really backed up and he’s already been down for 2 weeks. Anyone have a fix?

Check your fuel pressure at the rail to rule out the sensor. Look for kinked lines. If that all checks out it’s likely your fuel pressure regulator or one of the pumps.
