Help with rail pressure pre-start-up.

I planned on looking for them tomorrow. I hope I find some.

The problem with checking fuses it that the car does not go to sleep because you have the driver door open

Is that not why you lock the various latches by hand, particularly the driver door and the hood latch so they are closed as far as the car is concerned, but in reality they can be in any position you want them to be in except actually on the striker. Of course you have to make sure you have no issues(dtc) with your latches to begin with.

The latches, hood and driver door, were reset so as far as the car knows...the doors were closed.
A full scan was done to insure there's no issues with the door module. The vid in my post, #24, shows this.

Today's readings. Humidity is 89%

• Rail pressure: 7 bar
• MFD Outside temp: 70.6F
• MB004 - Coolant: 69.8F | IAT: 69.8F

I want to try something now...tonight, I am going to start the engine when it is cold but shut if off quickly. This should pressurize the rail but not create much heat. Then check the rail pressure and temps in MB 004 and 230 and again in the morning. I would expect the rail pressure would be higher in the morning than when it is shut off hot. The hpfp outlet valve, the FPRV, and the injectors should contain the pressure resulting in a higher residual pressure in the morning...ambient temp will show fluctuations in the morning pressure of course. If you feel like doing the same...much appreciated.
