Fuel rail pressure at ignition on engine off

[chimpusmaximus]

Hi

Had a few slow starts recently and the odd fuel pressure warning logged. Trying to find out what the ignition on engine off fuel preaaure should be?

Diagnostic shows commanded 200bar (found a post which mentioned this value on start stop) but my sensor is reporting 3bar.

Thanks

After key off it drops to 0.

Start up fault

Really happy with the help so far - have never received any remotely useful input from the dealership. But in there defence they never observed it faulting first hand only my videos. VCDS has been fantastic so far - only my inexperience limiting it. Reading the comments on the time stamps does...
