It's within spec, and even at -0 under load it's still within spec!

The car should drive even with the fuse for the lpfp removed, so long as you do not accelerate hard, and is a good test of the pumps integrity.

I suspect your issue lies elsewhere such as the wiring to the HPFP and or its connectors.

Thanks for the feedback.

Indeed, I tried it with the engine running and the LPFP relay removed. Engine keeps running and pressure is dropping even below 0 !

Do you have any usual suspects for such faults (which connector to check, how to check it) ?
And ideally some pictures or a DIY ?
