Default Lexus is220d loss of fuel pressure plz help.

Hi. I have a delicate issue with my lexus. Started 2 month ago
Long story short. Start to experience loss of power while driving, one of the mechanics run real time data on it and it shows "loss of fuel pressure rapidly" those was his words.
Please if there is anyone who can help or had similar problem please share...


Also car door opens only on driver side using key, some time all car opens as it should. I'm not sure if this problem related or not.

Two totally different problems.

I have very little knowledge on your diesel platform; however, it sounds like you're having a fuel-delivery issue. I'd check your in-tank fuel pump(s) or a mechanical high-pressure pump in the engine bay.

Good luck!

Well...
I have changed fuel pump from fuel tank
Changed maf sensor, fuel rail with both sensors, sensor from hight pressure pump, cleaned dpf, cleaned egr valve. Went to 4 different guys for diagnostics.
Last night have tried disconnecting battery and connecting it back to reset ECU.
I feel like I'm doing everything in reverse in terms of finding the problem.
Today car feels good, will give it few days.
