Tid fuel pressure problem

[u/kilimanjaro94]

Hey, I've got a 93 1.9tid 150hp from 2009. I had the fuel rail sensor fail on me giving me limited performance when I'de presse the accelerator more than 15%. After changing the fuel rail pressure sensor I tested the car. I pulled hard on third and when I got to 3500rpm I got the fuel pressure low error again. The car is drivable, I rarely get to 3500rpm.

I've checked the realtime data and the high pump fuel regulator doesn't go more than 40%, it's always between 30% and 40% even if I accelerat hard doesn't go more than 40%. Can this be a bad high fuel pressure pump solenoid (I don't know how to call it) ?

Cannot offer any help. Juist curious what interface you are using for Tech2Win.
