Please help. This is my first time owning a bmw nd she was running perfectly since I got her. It’s been about 1.5 years since purchase nd now she is having problem during acceleration I went to scan her today with MHD nd this is the outcome.

119404 - Rail pressure sensor, signal:
Permanently stuck.
11A002 - High pressure fuel, plausibility
Pressure too low.
- DME shadow (inactive) codes -
11A401 - Fuel high pressure during fuel injection release: Pressure too low.
11B401 - Fuel high pressure or after enabling injection (2nd ambient condition set after delay): Pressure too low.
11B501 - Fuel high pressure after enabling fuel injection: Pressure too low.

What is the cause of this nd what steps do I need to take to fix it?

High pressure fuel pump probably failed. It’s an easy item to replace if you like to wrench

Oh perfect. Yeah I don’t mind getting my hands dirty. How much does a HPFP usually cost for bmws?So otw home from work about .9 miles before getting home the drive train malfunction error came on. Could these codes be causing that error to pop up
