Bought it when my original High Pressure Fuel Pump started to works wrong. Low pressure for fuel. After replacing the car runs great like before. Satisfied with this.

I've changed the HPFP of my 535i 04/2010 F10, after my car developed the "long crank start" issue about 6 months ago. After the change, the car feels like new again :)

I tried to install this but it was slightly beyond my ability so I got a local shop to do it for me for $200. My 2011 335i (N55 engine) car was struggling more and more to start over the last year, and one morning threw a high pressure too low code and went into low power mode. Since installing this new pump its been starting well.
