In some cases, a bad HPFP can even lead to engine damage. If you’re experiencing any of these symptoms, it’s important to have your HPFP checked as soon as possible.

The N54 engine is a reliable and powerful engine, but it is known to have some issues with the high-pressure fuel pump (HPFP).

How to Choose the Right HPFP
When choosing a HPFP for your BMW 335i, there are a few factors that you need to consider.
- Price: The price of the HPFP is an important factor to consider. OEM HPFPs are typically more expensive than aftermarket HPFPs, but they are also higher quality.
- Availability: The availability of the HPFP is another important factor to consider. OEM HPFPs are often difficult to find, while aftermarket HPFPs are typically more readily available.

To replace the HPFP, you will need the following tools:
- A socket set
- A wrench
- A 10mm hex wrench

- A fuel pressure gauge
Step 1: Park the car on a level surface and turn off the engine.
Step 2: Remove the negative battery cable.
Step 3: Locate the HPFP under the intake manifold.
Step 4: Disconnect the electrical connector from the HPFP.
Step 5: Remove the two 10mm bolts that secure the HPFP to the intake manifold.

Step 7: Install the new HPFP in the reverse order of removal.
Step 8: Reconnect the electrical connector to the HPFP.
Step 9: Connect the negative battery cable.
