Do you know that HPFP failure can be one of the reasons why your BMW is not running as smooth and powerful as you want it to be? BMWs are famous for their accurate engineering and high level of performance, anyway, like any other car, it has components that wear down due to use and other factors. One of these important components is the high-pressure fuel pump or simply referred to as the HPFP.
When it does fail, it is capable of causing numerous issues that interfere with your driving experience. Below is a clear idea of what the high-pressure fuel pump does, why it fails, and how you can fix the problem so you and your BMW can continue to enjoy a smooth drive.
What is the Function of the High Pressure Fuel Pump?
The HP fuel pump is one of the most important components of your BMW’s direct fuel injection system. Its main function is to draw fuel from the low-pressure fuel pump and then supply fuel to the engine fuel injectors at a higher pressure.
This high-pressure delivery results in better fuel atomization, better combustion, and overall efficiency. When your HPFP is not functioning, your engine cannot deliver the precise fuel it requires at the right pressure and this can make your BMW begin to perform poorly.
Possible Reasons for HPFP Failure
- Wear and Tear: As with any mechanical part, the HPFP is designed to wear out with time and usage. The high mileage and extended use will put a lot of pressure on the internal structures of the pump and will lead to failure.
- Fuel Contamination: Fuel that is either dirty or of low quality may make its way into the pump and cause blockages or increased corrosion. To avoid this risk it is always advisable to use high-quality gasoline.
- Heat Stress: BMW engines have a tendency to run hot and the fuel pump is known to suffer from high temperatures. High temperatures can damage the seal and internal components of the pump after being subjected to long hours of heat.
- Manufacturing Defects: Most cars have been found to have faulty HPFP. Some car manufacturers, including BMW, have gone further and recalled specific car models and offered a warranty for the same problem.
How To Solve HPFP Problems
- Inspect the Fuel System: Whenever you suspect that your BMW has a faulty fuel pump call a mechanic to check the whole fuel system for signs of contamination or damage. This will not only fix the immediate problem but can help to avoid problems that may develop later on.
- Replace the Pump: After the diagnosis, the proper solution is to replace the damaged HPFP. Use products that are genuine or recommended by the manufacturer or the best aftermarket accessories that guarantee reliability and performance.
Ways You Can Prevent High Pressure Fuel Pump Failure Failure
- Use Premium Fuel: BMWs are built to be used with premium gasoline. Premium fuel is good for the car’s fuel system because lower-quality fuel can corrode the fuel system over time.
- Service Regularly: Always have check-ups and repairs with qualified mechanics who understand BMW cars. This is helpful when it comes to detecting possible problems before they grow into large ones.
- Avoid Prolonged Heat Exposure: High heat is not good for the HPFP and this will cause it to wear out faster; check on your cooling system to keep the engine temperatures down.
