Based on the age of your automobile, the current average price of a fuel pump change for all models is somewhere between $611 and $894 (with materials and labor).

However, some places can go as low as $220 and as high as $1,062 for the parts only. Labor expenses, in these cases, are expected to be between $124 and $260, with component costs ranging from $95 to $854.

Therefore, according to where you decide to fix your bmw high pressure fuel pump, it might cost more (or less) than that. A BMW 335i fuel pump replacement, for example, costs between $1.273 and $1.468 on average. The cost of labor is projected to be somewhere around $188 and $237, with parts costing around $1.085 and $1.231.

Is it possible to repair or change the fuel pump in my BMW by myself?

Technically, yes. However, even if you already have the skills and supplies to repair it, it may only be a temporary solution. You’ll almost certainly need to replace it shortly. The correct course of action is to drive your car to a BMW-specific repair location and have them analyze the problem. It’s possible that it’s not your gas pump after all.

Replacement of a Fuel Pump: How does it work?

A fuel pump is a small electrical motor installed within your fuel tank. It ensures that compressed fuel goes towards the motor to propel the vehicle. The fuel goes through a filtration system along the route.

It can be installed either within or outside the gasoline tank, inside the fuel flow line. The majority of gasoline pumps will survive the life of the vehicle, although they will fail eventually. An automobile that won’t start or stops after it has started is an indication of such malfunction. Alternatively, the fuel supply might get starved over time, leading the warning light to show up.

If you hear a whirring noise coming from your gasoline tank, the fuel pump may be ready to fail. Fuel pumps don’t usually generate noise. A mechanic will need to reach the failed pump through an open structure inside the rear seat or by disconnecting the gasoline tank from the car.

What can cause an HPFP failure?

The malfunction of your BMW’s high-pressure fuel pump has no definitive reason. It might be the consequence of anything in the surroundings. For instance, extreme heat, causing the item to break down, but it could also just be bad manufacture. But first, let’s look into a couple of the possible reasons for your HPFP failure.

  • The usage of low-grade oil: The use of oil other than the manufacturer’s suggested oil in your vehicle might cause your high-pressure fuel pump to wear out and fail.
  • Oil changes are in short supply: The friction between the camshaft and the lobes is increased by low oil levels or a lack of adequate service intervals.
  • Leaks inside the injection pump: Because of the high pressure caused by pumping gasoline into the injector, there is a greater chance of a leak. Because of the carbon build-up, if the injector valve bursts, the engine’s functioning is affected.
