How to Fix a Clogged Fuel Injector in Your BMW

One problem that can occur in your BMW is a clogged fuel injector. When your fuel injector gets blocked by dirt and debris buildup, it will reduce fuel flow and can prevent the fuel from combusting properly. This will often cause a number of nasty issues to manifest, changing the way your BMW’s engine performs.

Below are a few signs all car owners need to watch for to determine if their fuel injector is becoming clogged. Some of these include:

  • The engine seems to run roughly.
  • Engine cylinders are not firing well.
  • The engine begins to have trouble starting on the first attempt.
  • No-start condition of the engine.
  • The fuel consumption in the vehicle goes up and efficiency deteriorates.
  • Poor engine emissions.

If you notice any of these problems in your BMW, it is important to visit one of our expert mechanics as soon as possible.

Why does the fuel injector get clogged?

Fuel injectors can get clogged for a variety of reasons. Often it is from hydrocarbons, or sediments, that are able to get into the fuel. Most of the fuel that you will use has some ethanol inside of it. This is a hygroscopic material, which means that it works to draw moisture from the air over to the fuel. The water found in the fuel is able to rust some of the internal components.

It is not uncommon for this rust to make its way into the injectors when the fuel filter goes bad, which is why both of these parts need to get checked often. Sometimes smaller and older service stations will have debris and sediment in the storage tanks that can make it to the injectors before being pumped into the fuel tank. The injectors sometimes get gummed up with varnish when the fuel is left inside the tank for a longer period of time.

How to Unclog the Fuel Injectors

Although there are some different additives you can put into the fuel injector to help clean it out and unclog it, these are not very effective, especially if the clog is pretty large. The only way to truly remove the clog is to get inside the injector. In fact, these additives can often make the problem worse. They are good at cleaning anything they touch, meaning they may loosen the debris and then add this into the clog, making the clog bigger and making it harder for the fuel to get through.

Instead of trying to fix the problem on your own, it is better to visit one of our qualified mechanics to help. They can take a closer look inside the fuel injector to determine where the problem lies and what needs to be done. They will actually get inside of the injector to see where the clog is and physically remove it, cleaning out any other debris at the same time. This will keep the fuel injector nice and clean so it can work the way that you want.
