BMW X5 Fuel Injector Problems: Symptoms and Solutions in Oldwick

Among the several parts of the BMW’s engine, the fuel injector is an essential part that can deliver the proper amount of fuel to ensure efficient combustion. Thus, the fuel injectors are spraying fuel into the engine through the electronically controlled valves. Moreover, it has an atomizing nozzle that can distribute the diesel for optimum efficiency and combustion.

Thus, the BMW X5 has one fuel injector per cylinder. Through the following process the fuel injector function in your BMW:

1. First, the fuel pumps in the BMW are pushing petrol or diesel through the fuel lines to the injectors.
2. Next, the engine control unit is using the sensors to function at the right time for firing the injectors and spray the fuel into the combustion chamber.
3. When the ECU is activating the injector, the fuel is sprayed into the combustion chamber through the nozzles because they are very small and the fuel is atomized to burn efficiently.

But without regular maintenance, you will notice that the fuel injectors have problems or become clogged due to the debris. Here are the lists of symptoms that are associated with the failed fuel injector in your BMW.

Misfired engine

If you feel that the engine of your BMW X5 is misfiring frequently or having delayed after you press the accelerator pedal and then make sure that your car has a failed fuel injector as well as a block in the nozzle.

Thus, the failed fuel injector unable to deliver the fuel required by the ECU, so the fuel and air mixture in the combustion chamber doesn't perform well and causes engine misfiring or a sudden drop in the acceleration process. To prevent these issues, you have to keep the fuel injectors clean and free from unusual blockages.

Fuel leakage

While driving the BMW on the road, if you are experiencing a strong fuel smell with other issues, then it may have fuel leakage issues. When the fuel injector is accommodated with another fuel injector, the injector is getting old, and they are not maintained properly, then you will notice fluid leakage issues in your BMW X5. On the other hand, fuel leakage has occurred when the fuel is close to the injector and might have a drop on the fuel gauge.

Illuminated check engine light

The common way to determine the failed fuel injector in your BMW is the illuminated check engine light on the dashboard. When the injector is functioning abnormally, the light will come on automatically. In general, if the injector is delivering too little or too much fuel into the engine, then the ECU will trigger the warning light down to a fuel injector.

Stalling engine

When the proper amount of fuel is unable to reach the engine from the injectors, then you will notice that the engine is stalling randomly or cut out without performing any functions. In these cases, the ECU will stop the engine and cause stalling when too little amount of fuel is reaching the combustion chamber. On the other hand, the failed injectors are causing engine stalling and blocked nozzles issues when the injector connects with the fuel lines.

Reduce fuel mileage

Due to the failed injector, the fuel mileage of your BMW X5 is reduced improperly. The reason behind is, the ECU is consuming more fuel from the injector that does not receive it in the combustion chamber. When a low amount of fuel reaches the engine in a leaked or clogged fuel injector, the fuel mileage is reduced.

Rough engine idling

If you notice that the idle noises produced from your BMW have changed and feel rougher, then the fuel injector unable to deliver the fuel as they should. Thus, the outside dust or particles clogged the injector nozzles in your BMW and cause engine misfiring. Subsequently, several problems can cause rough idling noises in your car with a dirty air filter and bad spark plugs.
