Should You Be Concerned If Your BMW X5 Is Struggling To Accelerate in Mountain View? While driving the car on the highway, the drivers are stepping on the gas pedal for increasing its speed as per their requirements. But, many times you will notice that your BMW X5 is hesitating or accelerating very slowly due to the issues in the emission system. The reason behind the problem is that the combustion engines in your vehicle are designed for delivering the right amount of fuel to the engine and removing the exhaust gases from the car through the exhaust system. For performing the whole combustion process and to propel the car forward, different sensors and components are running simultaneously. When any components and sensors of the system are failed, you will notice that your BMW is struggling to accelerate. So, whenever you will experience that your vehicle is struggling to accelerate especially to go up a hill, at intersections, and merging onto the freeway, try to diagnose and fix the problem immediately for preventing major breakdowns on road.
Reason behind your car struggling to accelerate Due to numerous reasons, your BMW is struggling to accelerate on the streets. The following defines the reasons more briefly:
Clogged fuel injector Thus, the fuel injector is an important component of the fuel delivery system in your BMW which is responsible for injecting the right amount into the combustion chamber through very small passages. Over time, the tiny passages of the injectors are clogged due to the containments in the fuel which will block the fuel delivery to the engine. Moreover, the clogged fuel injectors are not only reducing the performance of the engine, but also your car slows to accelerate and found that the engine doesn't have enough power to move smoothly. Neglecting it for longer will cause other problems in the car such as hard starting, rough idling, and decreased fuel mileage.
Defective fuel pump and fuel filter The main function of the fuel pump in your vehicle is to pump the right amount of fuel from the fuel tank to the engine through the fuel line. If the fuel pump malfunctioned or clogged for any reason, then it will block the flow of enough fuel to the injectors. As a result, your car is struggling to accelerate and sputters and stalls while driving at high speeds.
Like the clogged fuel pump, the clogged fuel filter also causes acceleration issues in your car. In fact, the fuel filter is removing the containments from the fuel which is entering the engine. If it is clogged, then it will restrict the fuel flow to the injectors which can cause slow acceleration in your BMW.
Malfunctioned oxygen sensor All we know is that the engine needs the right amount of fuel to burn in the combustion cylinders for running it smoothly and accelerating properly. Due to these reasons, all models of BMW have an oxygen sensor that can monitor the exhaust emission for analyzing the air/fuel ratio in the combustion chamber and sends the information to the engine computer unit. When the oxygen sensor is failed in your vehicle, the engine doesn't have any idea about the air/fuel ratio in the combustion chamber which may result in either a rich fuel mixture or a lean fuel mixture. Due to these reasons, your car accelerates very slowly even completely pressing the accelerator pedal.
Leaking fuel line and vacuum If the fuel line of the car is leaking, then a huge amount of fuel is drained off. As a result, the fuel injector does not have enough fuel to inject into the engine which is not only reducing the engine performance but also produces a gasoline smell in the vicinity of the car and your car is struggling to accelerate. On the other hand, a leak in the vacuum system is affecting the ability of the computer to regulate the air/fuel ratio in the combustion chamber properly. Eventually, you will find that your car is slow to accelerate or feel like lacks power as well as activate the check engine light on the dashboard.
Failed catalytic converter When the catalytic converter is clogged in your BMW, it will prevent the flow of the right amount of air into the engine. At this point, your car is running hotter than normal and accelerates very slowly. Left it untreated for longer may lead to expensive repairs in your car.
Conclusion If you found that your BMW X5 is struggling to accelerate while driving on the streets of Mountain View, then consult a reputed local mechanic for diagnosing the causes behind the problem and fix it as soon as possible because neglecting the issue for longer may cause dangerous situations on the road.
