Is Your BMW Struggling to Accelerate? Here are 5 Possible Causes

The performance related issues in cars like BMW generally happens due to lack of care and maintenance. In this article, you will know about a common performance issue, and that is the car struggling to accelerate. Imagine you are in a hurry and you have to reach your destination in time. For that you have to increase your speed at once. But you feel irritated when you find that even after pressing the gas pedal too much, your car is refusing to accelerate or accelerating very slowly. You must know the causes behind such problem.

What causes very poor acceleration in BMW?

There are many causes of poor acceleration in cars generally. But here you would know all those most common culprits in BMW.

Low fuel

Fuel is necessary for running of the vehicle. Fuel is the most necessary input of the car. The power generated from fuel is used to rotate the wheels and making the car run. So top up of fuel when the fuel gauge indicated low fuel is necessary. A fuel gauge shows the level of fuel in the fuel tank. If you fail to top up the fuel, then no acceleration of the car is certain.

Faults in the fuel system

Even if you have sufficient fuel in the fuel tank, but the delivery of fuel to the engine is not going properly at all. The delivery of fuel to the engine is done by the fuel system. It consists of fuel pump, fuel filter, fuel injector, etc. The fuel pump pumps the fuel to the engine. If the pump is worn or clogged, then supply of fuel in proper amounts to have a right type of fuel and air mixture will not be possible. In sufficient fuel in engine cannot make the car run with enough power.

Damaged fuel injector

A fuel injector injects the fuel with pressure. But the fuel injector is likely to get damaged due to aging and wearing. Sometimes, it may get clogged, blocking the passage of fuel. A damaged fuel injector can lead to leakage and spilling of fuel outside the combustion chamber. This leads to wastage of fuel. The shortage of fuel in the engine makes the acceleration very poor. This basically happens when the fuel has many impurities or the fuel filter is clogged.

Clogged fuel filter

Fuel always pass through the fuel filter and then to the engine. The filter traps the impurities in the fuel and prevents the impurities to get to engine and produce more toxic smoke by burning of the impurities. Gradually by trapping the dirt from fuel for a long time, the filter gets clogged. More the filter gets clogged, more the flow of fuel is restricted. The trapped impurities block the path of fuel, and engine runs with a very low fuel and hence produces a very less power.

Faults in the exhaust system

The exhaust system carries out the burned gasses from the engine to outside. It also has a very important role in maintaining the efficiency of the car. Exhaust system prevents the unburnt fuel vapors from getting wasted. Catalytic converter in the exhaust system converts the toxic gasses from engine into a very less toxic gas. If the exhaust system is clogged or damaged, then loss of power through exhaust leakage is obvious.

The head gaskets damaged

The head gaskets prevent the coolant from flowing to the exhaust or the combustion chamber. If the head gasket is damaged, then it allows the coolant to flow to the exhaust systems. Due to the leaking of coolant to the exhaust, two harms to the car happens, one is production of white smoke and second is loss of output power.

Conclusion

If your BMW is accelerating poorly, then you can use an OBD2 scanner to read the codes and easily know the exact cause of the problem. Check the air, fuel and oil filters properly. The older or the clogged ones are to be replaced. Then the spark plugs are to be checked. To make the car accelerate well you have to always check top up the fuel and oil regularly.
