How To Deal With Your BMW Drivetrain Malfunction in Pontiac? An Expert's Opinion

Now modern cars like BMW have more advanced features with a self-monitoring computer system that can easily recognize the problems or malfunctions within the car. Moreover, the warning lights on the dashboard can alert the driver about the current problems in the car for preventing further damage.

Among the several problems in the BMW, the failed drivetrain is the most serious one that can need an immediate diagnosis for preventing expensive repairs. When it happens, you have to consult with a reputed auto repair shop nearer to you for proper diagnosis and repair.

What do you mean by a drivetrain?

In general, the drivetrain is an integral part of the BMW that contains a series of components like a driveshaft, transfer case, transmission, and axles for transferring the power which is generated by the engine to the wheels. In this way, the generated engine power is provided to the car to move forward or in reverse by propelling the wheels.

Thus, the transmission in the drivetrain is changing the gearbox ratio to constant the engine speed because the engine and wheels are rotating at different speeds. All we know is that the drivetrain is a collection of components, so when any component is malfunctioned, it stops working and breakdown entirely.

Reasons behind the drivetrain malfunctioning

Through a well-functional drivetrain, the generated engine power is transferred to the wheel and maintains the engine speed by the transmission. Due to numerous reasons, the drivetrain of your BMW malfunctions. The following points define the reasons more briefly.

Damaged high-pressure fuel pump

The main function of the high-pressure fuel pump in your car is to transfer the fuel from the fuel tank to the engine by creating high pressure in the fuel lines through the compressed fuel. When the high-pressure fuel pump is damaged, you will notice that the drivetrain is failing and showing errors during acceleration due to the lack of consistent fuel supply.

Failed fuel injectors

Thus, the main purpose of the fuel injectors in your vehicle is to inject the right amount of fuel into the combustion chamber for a smooth combustion process. If the fuel injector is failed, then it will cause major problems such as loss of power, engine stalling, rough idling, vibrations, misfiring, affecting the combustion process, and more importantly, malfunctioning the drivetrain.

Overused spark plugs

The spark plugs are responsible in your vehicle for providing the spark needed for the smooth combustion process. Unlike the other reasons, overused or old spark plugs also cause drivetrain malfunction that needs immediate replacement of the spark plugs. Neglecting it for longer will affect the power produced by the engine for proper functioning.

Clogged catalytic converter

Moreover, the catalytic converter is an important device in your BMW that can convert the harmful gases of the exhaust system into less harmful gases and water vapor. When it is clogged, the exhaust emissions are building pressure within the exhaust unit that can slow down the exhaust emission rate. As a result, the drivetrain is affected and causes engine stalling.

Signs of malfunctioned drivetrain

When the drivetrain of your BMW malfunctions, you will notice the following problems while driving on the road.

Bad vibrations

If the drivetrain of your BMW is failed, you will notice excess vibration while driving the car on the road with a clunking and grinding noise. So, when you will hear clunking noise during changing the gears, ensure that the drivetrain needs immediate repair/replacement.

Intense shaking

Due to the failed drivetrain, you will experience intense shaking when you change the gears. When the components of the drivetrain loosen, they will shake more and more. Left it unchecked can fall the drivetrain entirely.

Transmission fluid leaks

If you notice that the transmission fluid is lowering down or leaking, then ensure that the drivetrain malfunctions because the fluid can keep the transmission cool and lubricated. Over time, the leaks can damage the transmission completely and need immediate repair.

Way to deal with drivetrain malfunction

When the drivetrain of your BMW malfunctions, you have to first determine the problem within the drivetrain by using an OBD II scanner. So, it's always to consult with an expert auto technician for determining the causes behind the malfunction instead of trying on your own for fixing the problem.

Thus, the mechanic will suggest the next step for repair and replace the malfunctioned drivetrain if required. For avoiding further damage to the drivetrain, you have to practice good driving habits.

If you found that the drivetrain of your BMW stops functioning while driving on the streets of Pontiac, then consult with a professional local mechanic for diagnosing the causes behind the damages and fix it as soon as possible.
