The Engine Was Misfiring, and The Car Would Not Start

Engine misfire could also be a potential symptom of drivetrain malfunction. It may happen when the car is just about to start or when you try to create it. An engine misfire shows that the car is not able to handle the combustion properly. This shows that the spark plugs are overused and they are in bad condition.

Suppose your car is recently experiencing such misfires occasionally. In that case, it may be due to a drivetrain malfunction, and it is best to get it checked with a mechanic as soon as possible. 

Exhaust Smoke is Excessive

When there is an excessive amount of exhaust smoke, it often indicates that the catalytic converter is not functioning correctly. This malfunction can potentially result in drivetrain issues. Consequently, excessive exhaust smoke serves as a significant warning sign of problems within the vehicle.

The catalytic converter is a crucial component, and neglecting its issues may lead to further complications. If you observe any of these symptoms in your car, it is advisable to investigate the situation, as it could be related to the afore mentioned drivetrain malfunction.

Reasons for Drivetrain Malfunction

If you know that your car is malfunctioning in this manner, you may also be curious to know why this is happening. There are many reasons for the bmw drivetrain malfunction to happen. We will be going to cover some of them here for a better understanding. 

Overused Spark Plugs 

Overused sparks plugs can be one of the many reasons for the same. It ensures that the fuel inside the combustion chamber is working properly. The intensity of the spark shows the quality of the combustion that is happening inside. 

This combustion shows the power of the engine. A good spark means that the engine is working correctly. Engine misfiring due to overused spark plugs are common in drivetrain malfunction. You may choose to change the spark plugs in case this happens. 

Old Ignition Coils 

Ignition coils provide energy to the spark plugs, enabling spark generation. When the coils fail, power output decreases, leading to weak sparks. Symptoms of faulty spark plugs or aging ignition coils include misfiring, power loss, and rough engine idling.

Performing a swift ignition coil diagnosis can help determine if the coil or the spark plug is the issue. As such, examining the coil before drawing any conclusions is essential.

Clogged Catalytic Converter 

A catalytic converter is designed to purify your vehicle’s exhaust emissions. It uses chemical reactions to transform harmful gases, such as CO, NO, and NO2, into less toxic substances like CO2 and water vapor.

A blocked catalytic converter can impede or reduce the rate of exhaust emissions, resulting in increased exhaust pressure and potentially causing drivetrain malfunctions. Excessive exhaust smoke indicates that the issue may stem from a clogged catalytic converter.

High-Pressure Pump Failure 

If the drivetrain malfunction issue occurs while accelerating, it could be caused by a failed high-pressure fuel pump.

High-pressure fuel pumps are required to deliver fuel from the tank to the engine. It accomplishes this by compressing the fuel and generating high pressure in fuel lines. Any malfunction of the high-pressure fuel pump can result in irregular fuel flow, resulting in random power loss/surge.

Damaged Fuel Injectors 

Fuel injectors give fuel to the combustion chamber. A faulty fuel injector would not function properly, resulting in poor combustion and power loss. Rough idles, engine stalls, vibrations, misfires, and other problems can arise. This is another reason for drivetrain failure.

Low-Quality Octane Rating

If you filled the car with bad quality fuel recently, it might also cause the problem. Usually, you should use 93 or higher octane fuel for your car. If the fuel option is unavailable, you can have an octane booster to enable the fuel rating to reach an appropriate level. 

Now that we have explained what can lead to a drivetrain BMW malfunction, we should cover some other necessary steps. Knowing about the problem and seeing the symptoms is useless unless you don’t know what to do next.
