![]() BMW Drivetrain Malfunction due to Damaged Fuel Injectorsįuel injectors inject fuel into the combustion chamber. Which will then clog the combustion chamber causing the engine to stall due to increasing pressure. By using chemical reaction it converts harmful gases like CO, NO, NO2, into less harmful CO2 and water vapor.Ī clogged catalytic converter would stop/slow down your exhaust emission rate, building pressure in the exhaust unit. Drivetrain Malfunction due to Clogged Catalytic converterĪ catalytic converter is a device that cleans your car’s exhaust emissions. Any failure in the high-pressure fuel pump can cause inconsistent fuel supply resulting in random loss/surge of power. It does so by compressing fuel creating high pressure in fuel lines. High-pressure fuel pumps are required to transfer fuel from the tank to the engine. If the drivetrain malfunction error is showing up while accelerating, it can be due to failed high-pressure fuel pump. Drivetrain Malfunction due to Failed High-pressure fuel pump Symptoms like misfiring, power loss, or rough idling of the engine are caused due to bad spark plugs or old ignition coils.Ī quick diagnosis of the engine coil is enough to know if it is the ignition coil or the spark plug at fault. If the coils go bad, less power would be produced resulting in bad sparks. Ignition coils are responsible to provide electricity to spark plugs for the production of sparks. Drivetrain Malfunction due to Old Ignition coils ![]() Note- If you have a diesel-powered engine, it has no spark plugs. So having good spark plugs is necessary for the proper functioning of the engine. This ultimately affects the power produced by the engine. The intensity of sparks produced decides the quality of combustion. Since spark plugs are responsible for the combustion of fuel inside the combustion chamber. In such a case, you should immediately change all of your spark plugs at once. This is generally caused due to the following reasons:- Drivetrain Malfunction due to Overused Spark Plugsįacing engine misfire while experiencing drivetrain malfunction is due to Old/overused spark plugs. While the transmission controls the gearbox ratio to maintain the engine speed.Ī BMW drivetrain malfunction is caused when any of these components fail to function properly. The power generated by the engine is transferred to the wheel through the drivetrain. Why is the BMW drivetrain malfunctioning? While allowing you to get to your destination safely without damaging the car. This helps in preventing any further damage to both the engine and transmission. Under which, your car’s ECU (Engine control unit) limits the overall torque production. In such an event, your car switches into safety mode or limp mode. “Drivetrain Malfunction: Drive moderately. You get this error when your car’s engine computer (known as ECU, ECM, DDE, DME) detects a malfunction in the engine or transmission. What does the BMW drivetrain malfunction mean?Īs stated, the BMW drivetrain malfunction is a hardware malfunction error.

When facing such an error your car would also show multiple symptoms like intense shaking, rough ride, vehicle cutting power, etc. Malfunctions like this are usually caused by intense/abrupt acceleration, steep inclines, or overtaking. This limits the overall engine output saving it from further damage. To protect the engine, transmission, and driver, the car switches into safety mode. The BMW Drivetrain malfunction is an error caused due to a potential malfunction of the engine or transmission. It is not often when you get a Drivetrain Malfunction error in your vehicle. ![]()
