How Do I Know if My BMW Throttle Body Needs to Be Replaced?

If your BMW has an internal combustion engine (ICE) it relies on fuel and airflow to operate correctly. The fuel system controls the fuel supply, and the throttle body and air intake control the airflow.

The throttle body is an air metering device that sits at the front of the intake manifold.

The air intake can become contaminated and debris can prevent the throttle body from operating correctly, causing premature failure.

The basic throttle body is comprised of an outer housing and an internal throttle plate, which is connected to the accelerator pedal via a throttle cable.

When the pedal is pressed, the cable opens the throttle plate which allows more air into the engine - thus controlling the engine speed.

With new technology, sensors and other emissions-related controls have been adapted to this simple design and now most modern vehicles are fitted with far more accurate fly-by-wire throttle body designs.

This system is controlled by an electronic accelerator pedal, which sends a signal through the engine control unit (ECU) to the motor controlling the throttle plate. This motor operates the plate accurately, increasing fuel economy and reducing harmful exhaust emissions.

Due to the sensitive electronics inside the fly-by-wire throttle bodies, failure can mean a new throttle body needs to be fitted.

What are symptoms of BMW throttle body failure?

Check engine light is on - this is mainly for the electronic throttle bodies. If a sensor fails or detects that there’s a discrepancy in movement between the pedal and the throttle. blade, it will illuminate the check engine light and you may experience a loss in power.

High or erratic idle speed - if the throttle plate has a build-up of carbon deposits or a mechanical failure, a high idle or erratic idle speed may result.

Sticking or racing throttle - if something is caught in the throttle mechanism causing it to stay open, the engine speed will increase. This can be dangerous if it happens when you are driving.

If your throttle gets stuck open, switch off your ignition as soon as possible but make sure to leave it on accessory power so you can steer. This way, you will still have steering so you will be able to pull over without incident

Reduced power and even limp-home mode can activate when there is a problem, and this may cause an accident if you are not ready for it.

Replacing your throttle body as soon as you notice issues will not only ensure your vehicle is safe to operate but will keep your BMW running smoothly and efficiently.

Cleaning the throttle plate at regular intervals can help to prevent any issues from appearing.

The throttle body can fail and may need to be replaced on your BMW at some point, and that’s where AutoGuru comes in handy.
