my BMW 5 Series G30/G31 (2017-2024) has a delayed throttle response, what’s wrong?

Solution

1. Preparation

• Gather necessary tools and components.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Throttle Position Sensor (if necessary)

• Remove the engine cover (if applicable) to access the throttle body.
• Unplug the electrical connector from the throttle position sensor.
• Remove the mounting screws and carefully take out the sensor.
• Install the new throttle position sensor, ensuring it aligns correctly.
• Reconnect the electrical connector and secure the engine cover.

3. Check Accelerator Pedal Position Sensor

• Remove any panels obstructing access to the accelerator pedal assembly.
• Unplug the connector from the accelerator pedal position sensor.
• Test the sensor with a multimeter to check its resistance and output voltage.
• If faulty, replace the sensor with a new one and reconnect it.
• Reinstall any panels removed during access.

4. Update Engine Control Module (if applicable)

• Connect a compatible diagnostic tool to the OBD-II port.
• Check for available software updates for the engine control module.
• Follow the manufacturer's instructions to perform the update.
• Clear any existing error codes from the system.

5. Final Assembly

• Reconnect the vehicle's battery.
• Start the engine and allow it to idle for a few minutes to ensure proper operation.
• Test drive the vehicle to confirm the repair.
