why does my BMW 5 Series F10/F11 (2010-2017) have a delayed throttle response?

Solution

1. Preparation

• Gather tools and parts required.
• Ensure the vehicle is parked on a level surface and secure with wheel chocks.
• Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, screwdriver, rags.
• Remove the air intake duct to access the throttle body.
• Spray throttle body cleaner into the throttle body and wipe clean with a rag.
• Reinstall the air intake duct securely.

3. Replace the Accelerator Pedal Position Sensor (if faulty)

• Tools Required: Socket set, torque wrench.
• Disconnect the electrical connector from the accelerator pedal position sensor.
• Remove the sensor mounting screws and take out the old sensor.
• Install the new sensor and torque the screws to manufacturer's specifications (consult service manual for torque value).
• Reconnect the electrical connector.

4. Perform ECU Reset

• Reconnect the battery.
• Start the engine and allow it to idle for several minutes.
• Turn the steering wheel fully left and right to reset the ECU’s throttle adaptation.
• Test drive the vehicle to ensure throttle response is normal.
