how to fix a stuck throttle pedal in my BMW 5 Series G30/G31 (2017-2024)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is turned off.
• Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Throttle Pedal Assembly

• Tools Required: Socket set, screwdriver.
• Remove any floor mats or coverings obstructing access to the throttle pedal.
• Visually inspect the throttle pedal for any visible obstructions or foreign objects.
• If the pedal is physically obstructed, remove the obstruction and ensure smooth operation.

3. Check Throttle Cable (if applicable)

• Tools Required: Pliers.
• If the vehicle has a throttle cable, trace it from the pedal to the throttle body.
• Inspect for frays, kinks, or binding points; replace the throttle cable if damaged.

4. Clean Throttle Body

• Tools Required: Throttle body cleaner, soft cloth, socket set.
• Remove the throttle body from the intake manifold following manufacturer specifications.
• Spray throttle body cleaner into the throttle body and wipe clean with a soft cloth to remove carbon buildup.
• Reinstall the throttle body and secure it to the intake manifold with the specified torque values.

5. Inspect and Test Throttle Position Sensor

• Tools Required: Multimeter.
• Disconnect the throttle position sensor and check for proper voltage using a multimeter according to manufacturer specifications.
• If the sensor is faulty, replace it with a new one and ensure all electrical connections are secure.

6. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and test the throttle pedal for proper operation.
