Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety.
  • Ensure the vehicle is on a level surface with the engine off.
2. Throttle Body Cleaning
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Clean the throttle body using throttle body cleaner and a soft cloth. Ensure the butterfly valve can move freely.
  • Reinstall the air intake duct and secure it.
3. Accelerator Pedal Position Sensor Check
  • Locate the accelerator pedal assembly.
  • Disconnect the electrical connector and use a multimeter to test the voltage output while pressing the pedal. It should show a smooth increase in voltage.
  • If faulty, replace the accelerator pedal position sensor.
4. Fuel System Inspection
  • Locate the fuel pressure test port on the fuel rail.
  • Attach a fuel pressure gauge and start the engine to check the fuel pressure against factory specifications. It should typically be within the range specified in the service manual (usually around 50-60 psi for BMW).
  • If pressure is low, check the fuel pump and filter for clogs or failures.
5. Reconnect Battery
  • Once all checks and repairs are completed, reconnect the battery.
  • Clear any stored error codes using the OBD-II scanner.
