my BMW X5 G05 (2019-2024) has a check engine light and low power

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Address Error Codes

• Using the OBD-II scanner, note down the error codes.
• Clear the codes and perform a test drive to see if they reappear, indicating persistent issues.

3. Check Engine Oil

• Remove the dipstick and wipe it clean.
• Reinsert the dipstick, remove it again, and check the oil level. Add oil if low, ensuring the correct type as per the owner’s manual.

4. Replace Air Filter (if necessary)

• Open the air filter housing by unscrewing or unclipping the cover.
• Remove the old air filter and inspect it for dirt and damage.
• Install the new air filter, ensuring it fits snugly and the housing is sealed properly.

5. Test Fuel Pressure

• Locate the fuel pressure test port and connect the fuel pressure gauge.
• Start the engine and observe the pressure reading; it should match manufacturer specifications.
• If low, check the fuel pump and filter for issues.

6. Inspect and Clean Throttle Body

• Disconnect the throttle body connector and remove the intake duct.
• Unbolt the throttle body from the intake manifold.
• Clean the throttle body interior with throttle body cleaner and a soft brush.
• Reinstall the throttle body and reconnect the intake duct.
