Solution

1. Preparation

Tools Required: Spark plug socket, ratchet, torque wrench, dielectric grease, cleaning brush, compressed air (optional).
Ensure the engine is cool before beginning the procedure. Disconnect the battery to prevent any electrical issues.

2. Remove Engine Cover

Locate the fasteners securing the engine cover. These may be screws or clips.
Use the appropriate tool (screwdriver or pliers) to remove the fasteners.
Carefully lift the engine cover off and set it aside.

3. Access Spark Plugs

Identify the location of the spark plugs. On the BMW X5 G05, they are typically situated beneath the ignition coil packs.
Disconnect the electrical connectors from each ignition coil by pressing the release tab and pulling them off.

4. Remove Spark Plugs

Using a spark plug socket and ratchet, carefully unscrew each spark plug from the cylinder head.
If the spark plugs are tight, apply penetrating oil and allow it to sit for a few minutes before attempting to remove them again.

5. Inspect and Clean Spark Plugs

Examine the spark plugs for signs of wear, such as burnt electrodes or excessive carbon buildup.
Clean the spark plugs using a cleaning brush and compressed air if they are reusable. If they show significant wear or damage, replace them with new spark plugs.

6. Install New or Cleaned Spark Plugs

If using new spark plugs, apply a small amount of dielectric grease to the threads to facilitate easier future removal.
Hand-tighten each spark plug into the cylinder head, then use a torque wrench to tighten them to the manufacturer-recommended torque specification (usually around 18-22 ft-lbs).
Reinstall the ignition coil connectors and ensure they are seated correctly.

7. Reinstall Engine Cover

Place the engine cover back onto the engine and secure it with the previously removed fasteners.

8. Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and secure.
