Tools Required: Socket set, torque wrench, exhaust clamp tool.
Sub-steps:
1. Lift the Vehicle: Use a jack and jack stands to safely lift the vehicle.
2. Visual Inspection: Check the entire exhaust system, including the muffler, catalytic converter, and exhaust pipes for cracks, rust, or loose hangers.
3. Tighten Loose Components: If any exhaust bolts or clamps are loose, tighten them to the manufacturer’s torque specifications.
4. Replace Damaged Parts: If any components are damaged, remove them using the socket set and replace with new parts. Ensure all gaskets are replaced to avoid leaks.

3. Address Engine Performance Issues

Tools Required: OBD-II scanner, spark plug socket, multimeter.
Sub-steps:
1. Scan for Codes: Use the OBD-II scanner to check for any error codes that could indicate misfires or sensor issues.
2. Replace Spark Plugs: Remove the spark plugs using the spark plug socket. Inspect for wear, and replace if necessary with parts specified for the BMW X5 G05.
3. Test Ignition Coils: Use the multimeter to test the resistance of the ignition coils. Replace any that are outside the specification range.
4. Inspect Air-Fuel Mixture: Check the air intake system for leaks and ensure the mass air flow (MAF) sensor is clean and functioning.
