- Raise the vehicle using a jack and support it with jack stands.
- Examine air springs for any visible cracks or leaks.
Replace Air Springs if Necessary:
- Disconnect the air line from the air spring using a specialized tool.
- Unbolt the air spring from its mount and remove it.
- Install the new air spring by reversing the removal process.
- Ensure all connections are secure and torqued to manufacturer's specifications.

3. Inspect and Repair Air Compressor

Test the Air Compressor:
- Locate the air compressor assembly, usually found near the rear of the vehicle.
- Check for electrical connections and ensure they are secure.
- Use a multimeter to test the compressor's voltage supply while activating the suspension settings.
Replace the Air Compressor if Necessary:
- Disconnect the electrical connector and air lines.
- Unbolt and remove the compressor from the mounting bracket.
- Install a new compressor, ensuring all connections are tight and secure.

4. Calibration and Resetting the System

After replacing components, use the Tesla diagnostic tool to recalibrate the air suspension system.
Follow the on-screen prompts to complete the calibration process.
Perform a thorough visual check to ensure all repairs were successful.
