- Restoring the original vehicle ride height.
- Improving overall ride quality and stability.
7. Onderhoud
Proper maintenance helps ensure the longevity and performance of your air suspension struts. While these units are sealed and do not require greasing, regular inspection is recommended.
- Gereelde inspeksie: Periodically inspect the air struts for any signs of damage, wear, or air leaks. Look for cracks in the rubber air spring, corrosion on metal components, or unusual noises.
- Netheid: Keep the suspension area clean from dirt, debris, and road salt, which can accelerate wear.
- Air System Integrity: Ensure all air lines and connections are secure and free from damage.

8. Probleemoplossing
If you experience issues with your air suspension system after installing these struts, consider the following common troubleshooting steps:
- Ongelyke Ryhoogte: Check for air leaks in the air lines or the strut itself. Ensure all connections are tight. Verify the air compressor is functioning correctly.
- Oormatige geraas: Inspect mounting bolts for proper torque. Check for any components rubbing or loose parts.
- System Malfunction Light: If a warning light appears, it may indicate an issue with the air suspension system. This could be due to a leak, a faulty sensor (though these struts do not have VDS sensors, other system sensors could be at fault), or the air compressor. A diagnostic scan tool may be required to identify the specific fault code.
For persistent issues, it is recommended to consult a professional mechanic or contact maXpeedingrods customer support.
