Here are the steps on how to lower a 2003 Mercedes with airmatic suspension:
Park the vehicle on a level surface. Turn off the engine and allow the suspension to settle for at least 5 minutes.
Start the vehicle and let it idle for a few minutes.
Connect a diagnostic tool to the vehicle's OBD-II port. Select the airmatic control unit from the diagnostic tool menu. Adjust the ride height of the vehicle to the desired setting.
Save the new settings and exit the diagnostic tool. Once you have made the necessary adjustments, the vehicle will automatically lower to the desired ride height.
It is important to note that lowering the ride height of a vehicle with airmatic suspension may affect the handling and performance of the vehicle. It is recommended that you consult with a qualified mechanic before making any changes to the airmatic suspension system.
Here are some tips for lowering your 2003 Mercedes with airmatic suspension:
Start by lowering the front of the vehicle by 1 inch.
If you are satisfied with the ride height, you can lower the rear of the vehicle by the same amount.
If you are not satisfied with the ride height, you can make further adjustments in 1/2-inch increments.
Remember to test drive the vehicle after making any adjustments to ensure that the handling and performance are still acceptable.
