• Wait for about 10-15 minutes, then reconnect the terminal and start the car. This process may help reset the air suspension control module.

6. Diagnostic Scan (Advanced): Use an OBD-II diagnostic scanner capable of reading Mercedes-Benz-specific codes to scan the air suspension system. This can help identify specific errors or faults that need addressing. Some models may require clearing stored codes to reset the system properly.

These reset methods are generally applicable to the Mercedes-Benz S550 and other models with AIRMATIC or similar air suspension systems. Refer to the vehicle's owner's manual for specific details and warnings related to your model.
