2001 Mercedes Benz CL500 Audible Ding

Hello. Thanks for the donation. Much appreciated

Check the sensors mentioned below if you have special wheels (low profile) fitted, this can effect the sensors more and cause a warning to sound more often over uneven ground. You could also have the car plugged into a diagnostic computer to check if there are any ABC/BCM failt codes stored on the system.

Check Active Body Control Acceleration Sensors, Replace if Necessary
This Recall Campaign has been initiated because Daimler AG has determined that variations in the suppliers soldering process resulted in soldering points on the board of the ABC sensors which may not be within design tolerances. As a result, signals from affected sensors measuring the acceleration may not be accurately transmitted to the Active Body Control module. A variation in the transmitted values between affected and unaffected sensors can result in one front strut adjusting to a value indicating body movement while another strut does not adjust presenting the driver with an uneven front suspension. A warning will be shown in the instrument cluster if this result occurs. This condition may lead to unexpected body movements at the front axle which can adversely influence the vehicle's directional stability and could lead to a vehicle crash. The dealer will check the production date of the front active body control sensors and replace the front active body control sensor(s) if necessary.
Prior to performing this Recall Campaign:
Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.
Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
Approximately 4,579 vehicles are affected.

This could be causing the warning ding. The dealer will supply you with the model details using the VIN #
