The rear bulb warning message may be displayed on Mercedes-Benz ML320 BLUETEC

The rear bulb warning message may be displayed even if the rear bulbs appear to be functioning correctly. This can be caused by a poor connection between the bulb housing and the socket. Our technicians recommend to "hard wire" the socket to the housing, eliminating the contacts as an issue.
