Modern Mercedes-Benz vehicles come equipped with a rain light sensor. The sensor detects the presence of rain on the windshield and automatically adjusts the windshield wiper speed based on the intensity of the rain, it also automatically turns on the headlights when ambient light reaches a low level.

The sensor requires an adaptation when it or when the windshield is replaced. A sensor needing calibration may set the fault code (B221D49) The rain sensor has a malfunction.

In this video I will review the procedure for replacing the sensor. Once done, I will need to calibrate the sensor using my iSCAN device.
