Hello,
I have a 2005 w211 e320 CDI
My car has recently had the rain and light sensor stop working.
The wipers on the first setting work like any other cars, like once every 5 seconds, and the automatic headlight setting (first position) simply is always on.
The command navigation is always in night mode even in bright daylight and direct sun.
The only thing I can think is that I disconnected the trunk battery a few weeks ago to try to reset a seat problem, but I'm fairly certain it all worked until recently. We have had lots of rain lately.
I have tried:
-Cleaning the windshield at the sensor.
-Shining a flashlight at the sensor to try to induce lights off.
-Disconnecting the trunk battery for a minute and reconnecting.
-Taking the overhead module down and disconnected and reconnected all connectors inside, also the connector to the sensor I plugged and unplugged.
I inspected the sensor PC board up close as well as the windshield and plastic optical elements and it all appears to be in perfect shape, I seriously doubt it is the problem. I have ordered another sensor with the same part number and will try that, but I have a feeling the unit needs to be enabled in the SDS or something like that.
Any ideas?
