Yes, I am well acquainted with that function.

After windscreen replacement, the highest speed is now similar to what the slowest speed used to be with the old windshield. At anything more than a drizzle, it is far too slow.

The dealership claims ignorance of any way to adjust said speed.

The BT tool has a reset option that forces the computer to do a calibration.

Variations in glass transparency affects the sensor's output, so new windscreen allows the opportunity for the rain sensor to no longer accurately detect the weather.
