Today I cautiously removed my rear-view mirror because I’ll be installing an auto-dimming version soon. I even took note of the bmw official recommended window temperature. Afterwards I saw these hurrendous bubbles above my rain/light-sensor.
The guy I bought the car from had the windshield replaced like 8 months ago. Does anyone know if this is an easy fix? Or better call the company to see what they can do under warranty?
You need to replace the silicon that sits between the sensor and the windshield, part number 61359856157. It's not a difficult job but because you can mess the silicone up really easily I'd recommend a professional do this. Shouldn't be too expensive to fix...
