Hello all. Just bought a 2005 q45 and discovered that the automatic wipers don't work. I've done loads of searches but I can't find any information on the rain sensor or where to find a replacement. The service manual only mentions how to remove it and calibrate it.
I removed mine and the "lens" seems to be a single molded piece. See pic. Mine appears to be "crackled". It doesn't seem to use a gel like other sensors.
Does anyone know anything about it or where I can find a replacement?
Thanks
