Be careful if your dealer does an upgrade to your Cabriolet top motor module. The recent software update renders your Aircap inoperative! Without a patch your Aircap will be unresponsive and the rear seat deflector will act strangely. I just went through this and had to make a trip back to the dealer for a patch. I've run into a few friends with the same issue on a E550.

If you see an upgrade to the roof module on your service invoice run to your car and press the airscarf/aircap button and see if it lights up... if not you will need the patch.
