Weird functions on 2011 S550

Hello All,

On some occasions, I don’t know what I am doing, I get some power functions that I am not usually able to activate.

1. power windows opening from outside by touching door handle somehow (I know I can close them but opening seems to only happen sometimes)
2. rear window opening with shade screen still up (only happened once before)

are these malfunctions or features I don’t know how to access?

2 is a fault - see if there is a door module software update
1 will be in the manual and is a feature to get the heat out - it will be something to do with how you are using the remote and the door handle (or a fault, try new batteries in the fob)
