[V8FunNaturally]

I am the owner of a 2013.9 ED Coupe M3. While in Europe I remember the central console had more buttons than after the car got re-delivered US side. Is this a US regulation that does not allow those functions ?

in Europe my car had the following PHYSICAL buttons:

-PDC
-sunblinds rollers
-HDC Hill Descent Control
-deactivating auto start/stop.

and now I see only 2.

-sunblinds rollers
-deactivating auto start/stop.

PDC is still working automatically when going in reverse but forward PDC required that button and so is not longer possible.
HDC was a nice feature that regulates the car in steep descents to 5 mph.

Why did they have to remove these ?? FYI I got the premium package.
