The feature, Touch Signaling, is referenced in the 2008 and 2007 owner's manual. It says, if TS is activated, a slight press on the turn signal will be followed by three blinks of the left or right turn signal. My 2008 X3 manual references this, as does the 2007 (on line) owners manual.

The dealer says, they've never heard of it.

What is correct?
