Coded a friend's 2009 4.8i a few days ago. What a car!! compared to my E53 3.0. Wish I can upgrade to a 4.8 .. too bad it guzzles gas like crazy.
Also love them suction doors! reminds me of an S-Class, very classy!
Anyways, here are some of the codes I did..
power tailgate close via key fob/trunk button
windows roll up via key fob
DRLs and amber side lights turned off
digital speedometer (I wish I had this option on my E53)
fog lights stay on with high beam
double flash hazards.. it's pretty cool haha
turned off the seat belt warning gong but still get the seat belt warning
