I was wondering if there is coding for the e63 , I only know of one is DVD in motion,I would like to close the trunk with my key fob. Here is a list that was done to my 2015 BMW 535xi, it took the guy about 1 hour for 150 bucks .
I know a lot of this list doesn't coincide with the Benz just wanted to give you an idea what was done.

Wanted to email you a recap of what we have done


Front Seat belt chimes/ reminders removal (option to code the driver or passenger's seat or both)

Initial triple-gong removal (sounds after engine start if driver's seat belt is not already on)

+ reduced folding delay to 0.5 second

I looked into this as well a couple days ago and from what I found Mercedes has made it next to impossible to code.

 

I know several of those items are accessible through star.

 

The wonderful world of BMW coding, I miss that greatly. I left it all behind for torque, wish Benz could go as deep into coding and as easy.

 

I do have a guy but I can't get in touch with him I asked him awhile ago he told me that he can do a few things the only one I remember is DVD in motion

I think I'm in the same boat as you,I would leave the coding for the torque and the sound ,when I find out the things he can do I will post it , He will meet anybody in the ny area very cool guy , I hope I can reach him
