Hi,

the two videos got my attention too.
As I found out, you need several things vor ACC:
- DSC (with ACC, possiblly with Parking Assist (+) it works too, sadly I don't have it as I only have standard PDC and Driving Assistant non plus)
- SAS (ECU, inside Car, left in Front of the driver seat, present if you have parking assistant+ (?))
- ACC Sensor (ECU is integrated), in front of the grill
- Grill for ACC sensor, Wires, etc
- Buttons for Wheel
- nut sure if one needs a new BDC
- Coding
- Calibration of ACC



Part no for my g31 for Retrofit

As I don't want to mess around with the braking system (DSC) it is no option for me to retrofit it by myself. A germany company (bimmer-manufaktur) offers the retrofit for around 5.000€, so it is possible but makes no economical sense to me.

Hope I could help a bit.

Regards

Actually you information was very useful since there isn't any anywhere else around, at least that I could find.
So yeah, thanks! 
I will probably still look around on TIS and ETK to see if I can get it to work, if no one else has some new information, and if yes, I share my experience so that everybody else can see it.
