hi guys,
i am sorry i didn t posted lately in this topic but there are lots of questions and is very hard to follow/answer....i will try to sum it up what i know and hopefully you can get most of your questions from it
first of all, i did this retrofit on an E70 2008 3.0D with Cruise Control with Braking function and Active Steering.
i replaced the SZL (to have the ACC stalk), the KOMBI (because i found one nice from X5M - downside***** is that you can t get the ACC info on it ->you only can see it in the HUD), the FRM (replaced before for LCI retrofit), used ACC sensor (new bracket), used LDM module
i updated all the modules to the latest sw level (except the KOMBI i think) then change the year in the VO to LCI (or at least one that could accept $5DF) and added $5DF to the VO then coded the car
bear in mint that the process was not that simple and that i did lots of trial and error before getting to the expected result
a wrong combination of date and SA code in the VO will give you an error on NCS so if you get to that, check all the SA coded you have in the VO, one of them might not be compatible to the new date (LCI) you wrote into your VO
there are other (at least) two key points you should have in mind when going for this retrofit:
1. E70 and E71 are not 100% identical cars and you should investigate deeper into TIS for your specific model and especially for your specific year and optional
The ACC requires an ICM control unit (Integrated Chassis Management) or an LDM control unit (Longitudinal Dynamics Management) in addition to the ACC control unit. These control unit are then installed as follows:
In the X6 an LDM control unit is installed as well as the ACC control unit. In addition, there is also another ICM control unit which is not however used for the ACC function!
In the X5 an LDM control unit is installed as well as the ACC control unit.
On all other vehicles, an ICM control unit is installed as well as the ACC control unit.
The Active Cruise Control with Stop&Go function has been available since 2007. The Stop&Go function expands the familiar Active Cruise Control feature by the following functions:

2. the DSC module is only one on the E70 non LCI and two distinct DSC modules on the LCI models from 04.2010 (with or without 5DF)

i will return with more info once i retrieve them
DSC interface error is usually because of wrong coding or because of wrong module but for the retrofit to ACC i still suggest the DSC is not needed if the car had 544 (for non LCI cars i mean)
