hi , we are expirencing the same issue here
The vehicle (e91 ´05) without cruise control and without multifunction
The customer wants specificly
1) Multifunction system / Msportwheel
2) Cruise control with dynamic (speed control) function.
BMW is contacted for the info regarding setup
The parts list was as follows
New cluster (for vehicles with cruise / dynamic / active)
New control unit (with the new arm for controling the cruise)
New dynamic module which handles the speed contant on inclines and declines.
New cover for the underside of the column to accomodate the new arm from control unit
-
After fitting the cluster and control box, the mechanic discovers that the dynamic box cannot be connected?? and that the car isnt preped from the factort for SA544 or cruise with dynamic function....
So after a lengthy talk with BMW, we discover that the car needs to be fitted with the wiring to acccomodate the dynamic module (an 18 pin connector and wires to go with it...) and after finding the complete wiring schematics frm BMW´s WDS wiring diagram server, we now have to build the net for the car.
BUT !! thats not enough .. then once the car is prepped, you need to buy a BMW farzug auftrag , basically a access coding that initialises the coding for the units. THEN you have to code the whole car to accept the new parts...
Seriously, if i knew how much effort it was to do this .. i would never had said yes to doing the job.
It is almost impossible, but BMW say that this is normal for cars built pre ´06 ?
