Hi all,
I'm so glad to find this thread.
First of all thanks to everyone who contributes.
I live in France, and it's difficult to find information on retrofit here.
So I have a 2009 X6 E71 35d with lots of options (with 544) and wanted to add the Active Cruise control option.
I already managed to do it without any issue on an E93.
For the X6, I came across this
Russian blog which was of great help to me (thanks to Google TRAD...
)
I was lucky to find the complete set in Poland (SZL, FRR, DSC premium ACC and LDM from an E70)
I first changed the DSC module, then installed the ACC radar, then the wiring and the LDM.
I coded the DSC, HUD, KOMBI, JBBF, CIC. Now I can see all the modules in ISTA D and INPA, but when I want to activate the regulator (even when stopped) I immediately have a fault that come.
According to ISTA, I have 2 errors :
LDM: CE6C (Status door sensors, 0x1E1) LDM Receiver, FRM
ACC: D156 Signal Invalid (Vehicle data SF-CAN 3, 0x704) Transmitter LDM
I think the error of the ACC comes from the fault of the LDM. And the error of the LDM comes from that I have a FRM 2 which does not send the signal from the closed doors, which causes an error in the LDM.
For those who have managed to do this retrofit, do you know if we should change a coding in the FRM or if we must go to the FRM3 ?
