There is now a small description in RealOEM.com about retrofitting dynamic cruise control with braking function.

It describes the parts needed and has a reference to the needed coding.

Early Pre LCI cars built before 09/06 (with 544) can retrofit ACC because they have LDM control unit installed.

Info from WDS, "With optional extra 544 (up to 09/06) and optional extra 541 in the E90/E91/E92, the scope of functions of the software for cruise control is implemented in a separate control unit: the LDM control unit."

I already have Cruise DCC option 544 + LDM. After reading a lot about ACC option 541 upgrade I believe the cluster should be the same. Can anybody confirm this?

I want to buy ACC sensor wiring kit but can't find any. Anybody else done some research into this subject?

I suppose the way to find out is to change vo. Then code the kombi module to say acc is installed, then see if the segments light up on turning on the ignition.?

You will need the complete switch cluster with the extra functionality on the cruise stalk which will be a rare find!

I think it's possible to find the ACC stalk with some patience, I'm not in a rush I might also buy newer cluster with led retrofit (they will also code it to my car).

If you want the same function on the 6 cyl, this is also possible without any hardware upgrades

its only when you start looking into dynamic cc, that it gets difficult

But coding a used is poss
You´ll need an autologic, as its the easiest imo

program the DSC
Program the SZL contact (cruise control arm part) to the car under retrofit / CIP
Reallign the steering angle sensor , and job done
Hi,

Sorry for diggin out old topic.

I'm having problems with my 330xd cruise retrofit (02/2006 model).
I have the correct slip ring installed (working, tested through INPA).
As you know, e9x 6 cylinder models came with only 544 or 541 (Dynamic or Active cruise).

----

Post above claims that it is possible to program regular 540 cruise for 6 cylinder - is it true? The parts for 544 are not expensive but i really don't care about the braking function.

We coded DSC and everything else for 544 but we didnt try 540 later on - would this make it happen?

up to 09/2006 - LDM required for CC on 6-cyl
after - it's functions built-in in DSC
braking function is DSC function, so braking DSC is installed on all 6-cyl cars
xi/xd cars also have specific(more functional) DSC module(DXC), built by Bosch and not Continental Teves

Information is a bit controversial...

Mallard above says that regular 540 CC would work on 6 cylinder and i've also found few post from German forums claiming that it is possible.

---

We looked into my 330xd engine soft and compared it to 530xd (2006) engine soft, that was retrofitted with 540. Looks like some important values are different and thus the 540 won't work on my e91.

Theres a slight change that the CC would work by changing these values... Because regular 540 CC don't aquire LDM module.

Sorry, what exactly is KOMBI? Not familiar with everything
I don't do programming myself - I'm just learning by being inside the process.

Last friday we looked into car software with BMW's diagnostics software (can't remember the programs name) and saw that DCC 544 is written into software but inactive (due to missing LDM module).
But there was nothing about regular CC - so adding options for 540 might work (similar to bmw e60 soft)... I guess we will give it a try.

No, regular instrument panel (speedometer), without cruise control arrows/dials.

Point is that 4 cylinder 540 CC works with this kombi - it just doesn't show the fixed speed anywhere. I wouldn't mind that.

Don't know why bmw made this kind on BS.

----

Worst case scenario is: Find LDM and instrument panel - install and program and hopefully be done.

I have'nt found correct part code for KOMBI yet. Maybe anyone knows? They are different for petrol/diesel I know, but for 2/4 wheel drive probably same? On ebay there are few panels from 2007 330d for about 140€.
There is also a lot of info about KMOBI programming - that it might just not work and it would be safer to buy new one from bmw (don't know the price yet).

LDM can be bought from 60-120€ used and 300€ new.

yes, you need try to code 540 option
if it do not help install LDM and replace KOMBI
correct number for KOMBI can be take from realoem or other ETK site, but this not critical
look for those with CC dials and arrows and Diesel word
estonian or latvian private bmw shops adopt any used KOMBI for your car
