This is a how-to for those of you who have the very expensive EDC (VDC) electronic adjustable damper control and want to replace with either coilovers or other non EDC dampers. It will cost £2,500 to replace the EDC dampers on all 4 corners and they are only available through BMW.
Now assuming you have replaced all the dampers for new units or coilovers, you will have the EDC warning light on every time you switch on the ignition. You can either buy an EDC defeat kit at approximately £300 which don't always work or code out.
To code out, open the bonnet and remove the ECU box cover at the right rear of the engine bay (it has 11 T25 torx screws). The EDC module is at the back of this box and has two connectors, one white one blue. Disconnect both of them and put ecu box cover back on and tighten screws.
Then connect up your laptop to the zed and load up NCS-Expert. First remove option 2VF from the Vehicle Order (VO) on the CAS using FA_write; then change ECU and FA_write the NFRM.
Now code the DSC and Kombi modules. This is the point that most online forums get to and the EDC error warning still comes on. You now have to edit the FSW_PSW.MAN file using notepad. Search for EDCK_ALIVE_ZAEHLER and then set EDCK_ALIVE_ZAEHLER to nicht_aktiv and search for EDCK_ID_MONITOR and set to nicht_aktiv.
The EDC is now removed completely from the zed and no more warning lights. If I did it again I would be tempted just to change the FSW_PSW.MAN file first and code just the Kombi to see this works before recoding the DSC.
As a precaution or if you want to change back later, take a READ of each of the modules (CAS, FRM/NFRM, Kombi, DSC) using NCS-Expert and then if anything goes wrong you can revert back or reinstall EDC dampers again.
I have non-Idrive but if you have it then this next step may also be required -
If you have the first gen idrive (08) in CAPPL set EDC to nicht_aktiv. / if you have the later idrive in CIC set EDC_CIC to nicht_aktiv
Make sure that you are confident using NCS-Expert before doing this as I do not accept any responsibility if something goes wrong whilst you are coding. There are plenty of guides on the internet to NCS-Expert.

As im having KW V3 installed on thursday i tried coding out my adaptive suspension today. Did all as said in this guide. Unplugged white and blue cable in ecu box. Removed 2VF from CAS and NFRM list and then coded Kombi module lines to nicht aktiv. While in kombi i activated digital speedometer just for fun aswell
. Did not have a DSC module option to choose but found a ZDSC ecu. Reading ZDSC it did not have any mentioned EDC lines in it. Also in CIC module i found EDC CIC already Nicht Aktiv. Anyway the error that popped up after unplugging the cables is gone. Did not go for a testdrive as it was late and left the battery charger to do its thing.
If that error comes back i guess i have to look into updating sp daten files as that may be the cause of me not seeing correct DSC module on my ecu list.
Thanks for the guide! Saved me from buying a 300eur cancellation kit. 15 eur cable and 1-2 hours messing with laptop is quite an alternative.
