DEC Retrofit

hamouess · 11-11-2023, 11:38 AM

Hello, on my BMW, X3 F25 manual transmission, I did a DEC retrofit. I connected Pin 11 icm to 4 Dec and 10 to 5. I coded 4U2 in FA but nothing, the switch does not work. I do have the sport mode in the screen settings but the eco mode is not available even if it is coded. I think I need to change the module but that's not what interests me. Do I need to code anything else to be able to commission the DEC? And the connections are correct for you? DEC works like PDC activation.
Thank you

After some research, I saw that it was the ICM module which was too old, I am going to order one and take advantage of it to activate the eco pro mode.
I hope the switch works.
On the forum we only find retrofits with automatic transmission and not manual.
Could this be my switch? because it is marked eco pro/sport and not comfort/sport?

If one day it can be useful to someone, we must add 2VL to Fa and code ICM.
