It can be coded, Macht Schnell and KW also sell code delete modules.
If you don't use a module you will have an error light on your idrive / dash. It's not a huge deal; more annoying than anything. I lived with it for 6 months. I just put my EDC shocks back on and my error light went off but then it returned. I'm not sure if it's related but the dealer diagnosed it as a module failure.
