MFL Retrofit

[zod1ac]

Hey,

I'd like to retrofit some MFL. But here is also my question:

Do I have to code them after the installation in the steering wheel? Or will they just work without any coding?

Thanks for help!

regards,

PS: I have a BMW 318i E90. :P

Edit:

And if I have to code it, how?

Do I have to use tool32 or NCS oder how?

thanks:)
