hi
epb actuator/motot don't need coding
but the module does if its brand new, used one will usually work if it off a similar car, like both auto or both manual, if its off a manual and fitted to a auto, or the other way round the module wont work, because its looking in the wrong place for signals
just remember to either disconnect battery or epb module completely, so you get the park brake calibration message on the dash, otherwise, the hand brake wont work properly and could end up with faults or excessive pad wear
cheers
