e90 Front PDC

I currently have rear PDC in my e90 with idrive. I am looking at fitting front PDC on my car as well, I have a bumper with PDC holes in it and will be able to get the sensors, module and wiring for the sensors.

Now here comes my question: If I am able to swap my module which is for rear only, for one that is rear and front. Will be be able to just plug everything in and be good to go? Or will I have to go to the stealer's and get ripped of by their price to reprogramme the car?

So basically will I have to reprogramme the car if I change modules?

Thanks
