The wiper stalk button is onboard-computer control.
Chances are the comm unit had not changed much in the whole generation of vehicles. But if the airbag connector is passed through it to the airbag, then something important is the airbag connector is not the same on the M59 and the B9 so only the M59/pug 306/Citroen Xsara comm units will work on the M59 column. It's one thing getting the comm unit working to change the computer display and have CC working, but no connection to the airbag means a warning light and no MOT pass come that time.
I would just look for a used one from one of those vehicles, will be about £30 and try it. If it doesn't work, resell it on eBay or return it for a refund. All online purchases can be returned up to 14 days after receipt under the Distance Selling Act 2000.
Saves endless trawling part number lists and other sites. If it's used, has 4 or even 3 stalks, it will work. In fact if you already have the 3 stalks just as my M59 did, you only need the CC stalk and those are all identical. You don't need a new comm unit. But, if you also want the computer control version then you'll have to find a used comm from a model that had the 3 line display and trip computer.
