Z4 E89 roof motor question

[Lotusgone]

Having been marinaded in three pints of water, the motor needs replacing.
My understanding is that the new unit is not just a plug-in process, but that special software is required to make it work.
Is this correct?

No idea about the E89 but there will be plenty on Z4-forum.com that will know

There are also a number of people on there both business and private who do roof "fixes"
