Tasca's site lists it for ~$35 new so at least it is still a valid P/N:

However, as I have found several times in the past, this doesn't mean the part actually exists.
You could try calling their parts line, they are usually quite helpful on the phone. Oftentimes lately, even they can't tell ahead of time whether or not the part will actually show up, but they are pretty good about trying to track stuff down if it can be gotten at all. It is pretty rare for us to able to get parts here in the US that can't be had in Europe, so if your dealer can't source you one there, I wouldn't be too optimistic about a US dealer being able to get one, but who knows.
Otherwise, I do have at least one good one that you're welcome to have for whatever it costs to send across the pond... my cars have cruise so they are no use to me!
