I used my M240i last 5 digits on the chassis number it had the heated wheel so it is the correct part number.
By the look of the photos the OP posted he has the covers its the switch he's after.

OP put "Hi all does anyone know the part number for the heated steering wheel button housing?" in their opening post tho, which was why I posted the housing P/N

Have you looked at the photos he posted ?
