PF Jones.  Not too tricky.  Instructions are on their website.  OEM Towbar is a rebadged Westfalia detachable swan neck.  If you can, get one of their OEM equivalent dedicated wiring kits.

You may need to modify your rear bumper if not already fitted with a Towbar.

I would recommend using BMW wiring and trailer module, even if you buy a non OEM towbar. The trailer module does a few useful features:

-if conditions require rear fog lamps to be on, it cuts power to the cars fog lamps, leaving on the trailer foglamps. This avoids dazzle in the mirrors from light reflected off a caravan for example. However, some 13 pin sockets have a pin/extra wiring socket that does this
-in reverse, the PDC gong is de-activated, as it would otherwise operate due to the nearness of the trailer (its very irritating switching off the pdc multiple times, believe me).
-in reverse, the reversing lamps are de-activated as per the fog lamps, but only when the trailer is attached of course.

The OEM system also changes the DSC operation to take a trailer into account.
