For BMW 3 Series Estate, E91 (not 330/335) 2005 - 2012.
Exclusive to Witter this detachable flange neck offers all the versatility of a fixed flange towbar whilst leaving very little of the towbar visible when detached. A 50mm towball is still bolted to a two hole faceplate that also allows the fitting of accessories such as towbar mounted cycle carriers or bumper protection plates. As you will detach the neck when you are not towing this version will not set parking sensors off. When fitted it has a safety lock feature to give a visual indicator of correct attachment and it can also be locked to prevent theft.
