Looked up the O-ring to see what it looked like i.e. to see if it was split as you mention, but even the one on the Audi Tradition site is just a normal looking O-ring. Also checked the size and it's listed as being 11x2.5mm. Going by the dimensions, I'd say the previous image I posted is possibly misleading, as it shows the O-ring being the same size as the grommet, whereas it might be just big enough to fit the hole in the bodywork. Not sure if that helps or not.
