The connector holder for the 13-pin automotive plug was broken off on me. So I drew it in short order, installed it, and it works perfectly fine. What else could you possibly want? The manufacturer behind the VW Group (VW, Seat, Skoda, Audi, etc.) is Westfalia. Westfalia also delivers to Peugeot, Citroen, and others, so it's likely that the holder will work for these manufacturers as well.
