I need to get a towbar fitted to carry 2 mountain bikes and have been quoted £1,000 inc VAT by my dealer to have a detachable swan neck towbar and electrics fitted. They also said I needed upgraded engine fans until I told them I was carrying bikes not pulling a 20ft caravan! I believe Westfalia are the OEM suppliers to Audi. Is this right and has anyone had one fitted and at what cost. Price and photo's would be appreciated as I don't really want the rear valance cutting/disturbing if at all possible. I think Witter and Thule do bars for this car but would be intersted to know which make you've all gone for. The car is a TDI non-Quattro in case of any doubt.
