Finally bought a replacement for my trusty petrol Mk1 A6 Avant SE 2.0 8v. This time we've plumped for a 2001 A6 Avant SE 1.9 TDI (130). However, it doesn't have a towbar at present so I need to get one fitted within the next month. I really want a detachable one and am thinking it'll be easier to go for single plug electrics for when we change the van possibly next year. Does anyone have any recommendations for the different bars available eg, Westfalia, Bosal, Brink etc and a good reliable (and competitively priced) fitter in the South Yorks/North Notts area. Also, the car has park sensors - a friend with one of these cars says he has to fiddle under the bumper and disconnect one of the sensors to kill them when he has the van attached. This sounds a bit drastic, isn't there a suitable wiring kit that isolates them when the 'van is plugged in?
