Just had a Westphalia fitted to the Touareg. The rear cross member is gone and the tow bar in its place. The towing eye Clive mentions is included but maybe not for every one. The tow swan neck is detachable. Waste of time if you ask me but I had no choice.AsDave A1 says you have to get down on your knees to attach it . It is heavy and maybe as I get more used to it the easier it will become.the 13 pin socket is buried deep and again needs a kneel down but It isn’t too difficult. My fitter, spent about 20 minutes taking through his lap top connected to the cars ECU.
No bleeping when indicating now. If a bulb fails a warning comes up on the dash.
Finally no dealer I know fits tow bars . They bring in an expert and add on 25% or what😢😢
