Looking at buying 2009 C4 VTS. Need towbar for light towing. When googled nearly fell off chair at prices,then read threads here.Realised the cost is in wiring. Most threads I could find are getting a bit old soooo. Has anybody successfully fitted towbar on VTS? For example model from Towbars australia. Is kit truly plug and play or lots of trial and error. Also am not clear on need for dealer reset/activation. Any comments appreciated. Also any general comments on VTS also welcome. Viva la France.
