I've just fitted a Westfalia towbar and electrics to the car (Avant) but keep getting a warning of "towbar not fixed". I cannot change, using VCDS, the long coding on the trailer part from Automatic to Retrofitted / fixed? Has anyone else had this problem or know how to solve it without going to Audi?
In addition all electrics work except the brake lights with the bulb out warning appearing on the DIS. Is this linked to the problem above?
All other coding went fine and it's all properly wired up with the rest of the cars electrics OK?
Any help would be appreciated!
