I have a Westfalia 321751 detachable tow bar for my 2006 A3 2.0 TDi Sline sportback. Tried to fit tonight and the plate the electrics socket is on stopped me from sliding the bar far enough forwards for the holes to match on both sides. HELP. Anyone else fitted this had a problem? Looking online this definitely appears to be the correct bar for my car but it wasn't having any of it.
