Turns out that Skoda changed there towbars for mid 2014 onwards compared to the ones they had for release in 2013. The wiring has changed 3 times. Once with each Towbar and agin in 2015. Seems westfalia have not cought up in Aus as the only offer the 2013 version.
Have comm6acted westfalia and waiting a response. Think I'll just get a refund and buy the genuine Skoda one and fit it myself....again.
