Just looking in the manual (Page201) and the dipped setting can be changed to offside. It recommends that only a dealer should do this. Anyone had experience of this. I’m guessing a dealer would charge like a wounded rhino!
caldy has a Rosstech lead and I'm bringing my PC hopefully at that time with Rosstech software on board so we should be able to change it ourselves. Otherwise try an independent if you want it done before you get on the chunnel; I got quoted £20.
