Well, this morning after a 5 mile drive/park up back in car 2 hrs later it decides to clear itself?!!!

I was going to call into dealer before heading home so it managed to bluff me right to the last.....phew!!....dont think I did anything really apart from yesterday just trying to check mountings appeared normal, I did unclip the surround (by accident) but just clipped it back on. Error was still showing first thing and during drive but possibly its recalibrated itself in that time?.
Anyways, I'm happy and top tip for the day if you get this give it a few days (as had been commented) before talking to dealer about it
