We bought a brand new LHD Xtrail in January, (we live in France) and 2 weeks later a farmer took most of the passenger side off with his tractor. He didnt stop, but chasing a tractor was no big deal and he apologised and a repair was done through the insurance. All is good, other than a red square that appears on the passenger rear view mirror when reversing. I assume they put a wire in the wrong hole, or there is a wire hanging loose inside, but any ideas? The repair was done by a Citroen garage and they just give a Gaellic shrug and evade giving any positive answer.
