Just had the mileage on a set of 200 clocks corrected by a local mobile renault mechanic for £60 so I thought i'd share he details for anyone else looking to do the same. He only lives down the road so the price may be a little different if you're further out but I would definitely recommend him, very friendly guy and used to work at the local Renault dealership. Came over and the whole thing was done within 10 minutes. His contact details are on his website: http://www.autotechline.com/
