MysticBlueStorm 0 Posted September 28, 2005 When I bought my C I was told that the speedo head unit had been changed. The history shows it should read around the 130k mark but the replacement unit used only shows 76k. Is it possible to wind it on ? ? ? Quote Share this post Link to post Share on other sites
Supercharged 2 Posted September 29, 2005 Is it analogue or digital? It is posible with both tho... Quote Share this post Link to post Share on other sites
stevemac 0 Posted September 29, 2005 I always thought that the digital ones only had 1 opportunity to advance the mileage - i.e. when it was installed. So far as I'm aware, after this point, no adjustment can be made. Quote Share this post Link to post Share on other sites
