DrphTa 5 Report post Posted April 7, 2011 So I had a workshop pull my power steering pulley out to get me nowhere. - Beside the point Now my OBC isnt calculating properly. Range, speed, consumption & temp do not change at all. On the drive home my Cluster, AC unit, window switches all were not lit. The back light had gone but the gauge works fine. So do the switches and AC etc. The odometer & OBC are still bright and they pulse with the headlights on Have checked fuses and the earth. Any suggestions?

BM WORLD 1265 Report post Posted April 7, 2011 check the dash dimmer is not turned down , or sometimes they fail . also check the fuses and the battery terminals around the fuse box also the earth strap bolts are tight etc Quote Share this post Link to post Share on other sites
DrphTa 5 Report post Posted April 8, 2011 Yea definitely not turned down as the back lighting went out when I was driving. Fuses are all fine and so are the grounds The grounds I know of are both the suspension towers. Drivers sider under the positive feed from the boot and passengers side on the headlight side. Is there another engine ground on the underside by the steering rack? Quote Share this post Link to post Share on other sites
DrphTa 5 Report post Posted April 8, 2011 Even if the bulb or dimmer has gone my OBC screen is still perfect. My range, consumption and speed still do not work but my outside temp does? Quote Share this post Link to post Share on other sites
