I've picked up a E39 which shares its clocks with the E38 I believe(?). It was OK when I looked at the car, but its started to have a intermittent fault with the speedo needle which will sometimes jerk and "catch" while moving round the dial. It doesn't do it all the time, but you can get it to do it while doing the OBC instrument cluster test so to me that rules out the speed sensors?
Makes it a real PITA to drive around town because it will get stuck at 25mph and you'll be doing 35 or w.e =/
Any one got any experience of this or of taking the clocks apart on the E39 or E38?
