16VG60 1 Posted October 20, 2003 Sounds like an intermittent deffect in the circuit. There are a number of components that can give these symptoms. Firstly i would check the wiring between the dash display and the gearbox speed sensor. Secondly check the gearbox speed sensor for any fault particularly with the drive pinion. These items being ok would tend to indicate a fault with the printed circuit board, or the speedo head itself. This list is by no means comprehensive, but does serve to highlight some of the causes i have found to create these symptoms. Quote Share this post Link to post Share on other sites
rjm3 0 Posted October 21, 2003 John thanks for a quick reply...Do you know the specs on the speed sensor by any chance? Is there a particular wire or pin on the plug to the dash unit to check the signal ? any help is greatly appreciated...regards Jerry Quote Share this post Link to post Share on other sites
G60Dan 0 Posted October 21, 2003 The guy that had my G60 b4 me had this problem. It turned out to be dodgy earth on the speedo (the bit that goes in to the box) I'll try to get a pic of mine tonight if it helps. Quote Share this post Link to post Share on other sites
