My speedometer sometimes stops working, but when i tap on the cluster it comes back. It has lead me to think the plastic gears behind are worn out. Can anyone confirm this ? And where can i get new gears ?

I've got the same problem, Check the ground - grounding the speedo wire (from somewhere near the dash) onto a piece of bare metal can temporarily fix this issue. -
if you tap it and it comes back it's probably just the ground connection.Comment

The 'broken gears' refer only to the odometer. You have an electrical issue, not a mechanical issue.Adam Fogg- '88 M3

check the connector on the back also. Mine is missing the black clip on the back every so often if I hit bump just right my speedo will stop workingComment

Could be a broken trace on the PCB also... my tach cuts out like that a lot and that seems to be the only cause left that I haven't checked.

i had the same problem and it was as easy and re-soldering some of the bad joints on the back. I re did mine and now the speedo works great.Comment
