Odometer failure is a common occurrence with the VDO gages that Porsche used. The problem is that the single drive gear that turns the dials breaks down and falls apart. We now offer replacement gears made out of a stronger material that will repair your gage and get your odometer working again. 


Signs of a failed odometer gear:

  • Speedometer works but odometer does not turn
  • Odometer skips or works intermittently
  • When reset button is pushed, odometer stops turning
