hi why did they change the speedo if it was working? If the combination meter has not been changed, then this should be changed next.
The the trip and mileometer may be working ok, but the speed signal leaving the unit may be missing. This (cleaned up) speed signal leaving the the combination unit is used by gearbox.
This was the cause with my mk4.
