Citroen XM Forum

Hi guys a question. Having just aquired another XM and fitted a new speedo cable i have noticed today my odometer has stopped working. Its was working but today my trip said i did 10 miles my odometer said i had done 1... Now is there a plastic gear slipping or ??? is there a repair i can do ?
The car is a 1994 L reg 2.1 turbo diesel auto
Thanks in advance Richard

That does sound like the odometer is internally faulty.
There is no known common failure item in the speedo head, so your options are either strip it an repair it, if possible, or replace the speedo head.
