Hi,

I have an intermittent fault with my speedometer.
Sometimes it works and sometimes it doesn't.
When it's not working, the mileage doesn't increase either!!!
Any thoughts?

{subject line made less vague by including a brief summary of the problem}

Focii suffer from failed speed sensors on the differential housing; cheap - but a swine to do if they're corroded.

Sounds like it could be the vehicle speed sensor (vss) to me - search this forum for 'vss' in the message body and set the time to '< 1 year' and you'll get plenty of info.

Here's a previous post from me on the same subject :

...and my DIY instructions are here :

As your car is of a similar age to mine, your vss might also be difficult to remove so be warned it might not be trivial if you're DIYing it !
