Have a Telemetrix speedo fitted to my MK using 4-magnet type sensor.

This worked perfectly for SVA etc but since then has barely worked at all...

It worked for a few hundred yards when I drove the car on Saturday before stopping completely. Odometer and its functions work - it's just the speedo that doesn't. Sensor lights-up fine. Any ideas?

Thanks

Are the magnets still there? or has the sensor slipped away from them?

Cheers

If the odometer is working then its counting the pulses. I would gess a back connection inside the speedo hence the intermitant nature of the fault.

Try sending it back to the manufactuerer for repair.
