No speedo

Hi. I bought a 2005 TF a few weeks ago. The speedometer doesn't work and the epas works most of the time even at high road speeds. Very occasionally it doesn't work at all. I've changed the speedo transducer and swapped out the instrument panel to eliminate the speedo itself with no change. Any clues on where best to start checking for wire breaks, poor earths, bad connectors etc?

Thanks

Hi and welcome to the forum.

The speedo works on a digital signal from the transducer, the EPAS then gets a feed from the speedo to work.

No speedo normally means a fault in the signal from the transducer but if the EPAS is working and the speedo isn't it suggests a problem with the wiring connection on the speedo.

One last bit of info required, is the milometer working?

Thanks James. I hadn't noticed whether the milometer was working - I think it is but the tripmeter doesn't seem to be.

If it helps there are wiring diagrams in the drop down menu in the community tab at the top of the page.

Hi again James. No the mileometer is not working. Is that an indication of where to look?
Thanks

I would start by checking the wiring between the transducer and the speedo.

Sorted. Broken sensor wire in the engine harness.
