Hi, I saw another thread about this, but it wasn't very explanatory. The speedo in my Mary stopped working this morning after trouble firing up, (We've had -16 Celsius here).
What do i need to look for? And is the sensor relatively easy to replace?

I seem to be spending more time at my local garage than I am at home, not to mention the massive amounts of cash I'm bleeding in the process.

Any help would be gratefully appreciated.

Thanks.
