Isn't this a repost????

The Speedo is delivered via a sensor on the Gearbox I think...it pulses a voltage depending on speed.

I attach some information that may be of use...there is also a test (Test D) that you could try....

Have you tried a tap or thump ? Technical adjustment as per SAS vehicle handbook.
