Firstly I would suggest the speedo connection.

On this I would think either an electronic switch where the old fashioned speedo cable would go or there will be a wheel speed sensor on o e front wheel. It should look like an abs connection but hidden right behind the front hub.

It should throw a fault code tho if the sensor is at fault so maybe its the dash.

I think its an issue on the multiplexing network...do you also have an abs light on.Vehicle speed can be taken from a transducer in the gearbox or from abs via wheel speed sensors.

Isn't that roughly what I said?

almost the same but you missed the multiplexed bit.i was merely looking for a bit more feed back.
