Velocimetro Opel Vectra

Good morning, I have an Opel Vectra 2.0 16V DTI and the problem I have is that the velocimetro and the telling me have been stuck at the bottom, they do not move. Velocimetro tintinea a little and makes a slight noise.
Can you tell me what is it due?
Thanks and greetings.

Regardless of whether the model is a b or c vectra, it would be necessary to enter with the diagnosis terminal in instrumentation and check in parameters if the speed and revolution signals are reaching, and make an activation of the needles.
Possibly it is a problem of the PQ Sin Table you would also have the light of ABS that is where the speed signal and the engine where the revolution signal takes.

All the best.
