Dash problem !

[Chamorange]

Hi,

Have a problem with speedo in that it's very stud dish to move on the start-up sequence and never gives the same ready at the end. Often gives speedo error.

Dash ECUi is just back from repair, swapped the ribbon cables round but still the same problem.

Stepper motor also sounds very noisy.

Thing it needs a new stepper motor but who check it and do the repair ?

Also last question, does the little ventilation fan run all of the time?

Thanks

Ian
