Duff Ignition Coil resets dashboard computer?

This has happened to me twice now.

One of the ignition coils fails. Not a serious problem in itself, easy to diagnose using traditional (i.e. non computer) methods; replace the coil , and all is well.

But, after fixing the ignition fault, the dashboard computer no longer indicates mpg or "miles till empty".

A visit to my local independant with a diagnostic computer, a reset of the dashboard computer, and once again all is well.

This has happened TWICE, so I don't think it's a coincidence.

My question is, surely a failure of an ignition coil should have no impact on the dashboard computer. Is this a software "bug", or has Renault built in a requirement to reset the computer (at great expense) following a minor fault?

Has anyone seen the same symptom?
