I have a problem with my wife’s MX5.

On hot days, when the cars been standing (roof on), as soon as you pull away, in first, the speedo reads 60+mph. On the dual carriageway, it goes all the way round to 40 again!

On cold days, it’s fine.... normal.....

It’s a cable driven speedo.... any ideas?

Time for a new speedo head methinks. Contact some breakers?

What model ?

I'm guessing Mk2 with electronic drive.

It's a Mk1, I'm sure it's a cable driven speedo.
