W210 Speedometer

[abecketts]

Noticed today that when accelerating the speedometer "hand" (if that's the right word) moves up as a secondhand on a clock would do in regular graduations. Is this indicating something is wrong or do they just do that sometimes?

When decelerating it does not do this.

Any ideas folks?

Thanks

The one in my 208 did that but only when the interior was hot.
I guessed it was just sticking and never got round to sorting it.

My old 210 did that, too. Got progressively worse over a couple of years, so I had a new cluster fitted eventually - that fixed it!
