I went for a drive in the mountains today, top down. It was a sunny, dry day, fairly warm for November 1st, though the air temperature dropped noticeably and the road surface was damp on north-facing descents.
After a few miles, I noticed that the multi-function dial (fuel gauge/water temp/oil pressure) had misted up internally. Then a while later, the speedo did the same thing. A few miles further on, they both cleared.
Nothing to worry about, of course, but do they all do that?

A couple of my smaller gauges misted up this morning driving to Cheshire in the fog
It also happened with a few more dials late last year when I set off early one morning in sun after a damp night
It's just moisture condensing on the inside of the cold glass
It will happen to any gauge that isn't completely sealed from atmospheric moisture
I had the same thing happen a few times in a wrist watch where the seal had perished

Lots of posts on this site suggesting fixes but I don't think any worked for long. Funny though how I've never had a clock mist up like my morgan in all the rag tops and motor bikes I've owned over the years. Mine has Smiths clocks which probably was a spin off from Lucas.
Best suggestion was to park with the rear of the car facing any sun that's shining. Someone suggested that should be included in the owners handbook.

A hair-drier plugged into the socket should do the job. Perhaps MMC could design a built in hair drier attached to a ram mount pointing at the gauges.end of problem then.

The moisture condensation inside the instruments is something I never experienced with any other car/bike/tractor than my Morgan4/4. Even the M3W does not have misty dials - but they are VDO production.
Smiths instruments - another example of special craftmanship?

Mine regularly mist up - they did over the weekend... My speedo had quite big water droplets in at one point.
I would have thought that the dials arrive as sealed units to MMC - but I have no idea. I've never had a car or motorcycle do it before.

Mine seem not to suffer in this way.
The car lives in a garage that is attached to the house and is fully insulated. So most of the time it is warm and dry.
Also, when I leave the car hood up I make sure the windows are open. But mostly I have the hood down.
