Can anyone help with this?
It sounds like an insect buzzing and is very irritating.
I have taken the bonnet off and looked under the dash and though it is very hard to tell because nearly everything is black I can't see anything obviously loose.
A search of posts and Google reveals some comments about the heater and the wiper mechanism as possibly culprits though I get the impression they are slightly lower frequency than our anoying buzzing vibration.
Could it be an indicator buzzer?
When does it happen... does the ignition need to be ON and does it then do it all of the time?

Does it happen at a particular RPM? The wiper buzz seems to occur at around 2500rpm. Ask me how I know this....
Have you found an elegant way to stop the irritating buzz from the wiper mechanism ?
Slowest of the slow.
Doesnt say whether the noise occurs constantly while driving (or at a certain engine revs maybe) or when an electrical item is switched on.
On mine I get a buzz from the dash at certain revs. If I press the ally between the speedo and rev counter it stops. New dial rubbers are on the to-do list along with looking at attaching rubber trim on the ends of the metal clamping brackets for all the dials.
#4, sadly not. It's on my list of things to do, but as it will involve contortions to get under the dash I've been putting it off.
It is a mechanical vibration.
Over the weekend I tried to isolate it and It reduces a lot if I reach under the dash and put a thumb on the wiper linkage.
So It is either that or something close to / attached to it.

I think it is either the wiper mechanism or something close to it or attached to it. The weekends investigations show that thumb pressure on the linkage reduces it a lot.
It is noticeable at just under 2000rpm to about 2500rpm. Unfortunately an 30mph limit puts the engine right on the maximum resonance.

I read another post where the owner filled the mechanism tube up with grease.
I have wondered about a spring or weight to preload the tube just enough to stop it vibrating.
Chris and Kate
It is worst at about 2000rpm and drops of at higher revs up to about 2500rpm.
It sounds like a mechanical vibration and I suspect the wiper mechanism as light thumb pressure on the tube reduces it a lot.
I suspect it is either the spring-drive in the tube or something close to / attached to the wiper mechanism.

Hi, Check the 2 screws that hold the two center lift the dot poppers on the top of the dash, they seem to work their way loose and make a buzzing sound.
