It might have to be a process of elimination.

If you think it’s the tachometer and you have an auto, the cable can be separated from the transmission and the centre cable/wire can be removed for greasing. It’s fiddly but no where near as much work should you have a go from the tacho end.

There are several threads on this subject.

It's the speedo

Mine whines whenever I go too fast or try to overtake. Only happens when the wife is in the car though

I think this is a common issue.In my case , greasing nor even changing the cable didn't make any difference.
The problem was inside the speedo (or tacho?) itself.
It had to be removed (not an easy job!) and greased and has been running quiet since then.

My experience is the same as Philmas.............greased the internals of the tach and it has been quiet ever since.
