Rev and speedo problems

[Jaymz stealth]

Hello my rev and speedo do not work properly they both sit at a different places after a few days I keep moving them back to
zero and all is fine a few days later with the car off the Rev counter will be at 7k rev or some other place it's compleat random but never in the same place but when I reset to 0 it seems to give an accurate reading the same with the speedo after a few days the needle seems to move lower and lower and tends to stop moving when it's pointing the the stop light but the needle still moves the right distance for the speed I'm doing for example at zero when I go 30 it reads 30 and moved say 2 inches after a few days and it's drops below zero and when I know I doing 30 it reads 20 but the needle still moved 2 inches

I also noticed that when I'm driving nd slam my breaks on so I stop the needle is still falling after I have stopped is there anyone who can help me fix this problem

The instrument panel receives digital data and converts it to drive the dials. I therefore suspect the problem is in the panel, either in the digital to analog converter or the dial mechanisms. It may be that it can be corrected with a good cleaning by a professional.

I suggest you Google "Peugeot 206 instrument panel repair" for some possibilities.
