Twingo C06 gauge cluster/combination meter repair

Car broke. I fixed it.
This gauge thing has like 4 different names depending on where you look but despite the suggestion by the name "tacho" it doesn't have an RPM gauge, just vehicle speed, which apparently is what "tacho" is in German if you ask Google Translate (well, "vehicle speed" is actually "Fahrzeuggeschwindigkeit" which is ridiculous and that would take up like half my title; "tacho" is "speedometer" for some reason while what English calls an "RPM gauge" is apparently "Drehzahlmesser" in German). It's also called a "kombiinstrument."

Very useful video, thank you! I have same car as yours and also have had the same problem for past 10 days. I dissasembled tachometer/speedometer and noticed nothing strange about components, but some insect was touching this yellow foil with contacts and I removed it. Now there is no more buzzing (I tried if it's working properly many times before assembling) and I hope that was the only issue.
