I have this buzzing problem with my vw citi golf , it comes from the speedo area on my dashboard and happens all the time on and of, the oil warning light comes on but I have checked the oil and it is fine. How do I fix this
Not sure what model your car is,but try checking the two oil sender units,one located onthe side of the cylinder head[gearbox side]and the other on the oil filter housing.Also have a mechanic check oil pressure,should be+-2bar pressure at idle.If everything checks out,including the wiring,try another instrument cluster..Good luck
SOURCE: buzzing problem from my citi golf chico dashboard
the buzzing is most likely the speedo cable ive had a few older cars that do this you might try having someone oil the cable if they can or you can as for the oil light it might be low oil pressure or a bad oil level sensor or even a dirty plug on the sensor

I had this problem too its not the oil but the filter on top of it is a switch that has a plug connected to it what i found is that the seal on that switch wears out and then starts leaking thats when you get that warning all i did was to replace the switch and the sound was gone hope this helps
Get a mechanic to check that the engine is making oil p[ressure. The buzzer is a caution device which warns that there is an oil pressure problem. Beware. Some people will get around this problem by removing the buzzer or disconnecting it. The engine will seize if it hasn't got good oil pressure and you will be spending all of your savings trying to repair it...
