I'm sitting outside next to my car right now and keep hearing a buzz noise. I drove it over an hour ago and about every 30 seconds to a minute a hear a one second electronic buzz similar to the fuel pump priming but a little higher pitched. Sometimes it does it two or three times in a row, others just once. I popped the hood and it seems to be coming from close to the oil filter. I know our engine circulate coolant and I think oil after turned off to cool the turbo and am wondering if that could failed. About to hook up vagcom and see if I have any codes but figured I would see if anyone has had this noise.
