It sounds like a humming sort of grinding sound coming from what sounds like the intake it only does it when the car warms up but if I press the gas it will stop then start back up when it hits idle again the car is stock except for a slp MAF censor the previous owner installed. Its a a4 model and it runs perfect no issues with the tranny just this annoying noise

Its not throwing any codes it started doing it about a week ago when temp dropped to freezing since then I've heard it a hand full of times but the weather is still cold I recently changed the oil about 3 weeks ago and used the recommended 5w30. Would that be the cause is the oil is to thin in cold weather
Im having the same exact problem..its like a whirring sound coming from the intake..it happned after the freezing weather ..my 2000 z is all stock besides exhaust...maybe intake clogged??? Having trouble breathing??..im gonna take off the intake this weekend n give it a good cleaning...see if that helps..
Most likely your hearing the valve train. It's all on top of motor and at idle the sound is much louder. Keep a eye & ear on it if it gets worse then some more checking is in order
