High pitch whistling noise after acceleration.


Registered User
My S3 started making a high pitch whistling noise after I did some acceleration today. I have tried searching everywhere but can't seem to find a definite cause or solution. It only begins after a few pulls, and goes up or down depending on how fast the car is going. When coming to a complete stop, the noise stops and I can drive "normally again". After some research i've come across this video on YT and its spot on the noise I'm hearing.

Any idea's?

Oh and specs are: Stage 3 running @ 380BHP
- Intercooler upgrade
- R8 coils, and upgraded spark plugs
- Forge blowoff (2 months old)
- Evoms INTAKE

Sounds like someone has left an Alarm in the engine bay

Something sounds loose, or grinding.
Has the belt and pulleys been changed, or are they due?
No clue, ima call audi on that one since I havent done it. It did however had a chain maintenance 40k kilometres ago. I'll try to record it myself, but it happened only 2 times and everytime I want to stop to record it, the noise stops and everything is "ok" again. Thanks!
