Hi all, I have noticed a high pitch chirping on my astra gtc 1.6 turbo, it only happens when the engine is near normal temperature, when I accelerate it's ok, once I slightly ease off the accelerator just a bit I get this chirping noise, nothing on acceleration though.does not happen whilst idling, pressing clutch pedal or brake does not alter the noise.had belt changed but no difference,the mechanic checked everything and he is baffled.the car runs and performs as it should, there are no oil or water leaks.the noise is so annoying, it's like I have 10 birds in engine
