Hi guys I'm looking for some help or advice on a few issues I'm facing ATM. It started with chirping from around the Cambelt area that I got replaced through warranty they apparently changed chambelt ect but the noise was still their today when I was checking my oil I noticed a very light whiring noise deep in the engine very light so I told my friend to get some revs up and I can only explain the sound as like the most loudest buzzing sound from across the engine I've ever heard honestly its like ZZZZZZZZZZ like a petrol Strimmer exaftley like that only when any throttle is applied then immediately after my ac wouldn't work and the noise kind of went away but now a sort of mellow version and the car is definitely running completely odd very sluggish across the rev range its a dsg and I've noticed the needle ever so slightly jumping out of tempo on full boost it seems (normal) ? But definitely isn't if that makes sense ?. Thanks guys. Oh and on full acceleration the psi goes to around 39 wich is normal and the temps wear normal. Thanks https://youtu.be/rLu6BnHiQkk here is the noise
