Buzzing Noise on Throttle

[NostalgiaV]

After owning my FL5 for a few months I've noticed a metallic buzzing noise at the upper register when the vehicle is under load. I don't think it's the waste gate actuator as it's very audible whether the vehicle is driving or parked. Where I used to be able to here the turbo spool up, I can't any longer, this new buzzing noise masks it.

I'm wondering if injector noise, the valve train at this point. I was able to compare my vehicle to a like vehicle which presents the same noise under load, however mine is much louder and apparent.

Would love to get some insight.

im not 100% whether it's the wastegate or fuel pump or injectors or all of the above
but mine sounds just like your videos and i would call it all normal

Just wanted to reply here since I found a vid on youtube that perfectly described the sound I was hearing when accelerating and also when letting off the gas, which sounds like what you are hearing too. Apparently its normal, but yeah still annoying. Also im only at 850 miles

Yep, same as I hear. I think what concerned me was that in my first few hundred miles, new, there was no noise. It started happening around ~800 miles in.
