EP3 loud whining/grinding sound when accelerating/releasing gas

[YaKoStar]

Hello everybody,

I have a 2003 CTR EP3 , 11500 km and I've encountered a problem that's kind of hard to explain but I'll do my best.

When the car stands still and I release the clutch and gently press the gas there is NO problem, everything sounds fine. But when I press the gas and accelerate to around 4000 rpm and then release the gas so that the car struggles/chops forward, there is a grinding/whining noise that comes with the "struggling". It's very hard to explain but I think it might have to do with the transmission or something.. I don't know what it is. It doesn't sound when I'm driving fast or when I'm on neutral drive and gas. Only when I'm accelerating and release the gas, or when shift down to "engine brake".. Anyone know what it might be? The sound is also getting worse and worse..

Thanks

Best Regards

1st video: The whining sound occurs when I gas on the reverse-gear as well.
2nd video: What I'm doing is accelerating on 1st gear and then just releasing the gas and letting it go forward by itself.

Sorry if my descriptions still are bad. I'm doing my best. I hope the videos help.

Thanks
