Audi A3 noise

Hi guys, I’m new to the forum and I’m having slight troubles with a noise on my Audi A3 TFSI. When the car is in neutral and with the clutch up, it makes a strange rattling noise, and when the clutch is down, it completely stops! Recently it’s started to make like a bumping sound as well as the rattling, I had the gearbox bearings changed last week and I thought this would solve the problem but it hasn’t!! Any help from you guys would be much appreciated! This noise is starting to bug me!
Thanks
Zach

No they didn’t. They said the clutch was fine as it wasnt slipping or anything. Is it possible to change the release bearing without a new clutch or will it need a new clutch altogether?
