Audi A4 B9 AC issues

I've got a strange issue with my car and just wondered if anyone has had the same issue

When my ac is turned on I can feel and hear a vibration noise from the engine. As soon as the ac is turned off the noise goes away

The noise with ac sort of goes away after the ac has been on for a minute

I have a 1.4tfsi with 25k miles on it

Any help would be appreciated

Assuming it's the same design, compressor engages, maybe its got loose pulley bearings or tensioner is little flaky, need to get in there to diagnose.
