Issues with Air Conditioner

Hi all,

Enjoying my new Octavia vRS TDI. It's only  3 months old and has around 2000 miles. In the last few weeks I've noticed the air conditioning is not functioning properly.

When I have the AC on auto and it's cooling, the fans will blow cool air for around 1 minute. Then I hear a thumping noise, it sounds like it's on the passenger side of the front vehicle. The fans immediately stop blowing air, but the AC still makes noise.

It's quite hard to explain, so I recorded a video so you can hear:

I cut the start of the video - the AC was running for around 50 seconds before the start of the video. At 6 second mark you can hear the thump. The noise gets louder, but the fans stop blowing air.

If I turn the AC off, but keep the fans on they blow air again, but it warms up as no AC.

I'll likely take it in to get looked at, but just wondering if anyone has had this issue, knows a quick check/fix, or just to give some info for anyone else having a similar issue.
