2011 Octavia Mk3 VRS Petrol 

I have noticed the A/C system has become quite noisy (when running obviously), mainly noticeable at low revs, like a whiney sound.

I have checked the accessory drive belt and it has good tension (not loose) although it maybe worn? Quite hard to check belt for wear in situ due to access (40k miles on car)

The only other thing I can think of is the A/C pump bearings etc which will be expensive! 

A/C system works fine otherwise.

Anyone had experience of this issue ?

many thanks in advance 

Hello I had this on my 2010 MK2 facelift. If you do a search you’ll probably find the thread. I think Others had a regal which cured it that would be the potential cheap fix. This is the MK3 2013 onwards section so you probably won’t try much help in here as the issue doesn’t happen on the MK3 as far as I’ve seen.

Thanks ahenners - I will look for the thread or repost in correct section. Some places the Mk2 Facelift is called the Mk3 so I get confused!

Not sure a recall would still be valid all these years later tho?

Apologies it should have said regas but autocorrect on my phone changed it to regal, which may have looked like a typo for recall

Yes I did think you meant recall.

I had my system checked and regassed last summer so its not that. 

And its not that kind of whoosh noise anyway. Its a kind of whine or drone and only at low revs. So its more like a mechanical noise, like belt or compressor pump
