Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

When I switch the air-con on it’s noisy, and feels rough, vibrates , almost mechanical, bearing sound feel, I’ve been told they do that when they need a re gas, is this correct, or could it be the pump/fan etc?
Yes this is my experience. A tin of aircontopup and the required fill hose will confirm this.
These tins are often more expensive at this time of year, but likely you a leak somewhere.
Leaks are often at condensers in the front bumper but given the age of 996 often the lines themselves leak also.
Really needed it yesterday....!!! 32 degrees at oulton park so it was much needed. Have it regassed as others have said which usually involves a leak test beforehand..!!!
When the system detects low refrigerant pressure the AC clutch doesn't kick in, so I don't know how low pressure can lead to vibration. Maybe the compressor pulley or clutch is on its way out? Unless you mean the vibration is at the front/cabin.
I bought one of these from these guys a few years ago. :

Just spotted this though which seems better value for money:

Thanks Alex, interestingly it says on your first link not to add oil, what’s your thoughts? Just go for a top up. It still runs cold but not as good as when it was first regassed after the air con pipes were replaced, it’s just the noise.
Having explored these tin can 'top ups' I decided to get the AC man in a van to come around and regas the Audi with the oil and correct weight of gas. They draw out the refridgerant and pressure test the system with nitrogen. If a leak is found it's £25 as they can't proceed. If not the refill is £80 and took all of 20mins on the drive. If I get another 21yrs before another regas I'll be happy.
Fortunately for me I called to book it last Thursday and I got the first appointment after the bank holiday and the heat wave. He told me he was getting calls, texts and WhatsApp as late a 1030pm on Bank Holiday Monday. The phone never stopped ringing when he was with me. And as Fred Pontin used to say "Book early"
