Spurred on by this thread, I decided to address my whining a/c.
I had a look at all of the options here in Dublin and decided to go to a place near me where they had a machine that drains cleans checks and re gasses the a/c system. I googled the machine make and model before I called them (they referred to it by name on the website) and by all accounts it seems to be a comprehensive bit of kit.
When I spoke to the service manager (who is contemplating buying a 996.2) he was able to talk about a/c in a very informed manner. When I asked about replacing the drier and the whine, he said if there is moisture in the system and the drier is overwhelmed, it can cause resonance as the refrigerant is being pumped through, but the wouldn't know for sure. He also advises that the machine would dry out the system and restore the existing drier if it wasn't too bad.
He could do it immediately as there isn't much manpower required so I bit the bullet.
The process took about 90 min. The hook up said machine and it measures the refrigerant in the system. 290g in mine - so that was the first problem. Then it extracts the oil - it was low too. Then it puts in dye and checks for leaks. Then it extracts any moisture - which in my case took a while. Finally it replaces the oil and the gas. All without any human input. The dye is similar to the oil and is left in there for future reference and leak tracing.
Cost €146. Result - silence restored, air noticeably colder, and a happy owner. Confidence that it is done properly.
So if you have a whine, I reccommend a similar comprehensive restoration of the system as opposed to a quick recharge at Halfords.
