I've had my '10 plate Mk6 GTI for a couple of months now. It probably needs some preventative maintenance done like timing chain tensioner etc., but there's only one real problem with it right now.
The air conditioning is really loud. Makes a horrible groaning sound especially noticeable when the car is at idle. Seems to be the compressor as it will be intermittent when the AC isn't doing much on a cool day. Also stops straight away when I disable AC with the button.
According to the service book the car hasn't had an aircon refresh since 2012, but could this cause bad noises?
I'm thinking either the compressor or just the clutch is shot. Is there anything I can try at home? Thinking of taking it to a local specialist soon but would be up for trying to fix it myself.
