Anything as I've no idea about any of it!Are you talking about having a re-gas done?
Anything that needs doing, the general opinion seems to be it should all be okay for now!Are you talking about having a re-gas done?
As far as I'm aware it's all working fine, the next service is in March.Yes, leave the gas if it's working OK.
The filter is part of the mandated service routine.
The issue with this is that if you don't follow the service regime it won't be covered under warranty if something goes wrong. Trust me, if it goes wrong it can cost a huge sum of money to fix especially if it's the compressor. At two years it will mostly be filter changes & check for leaks. Make sure you use the Aircon regularly at least for 10mins each month to keep the seals lubed.If the dealer tries to sell you an air con service, don't take. It's just a way of making some extra cash.
