A6 C7 3.0TDI Quattro- Air-con gas leak on twin climatronic system

[bluezie]

The air con is loosing gas, and getting warmer until eventually failing roughly every 3 weeks, so it has a small but significant leak.
Does anyone know of a common faulty seal or component to look at first, before stripping a lot of car down to locate all the components for leak testing?

Get an aircon specialist to look at it not a Kwikfit cowboy someone who knows what they are doing, you need a specific amount of refrigerant and oil which should be downloaded into a vacuum and measured. Not a diy task.

Most common is the condenser. Like bill said need to use a specialist. They can normally find the leak quite quickly as they have special glasses to see where the leak is as the oil has some fluorescent properties.

Ac pressure switch is common
Gas leaks through the terminals.
