Do I need an AirCon refrigerant change?

I just arranged a service for my L405 as it will be 3 years old shortly.

The dealer suggested that I have the AirCon serviced which involves replacing all the refrigerant at a cost of £250! Apparently the refrigerant in the L405 is much more expensive than in older vehicles.

This is not something that Porsche have suggested on my Boxster or BMW on my Cooper S so my question is whether it has any advantages and, also, do JLR include it in their service schedule?

Tis a very expensive Gas in the L405's I'm afraid...

Ive just spoken to my AC "Man" and the industry standard is now every two years!!! Due to refrigerant loss & moisture gain! "from an environmental stand point, it takes more of your engines power to refrigerate the air after 24 months" therefore harms the environment... Confused

I hope/suspect prices will in future come down as more widely used . Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

Why change the refrigerant if the ac is working correctly?

From where does it gain moisture, the refrigerant must be in a sealed system.

Perhaps it has to be changed to cover up the smell of bullshit. letters not necessarily in the right order

No need to change refrigerant.

One replaces refrigerant after securing a leak.

The dryer will remove any moisture, of which there shouldn’t be any, if the system was commissioned correctly.

Out of interest, the system is vacuumed (during commissioning or after fault rectification) not only to check for leaks but to also “boil” any moisture to allow for easier evacuation. Sometimes the moisture can be seen to freeze, if there is a lot of it (say in a very humid environment). Pressure is raised (or heat applied) to allow this to melt.

Hmmm, I digressed a bit.

If it works. Leave it alone.

If you were that way inclined, you could record the HP pressure with an IIDtool every once in a while to monitor for pressure loss and hence a leak.

I’ve worked on AC systems for 25 years on ships and I’ve never heard of changing refrigerant as a maintenance measure. 2007 3.6 TDV8

Why would an AC system have a "drier" if there were no moisture to dry??? Whistle

Unfortunately, it is nigh on impossible to achieve a perfect vacuum and remove all traces of air (which carries the moisture) from the system, during the time allocated for initial “commissioning”.

Any debri, say welding slag or just dirt, will eventually be caught in the drier, which has the dual role of “filter/drier”, during system operation.

Moisture can get into the system when a technician connects his gauges and doesn’t purge enough, though 2007 3.6 TDV8

I thought the drier dehumidified the air being blown in to the car not the refrigerant. letters not necessarily in the right order

My air con home unit gained moisture from the copper pipes being a little gas permeable. The proliferation of cheaper copper pipework allows moisture in according to my service engineer.

another way of saying it: Chinese copper
Not outside the realms of possibility.

I guy I know knocked out three teeth because his cheap
(i.e. Chinese) mountain bike snapped it's forks.

I'm no metallurgist though.

Personally I would wait until you notice a difference with the a/c temp and do it when needed 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

Given the pressures inside the refrigerant pipework relative to outside air I would have thought any gas migration including moisture would be from the pipework outwards not inwards. Could be wrong though. Thumbs Up
