  • Air con drier

    My A/C is leaking again so need to get it checked out but was thinking that the drier has never been replaced so a good time to change or do people not bother with it being such a expensive (genuine £170.) part?

    You probably know already that leaks are 99% of the time related to the condensor/radiator, but the drier I'm not sure if it's worth changing at the same time as it's being done if it's still working ok?

      I always replace the dryer cartridge if there is any chance a leak had introduced humidity or water into the system. The AC system requires essentially 0% humidity internally to function properly and that's what the dryer is there for.

        Because of the climate here I take AC very seriously, It's pretty much essential 6 months of the year. I'd start with a little tracer dye to find the leak and then fix it. Then I'd sacrifice the freon that's in the system, replace the dryer, and do a full vacuum pump down and leak check. Then I'd refill with exactly the amount of freon shown on the label in the engine compartment. This has always worked better for me than trying to judge the fill based on high side/low side pressure vs. ambient. Even when working perfectly I would only rate the M Coupe A/C as adequate, it's not really desigined for hot climates.

          I had a new condenser fitted so the leak is from one of seals on the pipework, I will get the drier changed as this is the third leak I have had and it may be past its best.
