  • Air Conditioning 'O' Rings.

    My Aircon was working fine when I got the car, but after a while I noticed green slime (A/C lubricant) emerging from the hose connections at the bulkhead, followed by a drop in performance. I looked up the 'O' Rings on RealOEM: http://www.realoem.com/bmw/showparts...17&hg=64&fg=60

    Now, I would have said that the parts that I required are items 9 & 10, but the picture of the hoses doesn't look quite right so I thought I'd leave it to BMW to decide, so I gave them a call. Today I got our neighbouring workshop to de-gas the system & took the hoses of only to find that the parts supplied were nothing like, although it does appear that someone has been there before!!

    One of the 'O' Rings looks like its an ordinary one as it's black, the other is purple, but both are much fatter i.e. the new ones are too thin!

    Spoke to BMW again & they faxed me the picture from their system which is the same as the one on RealOEM. Apparently he supplied items 6 & 7, but item 7 is the same as 9 anyway, just to be awkward neither BMW's system or RealOEM give a part number for item 10!

    Have any of you had any dealings with this before or can any RealOEM expert find another picture!!??

    If I can't find the right parts I'm going to have to look for a kit of generic A/C seals (my neighbour had some, but nothing suitable)

    Martin..

    I had this messing about when i did my AC....

    All supplied O rings were about 1/3 diameter of the OEM ones in the system.

    I may have some spares in a packet at work....

    I will check..

      Cheers Gary,

      I've found some assortment kits on ebay or might try Wurth if you haven't got any!

        The rings supplied by BMW are 1.6mm thick, both of those that were removed are 2.4mm thick. Wurth do a BMW/Porsche kit which contains 'O' rings which are the right size and are 2.62mm thick, maybe this is what's required to stop the slight seep that was present!

        I'll have a propper measure up of the pipes & fitting tomorrow.

          Ordered a generic kit containing 30 different sizes today, so hopefully there'll be the right sizes in there, the rest will save us loads of time looking up the right part numbers for Land Rover ones!

            Rings arrived, chose suitable ones & fitted them, had the system charged; no leaks, all OK!
