    Replacing evaporator and expansion valve -92 850i

    Hi all,

    I am trying to replacing my leaking expansion valve and seriously dirty evaporator as well. So far I have not been able to get the parts out and I have been following the "Repair Handbook" to the point and removed all the mentioned bolts, nuts and screws but the tubes and parts are stuck. Both the nut and the associated bolt (red circle) is removed but today I found the the 2 torx screws (yellow circle) also shall be removed. These 2 screws are not mentioned anywhere as I have found in the literature.

    The tubes are usually stuck. They have oring seals that can be a little stubborn to separate.

    Envious of you LHD guys, so much easier.
    I fear I may need to do mine as I had a fluorescent fluid leak above the transmission tunnel and when I turn on the AC, the air smells like refrigerant. But it still feels cold, and when I changed the clutch and flywheel my mechanic said there did not appear to be any leaks... so I will just leave it for now.
    I need to take the whole steering column out to get to it...

    Someone on here has a write up where they take it out through the console. Someone will know where it is.

    It is old, 2010 but covers my problems accurately. Thank you, Shogun.
