    Expansion Valve

    I am in the process of doing a complete AC overhaul. I installed a new compressor, condesor and O-rings. Now I want to replace the expansion valve. Can anyone please tell me where it is located? I took off the discharge hose but I did not see the expansion valve? Is it behind the plate? Do anyone have a write up on changing the expansion valve? I do not see anything on the E53?

    Too many/Not enough
    Pretty sure it's in the dash attached to the evaporator. Likely impractical to remove and replace. Follow this link and part #2 will be your expansion valve.
