    PS Reservoir Filter Replacements

    I'm wondering what filter needs to be replaced in the power steering reservoir...the diagram from realoem seems to show two different filters, but when I pulled mine, it only has one cartridge style filter (#1 in the diagram) in there. Am I missing the second filter labeled #3 in the realoem diagram?

    Hmm the couple of times I have rebuilt power steering systems on these type of cars I opened them up and only found the #3 style filter in the reservoir.

    Have you done any early, pre-'82 cars? Mine is a weird, early build '82 that is essentially an '81. Has all the early E23 stuff. But yeah, there was definitely only a metal cartridge style filter on mine. I'm wondering if it's possible that the smaller, #3 style filter disintegrated or was left out by some uninformed PO.

    No, I have not done anything that early. My experience is with late model E28's, although I am planning on overhauling my '84 733i power steering system at some point this spring.

    Ahh, gotcha. I need to take another look in the reservoir and see what's going on...if that diagram is correct, I'm missing a few other pieces aside from that bottom, sinter filter.

    That bottom filter was indeed in there...looks original, completely misshapen, and clogged. Now I need to find the sinter filter (32411120715) and the metal, cartridge style filter (32411123323)

    Hopefully I'm able to figure out the correct parts. Might have to give a call to FCP Euro or some place like that as opposed to ordering on Ebay.

    Send an email to Steve at Blunttech, he has been very helpful with finding parts for me over the last several years
