He's at 70k, but I'm at 23k with the same issue. I just checked and looks like there is a filter or strainer integrated into the hpfp, so not serviceable. I changed spark plugs last year with OEM so will assume those are still good. I ordered OEM Delphi coilpacks as something to try, I ran across a few posts from other threads where guys shotgunned coils and plugs and fixed the issue. Given BMW history with coilpacks it's not a bad idea to try ($166 on rockauto for 6). I'll report back when I put those in, worst case I have spare coils
