I'm having difficulty routing the tube that goes to the rear window washer. The problem location is at the left hinge for the rear door. I can't figure out how to route the tube and not interfere with the trim. Does it take special small diameter tubing?

Hard to say from the one picture I have, the best guidance I could really give is that all BMW washer line appears to be listed as 4.6mm, not sure on OD of course, but I do think that all of the washer fittings are the same size. Best bet might be to heat the tube (if plastic) and oval it slightly.

Will check mine this weekend and report back. I did some work on the rear washer system about 4 years ago and may have replaced the tubing.

The tubing that I am using seemed to be fine in the summertime. Now that it's cold, its a lot stiffer and doesn't bend as well.

Great. That will be a big help.

Lowe's is the problem. Do yourself a favor and replace metric with metric. It will save a lot of headaches. The OE washer hose is available from all the regular places (FCP, ECS, Pelican). Cohline also makes an aftermarket version. It's 4.5mm x 7.5mm.1992 325i Cabrio

I replaced the Lowes hose with the correct part number metric hose. It fits nicely now.
Now all I have to do is figure out where the line is plugged. The hose in the hinge is open and flows freely. The cap at the wiper is open. Somewhere in between there is a blockage.

However, if the line is kinked BEFORE the check valve, no fluid will get to the check valve or the nozzle.
I am now unkinked and completely functional.
The only problem is that I'm going through a lot of washer fluid, because it's so much fun to watch.
