If you did not get it to clear out from above I suggest you go back and try some more. I think to clear the bottom you have to take part of the fender apart on an X5 for access. I would work a long time from the sunroof to get the drains cleared. Warm soapy water helped clear mine. Ran the soapy water in till it backed up and then hit it with Air Pressure using my compressor and I have a small air tool to blast a small stream of air down the hole. My device allows me to turn it open and let small amounts of air pressure in at a time, this allows a little pressure to help the soapy water work.
I probably never had more than 15 psi in the tube at one time until it cleared. Then I ran more soapy water in and hit it with full pressure from my 150 PSI source.
If you hit it with too much air first I think the tubes in your car may burst or separate leaving you in deep SH**.
