Job took me 1 and a half hours to do the job. Ridiculous how many clips there are holding the door card on. Whenever I take it off, and put it back on, I always find 1 clip on the ground. Don't worry, window reg will eventually fail and then I can put the spare one back in. And then another one will fall out. It is a like a vicious cycle.
Well there is your problem. Awesome that it failed during Bimmerfest.
Just ordered the PS res and going to replace the fluid and res for the Power steering.
