Drivers side is tight and I was worried about unplugging the frm module because bmw makes them out of glass and they die from less... It was a tight fit and I had to rotate it from the outside and verify it was un kinked from the inside.

Did you remove the passenger side and was the pipe exit visible? Maybe I'll have to pour soap or something non corrosive to prevent future issues.

Air pressure didn't help my drivers side and actually blew apart a coupling near the a pillar... I was so mad, but luckily I was able to drop headliner there and reconnect it.
