In this updated how to guide, I demonstrate how to unblock the Porsche 981 Boxster S roof mechanism drains. If these are left draining poorly, they can lead to water overflowing from the hood area into the cabin, causing £thousands in repair bills and your car off the road for months! This applies to the Porsche 981 Boxster models, 2.7 Base, 3.4 S and 3.4 GTS - as used in this video.
