Checking Boxster Drainage Holes

There are two drainage holes in the space where the roof retracts to. When up the water from the roof will run down into this area, and in theory down the holes and out the bottom of the car. If these holes get blocked up the water backs up and enters the cabin. The first place it heads is under the seats where the cars brains are. So its a good idea to check these and the two holes in the front by the battery.

Open the roof into 'service' mode. Which means just open it 30cm which causes the rear cover to open. The holes are in each corner, check they are clear and pour some water down to confirm.

There are also two holes for the front, each side of the battery. Looking at the car the left hand hole is pretty easy to spot and there's what looks like a mirror on the right, its not, that's some kind of grommet.  The actual hole is about another 5-6 cm to the right.
