Anybody know if there's a chart or some sort of map showing where all the drainage holes are for the car?

 

I was cleaning the plenum chamber and noticed it was filled with leaves and dirt, makes me wonder if there are other drainage holes blocked that need to cleared. The official service repair manual has a chapter named "Manual for locating water entries" but it doesn't really show specific locations for drainage holes throughout the car, it just gives some examples and guidance on how to find water ingress.

 

My car doesn't have a sunroof but I did notice a water drain pipe right behind the back bumper on the right side, maybe it's a drain for the fuel filler cap cavity?

Yes that's what that is. Apart from the scuttle drains there are obviously drain holes in the bottom of the doors but not much else to worry about really.

 

There are some in the box sections on the underside that drain the areas either side under the brake servo and opposite under ECU, but not a threat to interior dryness even if all blocked up.
