I can tell this is bugging you isn't it!

LOL, I just found out about them, after reading this thread.

The hunt is on!

The knowledge is nonexistant?

My understanding of these drains is that they are more significant for the cabriolet owners--particularly those that drain the areas adjacent to the rear side glass.

The front drains which clear out the area aft of the trunk which contains the battery shouldn't to be ignored, either, however. There are cases where a 996 owner didn't stay on top of those drains and the rain water accumulated enough to flood his brake system and even got into the engine (because of that) ultimately totaling the car.

This is largely a problem for people who park under trees because it's the leaves that lead to blockage.

They're very easy to see, just remove the guards on each side of the battery and you'll see 'em.

That's right Dan….I had a couple of huge trees next to my driveway and the tech always had to clean the drains and the leaves would invariably wind up in them.

Sunroof drains are easy.. Use some weed whacker line it them. There are four. The fronts can be seen, they drain to the side. When you push the line in it will only go so far as there is a 90 degree turn where the drain into the top of the wheel well behind the liner. So the tube runs down the a pillar then for may be only another 6 to 8 inches where it terminates. The only way to run a line all the way is to pull the liner and go up the bungy But you don't have to do this.

The rear drains go straight back but I don't remember where they drain.

These are real easy to work with a whacker line.

A big ++ for the battery drains.... Mine were clogged with disgusting leafy organic matter and I ha a pool of water sloshing in there. Just jam you fingers into the holes to clean them...they have a rubber flappy thing that cloggs.

After clearing all holes, pour water and see if they backup. The front roof drains are stupid as the water drains all over an electronic sensor in the wheel well...I think it is the tpms pickup but not real sure.

Wonder how difficult it is to get a string through that back drain of the sunroof? What do the dealers actually use to clear these up? Thanks Tim for the diagram

HELP!

So I thought I would be helpful and post some pictures of the drains in the front as I found them poking around trying to get water out of the battery area after I washed the car.

I was making sure one of the rubber gaskets / plugs was clear of debris and inadvertently pushed it completely through the hole...see attached picture. I had hoped it would have dropped down under the car...no such luck. Do I need to worry about it and if so, how do I find it? I assume I will need to take the wheel off and then remove the wheel well liner.

thanks

Sorry for bumping an old thread...

I've just done exactly the same as David above, except on the other side of the battery. Car is a 996.1.

Went to unblock the drain on the right hand side of the batter (as you face it, RHD car) and mistakenly pushed the piece of rubber too hard, it fell through the hole. Tried to retrieve it with needle nose pliers but no joy... it eventually disconnected itself from the tube that it's attached to (which I believe runs to a hole in the wheel arch) and is nowhere to be seen now.

Even if I am able to retrieve the rubber grommet/bung, any idea how I can get it reconnected to the tube/hose?
