Just got back from a visit under my car. I tried to locate the drain plugs, but I am not sure if I found them...?

For those interested, I have uploaded a few pictures on my site. The first one http://www.homeofsbc.com/picture1.jpg display two simple holes. The picture was taken by using a mirror, since the lowered car doesn't leave much space for a camera.

http://www.homeofsbc.com/picture2.jpg looks more like a drain outlet to me. I found something like 5 of these from the front to the rear wheel, but they were all closed. Scratching on the inside made a metallic shine, so I guess this isn't the drain plugs after all.

Burried on the the passenger footwell carpet I found these plugs http://www.homeofsbc.com/picture3.jpg, but they seem to be completely sealed?

While I was at it, I also took a look inside the engine bay, trying to find the AC outlet hose and to see if the ebox connection through the firewall was leaking. My model has no connection from the ebox, though, and there wasn't any room whatsoever to check for the AC drain.

So all in all, I feel like a complete jackass, not being able to find/do anything. Unless someone here is able to help during the weekend, I guess I'll be visiting BMW on Monday... :-(
