Ok opened the wheel well and the drain was choked with sludge and mud...cleaned it out. Next I poured water along the sun roof pipes....and sure enough the driver side(In my case Right hand side) the water was not coming out of the drain in the wheel well....Pulled out the carpet and found the pipe....near the firewall it turns and exits out and then drains in the footwell drain.pulled it out and no water was coming out of it....cleaned it with air and sure enough sludge came out...flushed it completely and put everything back....now waiting for another spell of rain.

so the pipe goes through the firewall, did you mean it goes into the cowl area under the windscreen, not the foot well?

I'd not use compressed air as you will (very likely) end up blowing the rubber hose from the connections. Better bet is to take some week wacker thread and run it from top to bottom to clear them. Pouring a bit of water as you do so to loosen up the debris.

On some P!G forum or another - I posted a comprehensive photo show of how the passenger's side leak starts, the path it takes and how to fix it. I imagine the drivers side is the same.
What is likely plugged up is the drain up where the sunroof seats. It is in the lowest corner of the plastic under the sunroof - up under the roof of the vehicle. It is near to impossible to see, but you can clean it out with an airgun. If you pull off the A pillar trim (as is shown in the photo above) you may find a trail of drips that flows right down the inside of the trim, down past the fusebox, and down behind the kickpanel to under the carpeting - where it soaks the 2" of foam rubber that is under the carpet.
To access the plugged drain, you must first remove the A pillar trim, then remove the sunvisor mounting, and pull down the headliner in that corner of the "ceiling". If you then shine a light up into the area revealed you'll see a rubber tube going to a nipple on the back side of the plastic that is under the sunroof. That's the drain. With the sunroof open, and towels covering everything in the area - you can remove the hose from the nipple, and use compressed air to blow the drain clear.
Chances are - that will fix the problem. Pollen and leaves like to get into that drain and plug it up. Once it's plugged up the water overflows the edge of the plastic tray like thing, and then follows the path I described above down to the floor area. It's actually fairly unlikely that the bottom of the hose is plugged up, but I guess it can't hurt to check.
The test I used was - after hooking the hose back up - I poured a pitcher of water into the plastic tray thingie - and it drained out on the ground with none spilling over into the interior of the car. No leaks since, but it's probably time to clean the drains out again, we had a LOT of pollen in NJ this year.

I have a pillar airbag it's behind the pipe....could see it, white in color....my friend got in the car and stood up into the sunroof....he then put in a small pipe connected to a water supply..he didn't pull the roofliner down....the pipe went into the hole and filled with water...but nothing came out from below.....so the lower end he cleaned with a air gun and a zip tie!!
So this pipe turns and goes into the box where the ECU is and then from there drains into to footwell drain

Inquiring minds want to know..
BTW - if you open the link I posted and look at the photos you can clearly see the routing of the sunroof drain down the A-pillar and the location of the A-pillar airbags (which are toward the interior side of the A-pillar.)
Perhaps this link might work - the A-pillar. The airbag is the white tubular thing, the drain is the rubber house highlighted with the green line:

Ok so what my friend did was got out through the sun roof and put in a small pipe connected to a water source (a bucket) and flush it with water...after sometime the water overflowed and so he stopped...I was at the lower end and had followed the pipe between the brake and accelerator....in the firewall it makes a 90 degree
And has a nipple and a sharp tip....I pulled it out and milked it but only thick muddy sludge would come out...and there was no free flow...so we inserted a zip tie and opened up the tip and also put pressure from the top with a air compressor...and suddenly water just poured out...I reconnected the drain to the firewall and put water again and water came out of the footwell and was clear water....
To clarify in the footwell u need to jack the car up, remove the tire and open the wheel well lining(tons of screws) and water was coming outta the footwell drain

Another interesting thing I noticed is my driver side leaks which is right side and your passenger side leaks which is again right side...so basically only the right side gets blocked???
Kinda weird
