Front passenger side wet floor

[lowrider_rt2000]

Hello everyone. Newbie to the forum. I've owned my 05 9-3 for a few years now and love it! Lately I've been having issues when it rains. A good downpour and there's a big puddle on the floor. I have tried everything to figure this out and I'm at a total loss! Here's what I have done so far,
1. Checked for clogged drain holes in sunroof.
2. Poured water down drain holes and water exits onto driveway like it should
3. Checked under wipers to make sure the drain isn't clogged.
4. Took garden hose and ran water all over windshield.
5. Took garden hose and ran water over passenger side door while door was open. Water drains out of door like it should.
6. Took garden hose and ran water over passenger side door while shut. No water leaked inside car.
7. Ran water over the whole car and not a drop came inside.
Is there anywhere else I can check or does anyone else have any ides that I might be missing? Any info would be greatly appreciated! Sorry my picture wouldn't upload.

I guess you are missing the Guard plate (water barrier panel), Saan part number 12765989 (LHD Cars only. P/n 12765990 for all those people driving on the wrong side of the road ): https://www.eeuroparts.com/Parts/641...anel-12765989/

Put the wipers in the service position (not performed on below picture):
1. Turn ON the ignition switch
2. Turn the ignition key to LOCK
3. Move the windscreen wiper lever downwards until the wipers are in the upright vertical position.

Then open the bonnet, remove the right hand side plugs, loosen the rear main seal (on the bulkhead) halfway and fold up the cover to reach the guard plate.

Hmmmm...I definitely do not have that piece there. But why only now start to leak?
