325i: Where is the water coming from?

It could be coming in from the rear, from the boot area. Or you could have sills full of water due to blocked drain holes, these would overflow into the car eventually. Seen both before.

Windshield bottom seal, along the hood, my son 325is 94 had same problem after 3 hours rainstorm. Water gets to the AC blower housing and into the floor, the back is the lower point, your front mats should be wet too, but not as bad as the ones in the back.

Hello,

Well in my 635, the front sunroof drain tubes were made of some type of material that shrunk over the years and retracted inside the frame of the car. So instead now the drains were filling up my rocker panels and inside of the cabin as well. Can you locate the drain tubes and verify how they are routed?

Oh and yeah, the front windscreen leaks are sooo common.

I will investigate the drain tubes. The sunroof was serviced a few months ago, perhaps the drain tubes were knocked out of position.

I have not considered the windshield because the front carpet is dry but the rear carpet is equally wet on both sides.

Thanks for the ideas.

I have found on several types of BM,s water coming in around boot seal.

check the door vapor barriers real well against door frame,if they are not sealed properly, water will leak inside vehicle. if you have had a window regulator replaced or body work done on a door. start there...good luck

I'd first check for a blocked sunroof drain.
