Water leak inside car!

I have a 1994 325i (E36) 4-door. When it rains, I get a LOT of water into the passenger's side floor. Enough to form a small puddle. Happens even if the car is parked (motionless). No obvious issue seen around the door perimeter with the seal. Has happened repeatedly, with every rain. I do have a sunroof, but no apparent issue seen there.

What is likely source of the rainwater entry? Is this a known issue on the E36?

Thanks much!

It's coming from your sunroof. There are two drain tubes in your sunroof track that have hoses that run through your A-pillars through the footwell and glove box are and eventually out the bottom of your car. Your hose is most likely disconnected somewhere and you will need to find where.
I recently did this on my e36. How I found it was by opening my sunroof and slowly pouring water through the whichever side is leaking, mine was also the passenger side. After looking closely I thought I was leaking from somewhere behind or the the right of the glove box so I removed that which showed me the water was leaking from the A-pillar. So I removed the carpet from the A-pillar, the hose is behind a metal frame and you can't see much but thankfully that's not where my leak was. Next was the headliner, removed that and the hose was in plain sight and clearly disconnected, in the are of where the passenger "oh ****" handle is. I reconnected the hose and added a fastener and haven't had the problem since. It's really just following the hose and finding where it's broken or disconnected.
I almost certain this is your problem as I've had the same symptoms and have read that it's fairly common on alot of BMWs not only e36. I hope this helps and I will try to see if I have any photos from when I did it.

Pretty sure Minne hit the nail on the head. Also another common problem you could check is either damage or clogged drain tube. You should be able to find the end of the drain tube somewhere along the bottom of the A-pillar or under the car. I can't remember if these tubes drop out of the bottom of the car or through the inner rocker panels. None the less if you can find the end, you may find the tube is either clogged itself with leaves and what not or where the tube drains is filled with debris. Let us know how it goes!

If not the sunroof drains, check the cowl area drains. Thatís another common area to get clogged on the E36. If itís a significant clog, water backs up into the DME compartment, shorts it out, and you have a dead car.

I believe they drain out of where you would jack your car up at. There are holes at each of the front jack points.
