E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Floor Drain Plugs

Hi,

I found a ton of water under the driver's side carpet this weekend, and have managed to sop most of it up with some towels. I've read many reviews that talk about all the possible causes, but then I actually found that one (at least, have to check the others) of my drain plugs is missing. I recently took it too a car wash and sprayed underneath with a high-pressure sprayer, so I'm hoping that is where the water came from and it's not a leak of sorts. There doesn't seem to be any water coming down from the firewall/doors/etc. Sunroof drains seem to be working OK, except maybe the right-rear, but that would drain to the back of the car anyway (left rear drains out behind left rear wheel).

Anyway, the drain plug that's missing is one of the smaller ones that is furthest up to the front of the car. It's basically on the floor below the brake pedal. There are larger holes that take the metal twist-on covers... that's not the ones. I can find on "RealOEM", the following link: http://realoem.com/bmw/showparts.do?...44&hg=51&fg=80 ...shows several plugs. #5 are the metal ones I'm talking about... but I don't know which of the others is the proper plug. By memory, the hole seemed to be less than 2", which would be about 35mm... but none of the 35mm plugs look right based on pictures I've seen. The #18 looks right, but it shows two sizes of 52mm and 12mm, and they seem too big/too small respectively. Anyway, if anyone knows where I can find those plugs, that would be much appreciated! Here's a couple of pictures (not one, and one's a right-hand drive example) of the plugs/holes I'm talking about.

Here I would go past a panelbeater as they stock a variety of plugs
Or the Auto Electricians that do trucks...

As an FYI... I've found the right part number. The smaller holes in the floor boards (shown in the picture) are fitted with BMW part # 41007140847. The old part number is 41121907234, but that part is shown on RealOEM as "ended". I got a bag of 5 of these plugs from my local BMW dealer for $7 and change (CAD), taxes in... doesn't hurt to have a few kicking around. I might even buy more!

Mein Auto:
fast forward to 2020, the lowest cost i could get 1 shipped to me from offline was 1.69 for the part and 5.54 for shipping from fcpeuro.

Alternatively i found i can buy a lot more 1.375" locking panel plugs for less cost. I will add some sealant and underbody spray to make it water resistant. here is an example

The bmw part description reads "Paint plugs with hot-melt adhesive ring" so if i had an unused factory plug i would heat it with a heat gun.
