I have seen a YouTube vid that showed that very thing.

I just watched this and wondered why you need the drain plug at all... Is it to keep spiders out?

Managed to find a simple way of cleaning both sump drains. It is much easier if you do this with the wheel off but not necessary.

1. Drop the hood and shine your torch down the hood frame assembly, you should be able to see water if there is a blockage.

2. Thread about 500mm of rubber hose down between the hood mechanism into the sump area and blow down hose. You should hear the water bubbling, this will also dislodge some of the dirt from the top drain point of the sump.
3. Remove tyre and small arch panel.

4. Now attach your electric tyre pump to one end of your rubber hose and thread the other end up through lower drain point as high as you can into sump area.

Activate your pump and you will hear the trapped water bubbling away in the drain sump. Do this two or three times and retract rubber hose, you should now see water running freely out of your drain. Job done :thumbsup:

Hope this helps you guys.

I spoke to my local bmw specialist and they claimed that the roof needs to come off (5hrs labour) to carry out a full drainage check? Apart from the lower plugs are there top drainage areas to potentially clean out....or is this garage misleading me?

After long reading about this subject, along with the roof motor relocation inside the trunk, I can tell you that your BMW specialist is right.
Top drainage area (one in each side of the car) has a very tiny hole and dirt blocks it very easily.
The biggest issue is that one of the drainage areas (passenger side in UK) holds the roof motor and when that area is clogged, it gets flooded and destroys the roof engine.

You have a lot of info about these issues not only here in the forum, but in the web.

Get the roof motor relocated to the boot where it won't get wet again, plenty on here about this job.
Don't pay the garage 5 hours labour to remove the roof, that's just madness :roll:

My roof motor has been relocated, but is now wet as I think the drains have over flowed due to being so blocked and have made the boot wet on both sides!

Today's task is so fix this!
