Drainpipe from the panorama sunroof DIY E70

[edennelson]

The drain runs from your roof down to the in bottom of the car.
Remember this is simply a plastic tube so don't be too rough with it.
If you get overly aggressive you could puncher the tube and cause a leak in your cabin.

I pour a bit of water into the gutter, while I work. As soon as the clog is gone you will know because the water drains.

I had time to check today and able to locate the front sunroof drain. The rear however is not easily accessible. I have the Panoramic roof and the second glass does not retract all the way back to review the drain hole. The passenger Rear is where the water is leaking into the vehicle. Then I tried to tilt it upward, it only allowed for a few more inches but still do not review the drain. Can some advise or has unclogging the rear drain never been done outside of the dealers?!

I think you will need to attack the drains from the bottom of the car.
I will see if I can locate the rear drain outlet and take a picture.

Is the best diy we have for the clearing the drains of the pano roof? I ask because I have a "tiny" collection of water after big rains between the left rear door and the body. When I open it I get a little puddle that drains out. Was wondering if its a clog.

...and didn't mind it too much until my bro-in-laws car needed 2k$ worth of electronics replaced (2011 535 wagon) today due to pool of water from clog in battery and module area. Ouch.)

Thanks,

I had problems with mine too, I got water damage so bad, I filled up the Compartment in the trunk where the electronics where located, it messed up my GPS, Satellite Radio, Radio, Wipers and Signal where not working. My car just finished getting out of warranty 2 months before, and I ended up paying $5000.00 to get it replaced. This should be on a recall and fixed for free for any BMW.

why didn't you claim it with insurance? It is water damage

This is an older thread, but I thought the relevant SIB would be of value. This was originally published in 2008, but has been updated several times - this version being from Aug 2013. See below.

I was just sent an email notifying me that this thread had activity. I forgot to come back after my post above and relate my story from last May (2015).

I had a little water collect in the "cassette" after a sturdy rain. Shortly thereafter got funny dash lights, lot's of stuff "inoperable" etc. Got home and noticed that all brake lights including third brake light remained on even though car was off! Now really worried so got in car and turned ignition on and off, still problems and then I smelled smoke! Some sort of fire started in the passenger B-pillar near the floor. Burned through the pillar onto the carpet, curtain airbag went off and that's when I panicked and called 911. Pretty bad fire, car was totaled by insurance.

Such a bummer, I loved that car. Cost me a lot to get a newer one, I settled for the 3.5 instead of the 4.8 and still miss the growl and take off of the V8.

Definitely check your sunroof drains, watching your car burn in your driveway is terrifying. It's totally unmovable by the way, if it was in garage I would have lost my house!

I cleaned out the rubber boot under the car where the drain tubes exit. It gets clogged up from road debris. And I used lawn trimmer cord to fish down through the tube as someone else suggested. Then I flushed it with water and compressed air. No more leaks!

If it's the rears, my E53 exits into the rear hatch. Open the liftgate and fish up into the sunroof with it open and then blow the compressed air through
