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!

Did you report this to the NSTB? if not, could you??

Thanks

This is a BMW defect that was covered by insurnace, if this was under warranty BMW should be liable...

...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.)

I also have the same problems, pooling water by the running boards of both rear doors. Door seals get wet sometimes. Happens during car washes and heavy rains.

Does anyone think this could be from sunroof drains?

Your door vapor seals are leaking. Pull the panels and reseal. I had this problem if the water is on the bottom of the door seals

I also got water in my trunk in the bucket under the amp. I'm trying to find the pano sunroof drain holes.. no luck. Especially in the back where the glass is covering. Does anyone have pics of the holes from the top and bottom of the car?

Thanks,
Tommy

I don't see the year of your E70, but for my 09, the outlets for the back drains are visible when you lift the tailgate. Look at the top about 6-8 inches (guessing distance) from each side. The outlets have little flaps covering them.
Sorry, I do not have pics.

I have an 09 as well - I'll check it out tomorrow- thanks!

Did you also have a problem with water leaking into the left boot?

[tgunz83]

I found the drain holes, thank you. They had some dirt in them but water seems to be draining fine. Also, since the tube doesn't run through the trunk area is it even possible clogged drains would cause water in the boot?

I know another possibility is the tail light seals leaking.. i posted on a separate thread about that. Looking at the tail lights though I don't really get how water from the tail light could get in the boot

Not really sure how to figure out where the water is coming from other then doing a garden hose test I guess.

Yes, they can. If the drains are clogged water backs up in the cassette and then spills over onto the headliner and runs down the C or D pillars. Yes, your tail light assembly can leak into the boot also.

So, I just found this thread...Im running in the same issue, sunroof drain tubes clogged, bunch of electronics toasted, looking at a total of 5 plus k repairs at the BMW dealership.

BMW of NA just denied my warranty claim because those are items running under maintenance and were caused by "external factors". The Service Advisor told me because the car was "parked under a tree" and the drainage got filled from debris from the tree.

I never seen in the BMW cars manual do not park under a tree nor a schedule maintenance for the drain tubes.

The car is a 2011 35d. The car was serviced all the time at the dealer. It also had the maintenance plan from BMW. - expired at this time.

I'm debating what to do next...
