convertible roof leak

Hi Guys, first post here though i've been around lurking for a couple of months.

i got a 420 convertible back in August and this week had a major roof leak...passenger side rear footwell was very wet and i could hear water splashing around under the back window near the rear speaker.

its back with BMW now but i wondered if anybody knew of this problem happening before that could point me in the direction of what to double check with i worry they will simply not recreate the downpour we had at the weekend and just lube up the seals and tell me its ok.....which is fine until we get another downpour.

Take pictures as proof of the leak and ask bring it into your dealership to see if they can replace the roof. It shouldn't be leaking at all and the ca should still be under warranty if you bought it in August.

I used to work in a dealership and remember they did a smoke test once to see where the leak is. If you have a humidifier, having it run inside the car when you feel the need to do so can help in detecting them.

Surprising that it would be leaking when the car is so new. Dealer will fix it I'm sure but the humidifier test sounds pretty fun to do yourself.

I have exactly the same problem. Took the car to BMW yesterday and they say there are drainage holes under the car that are blocked and want to charge me for the repair!!! Seems like they know there is a leak and instead of fixing it put in a poor workaround. Did your garage resolve it?

Bring your car to the dealership and have Roof Repair , this can prevent the leakage of the roof.
