Instead of doing this just make sure that you clean your drain holes every year and you will never get roof motor or amplifier issues. I do this with my 2003 Z4 and it's totally perfect.
I don’t know if it’s something that’s not well known in the US, but in the U.K. we tend to move the roof motor to the boot which stops the bottleneck by the drain holes. Saves the motor and your amp and it takes about an hour if you’ve got the right technique. Took me ages longer, but I was shit at it!
I was unlucky enough where the clogging u mentioned caused the motor operating the rooftop to rust. Cost me $1200 to get a new one installed, and they drilled holes to avoid reflooding. Been meaning to write to BMW and ask for some sort of compensation, or hv their engineer fired!! Seems like a flaw in the design to me!! It’s barely been used and kept in a garage, not sure how it would get clogged so easily. 😠
Does not take much, one day in the rain, and the motor will sit enflooded for a week. Once it dries up, everything would be rusted. The drain holes are about 1/2" in size. All it takes is a single leaf to sit over it. You wownt get any compensation, unless there was 10000 people with a class action suit, and even then, its a waste of time.
Very helpful, thank you. I jus got water exactly how you described snd I'm having trouble with the mid ranges and tweets and lots of noise. I'm taking it out and getting it cleaned with alcohol and pressurized air. Wish me luck.
Parked on a flat surface, with no structural damage, or clogged drains, yes Parked nose up, especially on a steep hill, 100% will fill your trunk Clogged draings, will also fill fhe trunk
The exhaust pipe does not face under the battery, it comes out the rear of the car You breathe more gas fumes sitting in traffic than this could ever cause
Unfortunately your comparisons are useless The trunk does not leak, the trunk fills up with water due to an engineering flaw, and noone is going to pay 1500$ every 6 months to properly remove the top, and clean the drains
I would bet 90% of z4 owners have never cleaned, or even heard of cleaning these drains Even if you do "clean it" from below, i would bet it would just re-clog after a week, its impossible to get everything out unless the roof is removed, i would know, ive done it
@@MaksimIzer I would bet 90% of viewers would see the error in your video. That's the actions of someone who doesn't care and has given up. And then to post a video on YT like you've discovered the miracle cure for it, smh.
I Replaced the amp Today but only one speak sound very low and static / cracking noise. Any ideas what it could be? Or the speakers got damaged since the previous amp was soaked in water Please help
Its possible that you damaged the speakers, but unlikely all of them. If you bought a used amp, it might be faulty. The only way to test, is to test each speaker individually, then hook up entire system. Easiest solution is to borrow a working Z4 amp.
