#3 of 20 2004 x3 Sunroof Problems and Leaks Please Help
Mar 01, 2008 (6:35 am)
Hello Everyone,I am new to this and I greatly appreciate your time and consideration.
I purchased my 2004 x3 with 59K miles from an auction in December 2007. I love this vehicle, drives great (gas mileage ok). I knew (or thought the rear interior shade for sunroof was missing but later noticed it was lodged in headliner) however the sun roof worked fine for several weeks. Then one weekend on a drive to FL I opened the sunroof, heard a lock of clicking (probably parts breaking) and the sunroof remained open in the "tilt" position. I took it to the local Volvo "authorized bmw center" and they recommended an upholstery shop. Took it there, they tore down the headliner removed the sunroof and said that about 400 bucks in parts were needed and 450 for labor. I like my sunroof so I agreed. TWELVE DAYS LATER , parts from Germany, they assembled and it still would not leave the tilt position when activated. They showed me in manual where "the system had to be initialized by BMW." They did refund the Labor portion of repair. I drove 107 miles one way to closest BMW Delearship authorized repair center. By the way since then it rained and I had water in rear interior of vehicle. After two days at dealership they said sunroof was "wedge" , cost would be 3300 bucks for New Sunroof Cassette, they supposedly repaired leak cleaned drains, and were suppose to program key. They could not close sunroof back and wanted to charge me 300.00 for them to close it, when it was in the close position when I brought it in!! Reluctantly they closed it back for no charge, but plenty of headache. I talked to a body shop to see if i could get a refurbished sunroof cassette, he located one for 500 but got damaged during shipping from California. Meanwhile, I noticed a couple of weeks later 5 INCHES OF WATER in the plastic "holder" in rear of vehicle and driver rear floor was also very wet. I called the dealer back, drove 107 miles ONE WAY to let them take another look. AFTER TWO DAYS, they said " when they gave the vehicle back to me the interior shades were closed and the exterior was completely shut>" They accuse me (or someone else) of opening after they closed? Why would I do that when I have learned by now that it will not be able to close back unless you remove entire Sunroof again. I CALLED THEM A BOLD FACE LIE! Obviously, I would know if this was true (the interior shades were open because it could not go into close position) they also said that my key could not be programmed because the water had damaged the TCU whatever that is. I am losing the fight because it is my word against theirs..... I would like to get my sunroof fixed It is difficult for me to believe that the entire unit needs to be replaced when something is working but "binds" when you activate motor, why not just "unbind" or fix the area that is binding. Why NEW CASSETTE? I want the problems fixed (what are your thoughts on refurbished cassettes)and the leak fixed, but do not know where to turn. Any advice would be greatly appreciated. I truly apologize for long email.
Sincerely Needs Help!!
#4 of 20 BMW moonroof problem

Lots of chatter about this. If it is the roof leaking those are likely stuffed up roof drains. People are using weed wacker line to clear them out until they run clear.
If you park outside, more like to have a problem. Someone said pollen stuffed up his drains. Why it leaks into the passenger compartment? Who the heck knows.
Other sources of BMW X3 leaking: engine compartment where debris collects under the hood catch basin causing leaking into the cabin.
Back windshield washer fluid leak.
Door vapor barriers not working.
Hopefully it is something simple like the roof drains being clogged because that sunroof is a cassette and if it breaks you may need to replace the entire thing - out of warranty?
#6 of 20 Leaking Sunroof Fix (workaround)
Aug 29, 2011 (11:51 am)
I have a 2004 X3 with 70k miles on it (although this fix will work on any leaking sunroof). I purchased this vehicle new (it was a program car). My X3 never lived outside (it had always been garaged) until I started spending extended periods of time with my fiancé two years ago (my work requires only an internet connection and an airport).
Once it lived outside, the car started leaking after every heavy rain (and when I say leaking, I mean all I needed was the koi to have a once worth $50k now worthless piece of…German engineering become an upscale pond using the floor of my vehicle). It has been in the shop numerous times since. Over the last two years, I’ve spent hundreds in having BMW blow out the panoramic sunroof drains (they eventually showed me how to do it) and hundreds more in replacing the driver’s door vapor seal. Nothing has resolved the leaking. So, I put on my closet engineer hat and came up with the following workaround. My fiance is an engineer and was impressed by the effectiveness of this workaround. (Not meaning to pat myself on the back, but desperate times leads to desperate measures.)
First, let me say that this workaround is 100% effective. It is also very inexpensive ($150.00), but it may not be All That for everyone.
What I did was find a location that installs 3M Paint Protector film, also known as the Invisible Bra. I've used the Invisible Bra product on all of my BMW’s so I had a company called Tint King install a sheet of the 3M Paint Protector film across the top of my car. (Actually, they installed two sheets with about a 1/4” overlap at the sunroof seam due to the size of the panoramic sunroof - as well as about 4" around the edge of the sunroof, totally sealing it from the elements. See pictures below.)
The film is completely see through (you would never know it was there) so you can open the shade and get full sun. You can also see out the sunroof as if you were looking through glass alone. You cannot, however, open the sunroof, which is why this workaround may not be for everyone. But, for me, that is more than acceptable.
I was lucky enough (or unlucky enough) to have tornadoes rip through the area - along with another round of torrential rains the tornadoes brought with them - the day after my install which allowed me to test my workaround. The car interior was completely dry.
I used Tint King (in London, Ontario – I am an American who spends much time in Canada, as my finace is Canadian. Tint King did a GREAT job and the car has not leaked during any of the subsequent rains, including the one that brought the tornadoes. There are Tint King locations throughout the US and Canada (I used Google). You seriously cannot tell the film is on the top of the car. It is crystal clear. (The film is also 100% removable should you desire to remove it at a future date.)
Sorry for the reflection of the car's interior. I snapped these with my cell phone right after installation and there's not much to see other than gray and blue sky.
Note that the remaining water from the installation has completely dissipated and the film is flat and perfectly installed. They couldn't initially squeegee out that bit of water due to the lip around the sunroof.
An Unconcerned BMW of North America:
When I called BMW of North America to ask them to help me out with drying the underside of the mats (IOW pay the labor to pull up the mats and dry the vehicle once and for all), they told me tough luck. I need to eat my German engineered crap sandwich and enjoy it. The cost for BMW to dry out the flooring under the mats is more than $600 which is all labor.
I was told that BMW is completely unaware of any leakage problem in their vehicles and it was my responsibility alone if I wanted to dry out the cabin floor. I tried to get some pages of a manual to show how to pull up the carpets so I could do it myself and was told to check YouTube (I couldn’t find one that applied…if anyone has some help/instructions for pulling up the front cabin carpeting it would be greatly appreciated.) I was told that there were no design problems causing leakage and too bad for me.
I told her I was a three time BMW owner (new 2001 X5, new 2004 X3, used 1999 318ti) and was looking to get a new car in the upcoming months and that I had a hard time justifying buying another BMW when I didn’t feel that they were standing behind their product in what is obviously, reading all the BMW boards, a design flaw. Enjoy my turd sandwich was the only response.
A couple of other things; the installed carpets show no sign of mold (something I won’t know fully until I can lift those carpets up). The BMW floor mats molded badly. Once I removed them, the smell immediately went away. I will not be replacing the BMW mats. I am going to solely replace my ancient WeatherTech rubber mats.
As an added bonus, the cabin is much quieter now that the 3M Paint Protector film is across the top of my car. It used to have more wind noise than I would like with the shade fully open. No more.
Lastly, my vehicle is older (though I am the only owner) so I probably have little leg to stand on in a class lawsuit, but I think that owner’s experiencing this disaster with their once worth tens of thousands of dollars but now worthless pieces of…German engineering should band together to get some kind of compensation. Seriously, who is going to purchase my or your leaking BMW disaster? In my eyes, this is unacceptable for a premium brand.
Now that I no longer have the leaks, I will keep this guy until it’s time for me to get a new car and then I will probably give it away to one of my friend’s kids or donate it to a good cause.
Sorry for the length of this post.

Justjayna, Thanks for your post. Hopefully this information will be helpful for my garage and may be worth a trip to Quebec or another company that tints as you state.

I've had the same problem with water leaking into the rear passenger floorboards of my 2004 BMW X3 over the last several years following a heavy rain/snow.
BMW of Arlington did attempt to repair the problem (replaced drains and interior carpeting and floor mats) and they even covered 100% of the costs (several thousand dollars) but the problem resumed within two month's time and has gradually gotten worse over the last two years. The moisture has created a mold and mildew problem (again) and I am worried about the potential health consequences of being exposed to this for prolonged periods of time. BMW was never able to identify the source of the leak and they tried several high-pressured water tests to no avail. But, it's clear to me that BMW will not be able to correctly fix the problem unless they do something akin to the solution that you've proposed.
One thing that I have recently noted is that there is a container in the rear (just inside the hatchback) on the right side of the car. This container seems to fill with water after it rains and the floorboard seems to be dry until this compartment becomes full. Has anyone else noticed this?
In good conscious, I can't trade this car in and pass this problem along to someone else. I bought this car used from Carmax and I feel that someone else just passed the problem along to me. I also plan to give the car to a friend or donate it once I'm ready for a new vehicle though I'm worried that the mold and mildew could create health issues with the next owner. Obviously, being unable to trade the vehicle in represents a loss of thousands of dollars to me and I would support a class action lawsuit. It sounds as if BMW has been made aware of this and has not taken the problem seriously, at best.

How is the 3M paint protection film holding up? I have a leaky sunroof on my 2004 X3 and am considering your innovative solution. I certainly don't want to spend the $3500 or so I understand it costs to fix the sunroof, which will probably just start leaking again! Thanks in advance for the update on your car!
