Windows and sunroof open by themselves!

Well, having just got the car back from the dealer Thursday night after long crank episodes, Friday morning all the windows and the sunroof were wide open when we went to get in the car!

Fortunately, we have a garage, so it wasn't a security problem, and even though it was raining, everything didn't get soaked. But, still...

This morning, they were all open again! Back to the dealer.

He speculates the remote in my wife's purse somehow gets crimped and the open button held down, which with Comfort Access will do what I described. She thinks it unlikely...the dealer is going to check it out, and we asked them to disable that feature of CA, in case that is what's going on. I'll note we've had the car since September and it never did this before. You know the old saying -- "Once, is chance, twice MIGHT be coincidence, but three times is enemy action!".

We were not particularly thrilled by this one, as you might imagine.

I was going to say it seems like a malfunction with the unlock button getting held down somehow. Other than that, I'm not too sure. Fuse? Some sort of computer malfunction?

This is not specific to CA - any remote will open the sunroof and the windows when the unlock button is pressed and held down for a while.

There have been many similar posts on this forum, and I have yet to see any malfunction reported. Put both remotes in clear sight to make sure it is not the button being accidentally pressed.

But at least with CA, they can turn the function OFF! Not sure if that is possible otherwise. Once it's off, no more worries.

turns out not to be the remote. Instead, they found the wiring harness connector to the driver's side lock assembly loose, tilted to one side, and the plug only partly in. Water inside the connector, likely it shorted the harness causing the windows to open.

Since there is no way to keep water out of the doors, the connector assembly is supposed to point down, so the connector socket hood covers the plug junction. Sideways and open, water was able to get in. Replaced the hood and plug, secured everything, and am told it shouldn't come back...

BTW, it turns out the dealer cannot just disable the window/roof override function on CA cars, without turning off the entire CA suite...bummer.

I had this same problem with my car and worked with the dealer to troubleshoot it for many months (non ca car). come to find out the dealer found on my car that the issue had to do with a faulty door accuator in which wasn't completely moisture sealed. They ended up replacing this unit with an updated model and then wrapped all of the accuators in a wrapping to keep them and the harnesses weather protected.

Thanks, good to know. If the problem comes back I'll definitely mention that to the service guys.

Well, this morning all the windows and sunroof were wide open, again! Back to the dealer. The "fix" didn't stay fixed very long, did it?

Very odd, but it is good to finally hear of an actual problem and solution for this issue. We've had at least a half dozen threads where windows and sunroof mysteriously opened. Wearing tight jeans is usually identified as the culprit. Interesting that it also could be the actuators, not user error after all.

This is definitely an electrical problem, because the doors were locked when I found everything open! I don't have the "relock" option set in the key preferences (deliberately), so if it had been the keyfob, the doors would have been unlocked if the button had been held down.

A thread in another forum about the same exact problem in an '08 328 suggests it could be the receiver amplifier or the "general module" as well as the lock module itself.

INCORRECT. This malfunction exists and IS NOT error. Happened to my 07 during a monsoon (8" of rain in one weekend). There is a housing in the A-pillar that is not properly weather-sealed and (in my case) pins 18/19 malfunctioned, opening my sunroof, windows and trunk overnight, outdoors in my driveway during a rainstorm.

Actuator housing is, yes, poorly engineered. I suppose the poor EE department couldn't get resources from drivetrain and suspension during the annual budget process. Thanks, Munich.

Was there any damage and did BMW fix/reimburse you for it?

Update: Dealer had the car for 2 1/2 days, brought the "regional engineer from BMW" in to look at it, then replaced the entire driver's side (master) lock assembly.

While they were at it, they tested the HPFP again, at my request (more long cranks) and this time it failed the pressure test, so that has also been replaced.

Picking it up in the morning...

Whoa!

Would have been nice to have a garage then, eh?

Comfort access doesn't work properly. I'm hoping there is a "reprogram" other than the entire computer, i.e. for the fobs or the system specifically.

It's pretty ridiculous to say your wife's purse and the fob inside is causing your stuff to open. So is the solution to take the fob away from your wife? Give me a break.

Again, I do understand, when the dealership doesn't know what to do, they're human too, what can they say? I'm sure they get pretty lame answers from BMW. On my car, the car locked when you want it to unlock. SA witnessed it. BMWNA told him it's normal.

Seriously? Wtf? Doesn't seem like a normal feature. Just my opinion, though
