Car Forum / BMW Cars / April 20042004 330ci Convertible - trunk latch problem
I have a 2004 330ci convertible. I am having one minor problem that the dealer so far hasn't fixed. the electronic trunk unlatch mechanism doesn't work. I am referring to the button under the dash (driver's side) and the button under the trunk lip. I can only get into the trunk using the key, or the button on the key fob. when I first got the car, it was an intermittent problem. now it just doesn't work at all. originally, the service guy found a 'fault' in the computer chip for the alarm system (which I don't have one), and he reset that. the trunk worked briefly, and has now stopped again. anyone else with a similar problem, and a fix?? thanks, alan Are you sure you haven't accidentally disabled the interior release and the button under the trunk lip by inserting the master key in the trunk keylock and twisting it to the right (so the trunk keylock slot is horizontal)? If you have done this intentionally or not, it is a feature not a bug (part of the anti-theft system whereby you can give the valet key to a parking lot attendant and they won't be able to get into the trunk). You can re-enable the releases by inserting the master key and turning 1/4 turn to left, so the trunk keyslot is vertical. Rick Peeples > I have a 2004 330ci convertible.

I did however, try the key in the trunk key release, and it only has one position -- horizontal!! alan > Are you sure you haven't accidentally disabled the interior release and the > button under the trunk lip by inserting the master key in the trunk keylock [quoted text clipped - 25 lines] > > thanks, > > alan I have a 2004 325 convertible with a very similar problem, but the trunk release hasn't yet completely stopped working. It does, however stick in the open position when you press the truck release inside the car or on the trunk lid. I have to "press-n-wiggle" the truck lid release to get it in the unlatched position so the trunk will latch closed again. So far the dealer has been unable to identify why it is sticking. > Rick, > [quoted text clipped - 39 lines] > > > thanks, > > > alan Hmmm. Interesting, I wouldn't have thought there would be a difference between sedan and convertible vis-a-vis the locking systems... my 330i also has the glove box valet lock. Actually, you'd think that the convertible would want control over trunk locking even more, because the cabin is so accessible! It just doesn't seem right that your trunk keylock doesn't have the vert/horiz. switch. You might ask your dealer about this, I think this is supposed to be a standard feature across the series. And if yours is for some reason stuck or malfunctioning, it sure might explain the problem you're having with the interior release and the trunk lid button. Rick Peeples > Rick, > [quoted text clipped - 39 lines] > > > thanks, > > > alan If you listen closely, you can hear 3 distinct sounds when opening the trunk via the trunk lid latch: 1) solenoid actuation 2) trunk latch releasing 3) trunk latch returning to the lock position When it malfunctions, you will hear only sounds 1 and 2. If you press the trunk lid latch again you will hear the latch go to the closed position, allowing it to lock when the trunk is shut. What's curious is that this only happens occasionally -- I sat there with the service manager and we got it to malfunction about 3 out of 10 tries, so it does work normally most of the time. There is obviously some sort of electro-mechanical failure. Let's hope a fix will be discovered soon. > Hmmm.

Here's what page 35 of the Manual says: The lock Only the master keys fit in the lock for the luggage compartment lid, refer to page 30. To secure separately Lock the glove compartment using the master key. This locks the luggage compartment lid and disconnects it from the central locking system. This feature can be used to prevent unauthorized access to the luggage compartment when you surrender the spare key only, refer to page 30. This can be advantageous for valet parking, for example. To open from the outside Press the button in the handle recess: the luggage compartment lid opens slightly. The luggage compartment is lit when the luggage compartment lid is opened. Manual operation In the event of electrical malfunction Turn the master key all the way to the left – the luggage compartment lid will open slightly. The luggage compartment is locked again as soon as you close the lid. To open from the inside* If the luggage compartment lid has not been locked separately, you can open it with this button in the footwell on the driver's side when the vehicle is stationary.

Anyone know how the glove box switch works? Is it just an open/close mechanical switch or a control module that puts a signal on a bus?
