Bmw 328 xi luggage compartment lid does not open

Luggage Compartment Lid
The luggage compartment lid module receives a voltage signal from the driver door module (DDM) when either the button on the driver door trim panel, the keyless entry keypad, or the transmitter is pressed (twice on the transmitter). Voltage is then supplied to the luggage compartment lid latch, opening it. Using the luggage compartment lid key operates the latch mechanically, resulting in manual-only operation of the lid. There are two switches in the latch. One is monitored by the luggage compartment lid module to sense if the latch is closed. The other switch in the latch is monitored by both modules (LCM and luggage compartment lid module) and is used for disabling the anti-theft system, which is contained within the LCM. The luggage compartment lid module powers the lid motor to move the lid to the full-open position when it senses the latch has been opened. Optical sensors within the lid motor are monitored by the module to determine when to turn off power and which circuits should be powered or grounded to the lid motor. When one of the buttons is depressed with the lid open, the DDM sends a signal to the luggage compartment lid module which powers and grounds the correct circuits to the lid motor and lowers the lid until the latch closes. The module senses the latch closing through the lid latch switch that is monitored. At this time, the module powers the closing motor, slowly pulling the lid to a fully closed position. Two switches within the closing motor are monitored by the module to determine when the closing motor is fully down or up. The module has a vehicle speed output (VSO) (circuit 679) signal that is used to shut down the system if there is a VSO of approximately 5 kph (3 mph) or more. For diagnostics, the module uses the ISO-9141 circuit 70 that is included in the DLC (data link connector). Whenever battery power is lost to the luggage compartment lid module, luggage compartment lid motor or the luggage compartment lid closing motor; the system must be initialized.

NOTE: The luggage compartment lid motor is equipped with an optical sensor that the module uses to determine if the lid is closing on foreign materials based on lid speed. If the module detects this occurring, power and ground will be reversed to the lid motor and the lid will open.

1. Verify the customer concern by operating the luggage compartment lid using the four different methods (driver door trim panel button, transmitter button, keyless entry keypad and key) to duplicate the concern.

1. Visually inspect for obvious signs of mechanical or electrical damage.

• Luggage compartment lid motor
• Luggage compartment lid closing motor
• Luggage compartment lid latch
• Luggage compartment lid and hinges

• Battery junction box (BJB) fuse(s):

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. Verify the two grounds (G204, G401) are clean, tight and free from corrosion. Remove and clean to make sure.

1. Monitoring the PIDS in the luggage compartment lid module can verify the DDM is sending the lid-open signal to the lid module. They can also be used to determine if the latch switches, the lid switches and the lid motor sensors are all providing the luggage compartment lid module with the correct and necessary information to operate the system. The VSO input can shut the system down if there is a signal indicating 5 kph (3 mph) or more.

1. If the electrical lid operation is ok, but the key is ineffective, refer to Section 501-14 .

1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) located under the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the program card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.
   • If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.

1. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with:
   • CKT 914, CKT 915 or CKT 70 = ALL ECUs NO RESP/NOT EQUIP, refer to Section 418-00 .
   • NO RESP/NOT EQUIP for luggage compartment lid module, Go To Pinpoint Test A .
   • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the luggage compartment lid module.

1. If the DTCs retrieved are related to the concern, go to the luggage compartment lid module Diagnostic Trouble Code (DTC) Index to continue diagnostics. For lighting control module (LCM) concerns, refer to Section 419-10 for a complete DTC index.

1. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart.

Check that the hydraulic overide screw (if it has one) has not come loose to release pressure. Make sure all windows are down. Make sure boot isn't locked. Test luggage switch hasn't failed by disconnecting at the plug and get your multi meter and check for a complete circuit at the switch itself when depressed. Failing all that manually lower the roof and then refit and try then. This has worked on a peugeot 207 should also work with others

Victoria, Fold down rear seat back, to access trunk space. Your vehicle is equipped with a release handle that provides a means of escape for children and adults if they become locked inside the trunk/luggage compartment.The handle is located inside the trunk/luggage compartment either on the luggage compartment door (lid) or near the tail lamps. It is composed of a material that will glow for hours in darkness following brief exposure to ambient light.
Pull the handle and push up on the luggage compartment door (lid) to open from within the luggage compartment.
Check the attached links,instruction and guides, Good luck

Anti-Theft - Perimeter The anti-theft perimeter protection feature is controlled by the front electronic module (FEM), the rear electronic module (REM), and the driver door module (DDM). The alarm can be armed using:

• the LOCK button in the remote keyless entry (RKE) transmitter to the DDM, which sends a message through the standard corporate protocol (SCP) communications network to the FEM.
• the driver or passenger door lock switch if the corresponding door is open when LOCK is actuated.
• the key in the driver door lock cylinder.
• the RKE keypad by pressing 7/8 and 9/0 simultaneously.

The FEM and REM then monitor all features, which activate the alarm in the event of an unauthorized entry.
The luggage compartment lid lock cylinder does not disarm the vehicle's perimeter alarm. The luggage compartment alarm can be temporarily inhibited through the luggage compartment lid disarm switch, located in the luggage compartment lock cylinder or by opening the lugguage compartment with the RKE transmitter or the RKE keypad. Once the luggage compartment lid closes, the perimeter alarm system immediately starts monitoring the luggage compartment. The perimeter alarm can only be disarmed:

• by unlocking the vehicle using the RKE transmitter.
• by unlocking the vehicle using the driver door lock cylinder switch.
• by cycling to RUN a valid programmed key in the ignition switch.
• by entering the correct vehicle unlock code on the RKE keypad.

Additionally, an ignition switch tamper circuit and a signal hardwire line from the FEM to the REM are monitored.
If any of the above features receive any activation once the alarm is armed, the alarm activates the visual and audible alerts. ......

get the compression test done to see the condition of your head gasket

my 07 525 xi won't start ether i have change my batteries,start/stop switch,cas board and get new keys 4 months ago and now history repeat its self again

anything stopping it from opening up?

i would check to see if the luggage compartment (trunk) isn't expanded. If it is the convertible top module wont allow the top to move. If the trunk is open or there is a problem in the wiring and a check control message is displayed the top won't open either
