BMW General Module 5 Removal Procedure for E85 Z4 Vehicles

Tools required:
#2 Philips screwdriver
8mm nut driver
10mm socket

Step 1. Disconnect the battery. The battery is located in the trunk, under the false floor panel. Use the 10mm socket to disconnect the battery negative terminal of the battery. See picture.

Step 2. Remove the two philips screws just below the glove box. See picture.

Step 3. Pull down the panel. The GM5 module will be mounted to the panel. See picture.

Step 4. Use the 8mm nut driver to remove the left and loosen the right hex head screws holding the module to the panel.

Step 5. Disconnect the 3 connectors. Start by disconnecting the connector on the right. This connector has an outer sleeve that slides to the right. You might need to insert a flat blade screwdriver just to the right of the wires to get it started. See picture below left. The next two connectors have a white latch lever that needs to be rotated 90 degrees. See picture below right.

Reinstallation

Step 1. Preform steps 1 through 5 above in reverse order.

Now that you got the module out send it to someone who knows what they're doing. GM5 Repair Service

Notes: When the GM5 module is reinstalled after repair it is good to go. There is no need to go to the dealer for recoding or programming or anything like that. It should just work. When testing the door locks make sure that the driver's door is closed. I have gotten many calls where the customer says that the door locks don't lock now. I tell them to shut the driver's door and that solves the problem. The module will not let you lock the doors if the driver's door is open. The passenger doors can be open, but, not the driver's.
