Aftermarket battery installation diy inpa bmw

Installing an aftermarket battery in your BMW can be a rewarding experience if done correctly and safely. This article will guide you through the process of installing an aftermarket battery with INPA (BMW ECU Flasher) programming on Windows XP or later versions.

Before starting, ensure that you have the necessary tools and materials:

* A replacement or used rain sensor

* An OBD2 adapter for your BMW's CAN bus system

Step 1: Prepare Your Vehicle

1. Make sure your vehicle is parked in a well-ventilated area away from any flammable sources.

2. Engage the parking brake and disconnect the negative battery cable.

Step 4: Remove Battery Tray

For E36 models:

1. Release the battery tray catch (usually located at the bottom of the trunk).

2. Slide out the tray towards you.

For E39/E53 models:

1. Locate the air intake ducting on the driver's side.

2. Disconnect any electrical connectors and T-hose connections.

3. Remove the panel to access the battery area.

Step 5: Install New Battery

1. Carefully lift out the old battery using a pair of gloves or slip-resistant hand protectors.

2. Position the new battery in its holder, ensuring proper alignment with existing mounting points.

3. Securely fasten all retaining clips and brackets to prevent movement during installation.

Step 6: Reconnect Battery Tray/Cables

1. Reverse Step 4 for E36 models:

a) Slide the tray back into place.

b) Engage the catch mechanism at the bottom of the trunk.

2. For E39/E53 models:

a) Reattach any T-hoses and electrical connectors to their original positions on both sides of the battery compartment.

Step 7: Start Engine and Check

1. Connect the negative (-) terminal first, followed by reattaching all other connections in reverse order (positive (+), then accessories).

2. Turn the ignition switch to 'start' without pressing the start button if your vehicle has an automatic transmission or shift into gear for manual models.

3. Allow a few seconds for the system to stabilize before turning off the engine again with the key once it starts up normally; otherwise, repeat this process until everything works as expected!

4. Press and hold Shift + F9 on your keyboard while in INPA's main menu (this may take some trial-and-error). The 'E36' menu should now be visible under 'Engine/ECU'.

5. Click through the various sub-menus to ensure all settings are at their default values before proceeding further with any additional programming tasks required based upon your specific vehicle make & model year etc...
