🔧 Repair Overview
Battery Replacement (Car) is one of the most common repairs for 2013 BMW 3 Series. This repair involves replacing the damaged electrical component with a new or refurbished part. The process typically takes 30 min and requires easy skill level.

Step-by-Step Process
Step 1:
Unlock your trunk.
This can be done with either the remote or the trunk release button located on the driver's side footwell area.
Using the trunk handle, lift the trunk to it's highest position.
Step 2:
Using the appropriate trim tool, carefully remove all ten rivets from the trunk liner.
Step 3:
Pull on the green tab to release the inner trunk release handle.
After this, the trunk liner should be loose.
Carefully remove the liner and put it off to the side for later reassembly.
Step 4:
Using either a 10 mm socket or an open-end 10 mm wrench, turn the nut counterclockwise to loosen it and remove the bracket that secures the inner taillight.
An open-end wrench was used in this guide, however, both tools work for removing the retaining nut.
Step 5:
From underneath the inner taillight, push the housing with enough upward force to separate it from its socket.
Be careful when pushing the housing, as the connector is still attached to the inner taillight.
Step 6:
Tilt the inner taillight enough to gain access to the connector on the underside.
Firmly press the locking tab in the center of the connector.
Pull downwards on the connector to disconnect the inner taillight housing.
Step 7:
Prepare your new taillight for reassembly.
Responsibly recycle your old inner taillight if it is no longer functional.
