Solution

1. Preparation

Ensure the vehicle is in park or neutral with the parking brake engaged.
Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cover if applicable.
2. Disconnect the negative terminal first, followed by the positive terminal.
3. Remove the battery hold-down clamp using a socket set.
4. Carefully lift out the battery.
5. Inspect battery for physical damage or leakage.
6. If the battery is faulty or below 12.4 volts, replace it with a new battery that meets OEM specifications (typically Group 49 or 94R for BMW).
7. Install the new battery by reversing the removal steps, ensuring terminals are tightened properly (secure to 10 Nm for battery terminals).

3. Starter and Wiring Inspection

Sub-steps:
1. Visually inspect the starter motor and solenoid connections for any signs of damage or corrosion.
2. Check the electrical wiring leading to the starter for fraying or breaks.
3. Test the starter motor by attempting to engage it directly with a jumper wire; if it engages, the starter is likely functional.
4. If the starter does not engage, it may need replacement.
