Solution

1. Preparation

Tools Needed: Multimeter, socket set, jumper cables, wrench set, safety goggles.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Battery Inspection and Replacement

Sub-step 1: Reconnect the battery and check the voltage with a multimeter. If the voltage is below 12.4 volts, charge the battery using an appropriate charger.
Sub-step 2: If the battery is old or unable to hold a charge, replace it with a new one (ensure correct specifications: typically 12V, 70-80 Ah for X3).
Sub-step 3: Clean battery terminals and cable connections to ensure a solid connection.

3. Starter Motor Testing and Replacement

Sub-step 1: If the battery is in good condition, locate the starter motor (usually near the bottom of the engine near the transmission).
Sub-step 2: Connect jumper cables to the starter motor's positive terminal and ground, then attempt to start the vehicle. If it engages, the starter may be faulty.
Sub-step 3: If the starter motor fails to engage, remove the starter (typically involves removing bolts and electrical connections) and replace it with a new starter motor.
Sub-step 4: Reconnect all electrical connections securely and reattach the starter with the specified torque (usually around 25-30 Nm).
