why does my Skoda Octavia's battery keep dying overnight

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, ammeter, basic socket set, and safety gloves.
• Disconnect the negative battery terminal using a socket wrench.
• Ensure all tools and parts are organized before beginning work.

2. Address Parasitic Draw

• Sub-step 1: Reconnect the battery and use an ammeter to measure current draw.
• Sub-step 2: If the draw is excessive, identify the offending circuit by removing fuses individually until the current draw drops to an acceptable level.
• Sub-step 3: Once identified, further investigate the specific circuit for faulty components (e.g., lights, radio) that may be causing the draw.

3. Replace Faulty Components

• Sub-step 1: If a faulty component is found, remove it using a socket set or screwdriver as necessary.
• Sub-step 2: Install a new component (e.g., light switch, radio) by reversing the removal steps and ensuring all connections are secure.
• Sub-step 3: Reconnect the battery terminal and test the new component to ensure it functions correctly.

4. Battery Check and Replacement

• Sub-step 1: If the battery is old or faulty, remove it by loosening the hold-down clamp and disconnecting both terminals (negative first).
• Sub-step 2: Install a new battery by securing it in place and connecting the terminals (positive first).
• Sub-step 3: Check the battery voltage post-installation to ensure it is fully charged.
