what does the B1460 code mean in my Volkswagen Golf MK6 (2009-2014)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent any electrical shorts.
• Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Clean Battery Connections

• Remove the battery terminals (negative first, then positive).
• Clean the terminals and cable ends with a wire brush and a solution of baking soda and water to remove corrosion.
• Reconnect the terminals, ensuring they are tight and secure.

3. Test and Replace Battery (if necessary)

• If the battery voltage is below 12.4V and does not hold a charge, remove the battery.
• Replace with a new battery of the same specification.
• Reconnect the battery terminals, ensuring the positive is connected first.

4. Inspect and Replace Alternator (if necessary)

• If the alternator does not charge the battery above 13.7V when the engine is running, remove the drive belt.
• Disconnect the alternator wiring harness and remove the mounting bolts.
• Replace with a new alternator and reassemble in reverse order, ensuring all electrical connections are secure.

5. Final Checks

• Reconnect the negative battery terminal.
• Start the engine and check the voltage at the battery again to confirm proper charging.
