how to resolve the no sound issue in Volkswagen Golf MK7 (2015-2019)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
• Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check Fuses

• Locate the fuse box (typically under the dashboard or in the engine compartment).
• Identify the fuse for the audio system (consult the owner's manual for the specific location).
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; replace if blown with the same amperage rating.

3. Inspect Connections

• Remove the trim panel around the audio system (use a trim removal tool).
• Check all wiring harnesses for secure connections to the head unit and amplifier.
• Look for any damaged wires or corrosion on connectors. Repair or replace as necessary.

4. Test the Speakers

• Disconnect the speaker wires from the audio unit.
• Using a multimeter, measure the resistance of each speaker (should read between 4-8 ohms).
• Replace any non-functional speakers with OEM or compatible units.

5. Reset the Infotainment System

• With the ignition on, hold the power button on the infotainment unit for about 10 seconds until the system resets.
• Allow the system to reboot and test audio output.

6. Reassemble

• Reattach the trim panel once repairs and checks are complete.
• Ensure all connections are secure and tidy.
