5. Try a Known Good Amplifier (If Possible): If you have access to a known good amplifier, try swapping it into the car to see if the problem goes away.

Coding the Amplifier

If the amplifier is replaced, coding might be required to ensure that it is properly recognized by the car’s computer system. Use VCDS to code the amplifier according to the car’s configuration.

7. Why Swapping Speakers Didn’t Resolve the Issue

The original poster mentioned that another workshop swapped the speakers from left to right, but the problem remained on the left side. This indicates that the problem is not with the speakers themselves. The issue is likely in the wiring, the amplifier, or the radio unit.

What Does This Tell Us?

Since swapping the speakers didn’t change the problem, we can eliminate the speakers as the cause. This focuses the troubleshooting on the following areas:

• Wiring: The wiring between the radio/amplifier and the left-side speakers.
• Amplifier (If Applicable): The amplifier’s output for the left-side speakers.
• Radio Unit: The radio’s internal circuitry that drives the left-side speakers.

8. Understanding CAN Bus Communication Issues

The CAN (Controller Area Network) bus is a communication network that allows the different control modules in a car to communicate with each other. If there is a problem with the CAN bus, it can cause a variety of issues, including audio problems.

How CAN Bus Problems Can Affect the Radio

• Loss of Communication: If the radio cannot communicate with the CAN Gateway, it won’t be able to receive important information, such as the car’s speed, engine RPM, or steering angle. This can cause the radio to malfunction or shut down completely.
• Incorrect Coding: If the CAN Gateway is not properly coded, it might not be able to communicate correctly with the radio.
• Data Corruption: Problems with the CAN bus can cause data corruption, which can lead to unpredictable behavior from the radio.

Diagnosing CAN Bus Problems

• VCDS Scan: Perform a VCDS scan to check for any fault codes related to the CAN bus.
• Wiring Inspection: Inspect the CAN bus wiring for any signs of damage.
• Resistance Test: Use a multimeter to check the resistance between the CAN high and CAN low wires.
• Oscilloscope: Use an oscilloscope to check the CAN bus signals for any abnormalities.

9. TV Tuner Faults: Are They Related?

The scan data also shows several faults related to the TV tuner (Address 57). These faults include:

• 03393 – Supply Voltage for Card Reader: Open or Short to Plus
• 03210 – Video Signal Red: Open or Short to Plus
• 03211 – Video Signal Green: Open or Short to Plus
• 03212 – Video Signal Blue: Open or Short to Plus
• 03213 – Video Signal Synch: Open or Short to Plus

Likely Not Directly Related

While these faults indicate problems with the TV tuner, they are likely not directly related to the radio’s audio problem. The TV tuner is a separate module that is responsible for receiving and decoding television signals. However, it’s important to note that electrical problems can sometimes be interconnected. A short circuit in the TV tuner wiring could potentially interfere with the radio’s operation, but this is less likely.

Troubleshooting the TV Tuner

• Inspect the TV Tuner Wiring: Check the wiring harness connected to the TV tuner for any signs of damage.
• Check the TV Tuner Fuse: Locate the fuse for the TV tuner and check if it’s blown.
• Disconnect the TV Tuner: Try disconnecting the TV tuner completely to see if it has any effect on the radio’s audio problem.
