Troubleshooting Fuel Pump Relay Issues

If you are experiencing issues with your Audi S4's fuel pump relay, there are a few things you can do to troubleshoot the problem. First, check the fuse for the fuel pump relay.

Finally, test the new relay to make sure that it is working correctly.

By following these steps, you can quickly and easily troubleshoot and replace your Audi S4's fuel pump relay. Remember, keeping your vehicle in peak condition is essential for its longevity and reliability.
