When the ECU module, the engine start control unit, of the Volkswagen Golf mk5 is not functioning, it is necessary to check and replace the fuse. The relay in question is located inside the fuse box under the bonnet, near the battery.

To maintain the relay, open the fuse box and connect a tester in place of the removed black relay, then work on the ECU with electrical cables to make modifications and fix the relay. Once finished, turn on the vehicle's ignition and engine to check that everything is working correctly.
