In this video from the YouTube channel T-Tronic Automotive Auto Electrics in Mansfield, the team presents the case of a VW Golf that stopped starting. After performing diagnostics, it turned out that the problem was caused by a damaged gateway. Gateway is a control unit that is responsible for communication between various systems in the car. In this case, the gateway was flooded and corroded. The T-Tronic Automotive team ordered a new gateway module and reprogrammed it. After replacing the module, the car started working properly.
