What is the reason for the Golf 7 transmission failure preventing the car from starting?

The reason why the Golf 7 transmission failure prevents the car from starting is due to a malfunction in the dual clutch and the mechatronic unit. After the failure occurs, it is advisable to go to a 4S shop to check the dual clutch plates and the hydraulic control unit. The usual repair method is to first refresh the transmission software. If this still does not resolve the issue, it is necessary to replace the mechatronic unit and the dual clutch transmission assembly. The Golf 7 is a compact car under the Volkswagen brand, with a length, width, and height of 4259 mm, 1799 mm, and 1476 mm respectively. The wheelbase comes in two variants: 2631 mm and 2637 mm. The Golf 7 uses a 7-speed dual-clutch transmission, where one clutch controls the odd-numbered gears and the other clutch controls the even-numbered gears.
I've seen many cases of the Golf 7 failing to start due to transmission issues, but it's usually not directly caused by the transmission. Starting problems are often related to the ignition system, such as a dead battery, loose connections, or a faulty starter. When transmission fault codes appear in the Golf 7, they may affect the engine ECU communication through the control module, indirectly causing the system to lock and preventing ignition. It's recommended to first check if the battery voltage is normal and whether the battery terminals are loose. If there are warning lights on the dashboard, try restarting the system and then starting the car. The Golf 7 commonly experiences relay or fuse issues, which can trigger a chain reaction. If the problem persists, scan the OBD for specific fault codes as soon as possible to avoid minor issues escalating into major transmission or engine repairs, which can be time-consuming and costly. Don't wait—get it checked at a workshop early, safety first.
