What does it mean when the gear display flashes and a wrench icon appears in the Passat?

The flashing wrench icon is a reminder for car maintenance, while the flashing gear light indicates a fault in the transmission control system. It is recommended to visit a repair shop to read the fault codes using a diagnostic tool. Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Symptoms of Transmission Control System Fault: Delayed upshifting of the automatic transmission; Automatic transmission fails to upshift; The car cannot move: regardless of whether the gear shift lever is in reverse or forward gear, the car cannot move; The car can move a short distance after starting, but cannot move after warming up slightly.
When the gear indicator flashes and the wrench icon appears on my Passat, I immediately think the vehicle needs attention. The wrench is typically a maintenance reminder light, indicating it's almost time for service, such as an oil change or routine maintenance; while the flashing gear indicator might involve transmission issues, like a sensor malfunction or insufficient transmission fluid. Ignoring these problems could lead to shifting difficulties or even engine damage. I've experienced similar issues with my older Volkswagen before—it was caused by a faulty gear position sensor back then. After a simple inspection, replacing it with a new one solved the problem at a reasonable cost. I recommend avoiding further driving, especially on highways, as this may affect control. It's best to drive to the nearest repair shop for a diagnostic scan to pinpoint the exact cause, and consider doing basic maintenance to prevent recurring issues.
