Why does the Volkswagen P gear keep flashing and the car won't start?

[LaElle]

Volkswagen P gear keeps flashing and the car won't start because the transmission control unit detects a fault, causing the gear indicator light to flash and preventing the engine from starting. The following are specific reasons for the P gear flashing: 1. The P gear keeps flashing because the handbrake is not fully released. In most cases, adjusting the handbrake to the correct position will solve the issue. 2. Red P: A red P light indicates that the parking brake system is engaged, meaning the handbrake is pulled tight. It is displayed in red on the instrument cluster as a normal status, not a fault. If it lights up or flashes along with other warning lights, such as the ABS light, it indicates a system fault. 3. Yellow P: A yellow P light usually indicates a stored fault in the parking brake or ABS system. Further inspection is required to confirm and resolve the issue. 4. Green/Blue P: A green or blue P light indicates that the AUTO-HOLD system (automatic parking brake) is functioning normally. The P light illuminates to alert the driver when the system is active.
