Code P1408 Volkswagen Description
The P1408 code in Volkswagen vehicles indicates that the EGR (Exhaust Gas Recirculation) temperature sensor signal is too high. The EGR system is crucial for reducing emissions by recirculating a portion of the engine's exhaust back into the intake system. The temperature sensor monitors the temperature of the exhaust gases entering the EGR system. When the sensor detects a signal that is higher than the specified range, it triggers the P1408 code.
