The p1434 BMW code signifies a malfunctioning diagnostic module for detecting tank leakage. This device, known as DMTL and created by Bosch in the late 1990s, is a compact unit featuring an air pump, electric motor, switching valve, reference orifice, and heater housed together. There is usually an external air filter connected to the assembly via a hose and placed in a distant spot.
