Dmtl Pump Bmw N54

The DMTL system simply controls "Evaporative Emissions" or evaporation of fuel into the atmosphere, and has NOTHING to do with how your engine runs.

DMTL is in the driver's wheel well, is evap-related. They do fail and throw code, shouldn't hurt anything or be related to the fuel pump.

For the system to achieve a good pressure, the DME (BMW's term for the ECM) pulses a vacuum controlled solenoid as the pump is operating. The DME monitors the diaphragm movement via the DMTL/LDP reed valve's feedback and compares it to stored DME vacuum solenoid frequency. DMTL Pump -- part number 16136752551 DM-TL, or Diagnosis Module.

Pressure is applied to the components of the fuel supply system during the tank leak measurement procedure. The internal solenoid valve in the DMTL (14, Fig. 1) closes the line to the atmosphere The DMTL pump is activated As a result, the fuel supply system is now a closed system (from the DMTL valve up to the fuel evaporation control valve) and the pressure is increased in the entire.
