2.0 TFSI & TSI low-pressure output stage Fuel pump control unit BAR-TEK Motorsport 21tf398 - сервиз

Control unit for the fuel pump for all TFSI & TSI engines. If you have installed a upgrade- fuel pump, it can often happen that it does not always work correctly. This is usually due to a defective pump. Our experience has shown that this is not the case, but that the control unit is defective and cannot cope with the extra power of your upgrade pump. This is where the output stage or control unit comes into play. This should always be replaced together with the pump in order to really be able to call up the performance of your upgrade pump. The control unit is simply plug & play replaced No further changes e. g. to the engine software necessary with standard software! After installation, check the fuel gauge and readjust with VCDS if necessary.Maximum current consumption: 17 amps. If your pump does not function correctly, please have the software tuner programme the pump control (PWM signal) to series!
