FSI/GDI Digital High and Low Pressure Tester

Device for measuring the high and low pressure FSI (VW/Audi engines  and GDI the like (PSA BMW-MINI)

PRESSURE MEASUREMENT FSI

FSI work in the same way as common rail diesel engines, that is, are equipped with a circuit of low pressure and high pressure circuit.

Equipment: 

pressure gauge 0-250 bar with a T-piece for connecting hoses

pressure gauge 0- 10  bar with a T-piece for connecting hoses

- M12x1.5 / M12x1.5 hose - 2 pcs

- M12x1,5 / M14X1,5 hose - 2 pcs

FSI engines work in the same way as CommonRail diesel engines, i.e. they are equipped with a low pressure circuit and a high pressure circuit.

The instrument is able to measure both circuits, it is equipped with pressure gauges:

- up to 10 bar (low pressure)

- up to 250 bar (high pressure) 

INSTRUCTION

- Attach the hose to the tee,

- Unscrew the steel cord connection "bus" a high-pressure injector and the hose ends to the terminal screw and nozzle of the injector.

Low pressure

At the beginning   join gauge of 0-10 bar .  

When the engine is off and the ignition key to "OFF", the pressure must be equal to 0. Turn the key (without starting the engine). Immediately after the injection is activated, enable the low pressure pump and the pressure must reach values of about 5-6 bar. If the pressure does not reach the required value, low-pressure circuit is not working properly. Therefore check the low pressure pump, a filter, and the like.

High pressure :

        Hose remaining join in a tee with pressure gauge 0-250 bar

Start the engine and check if the pressure in the stationary vehicle is equal to about 50 bar, and during acceleration the pressure reaches a value between 100 and 110 bar. If the pressure in a stationary vehicle is much lower than the 50 bar high pressure pump or the controller is defective. If the pressure is higher than 110 bar, the regulator is defective.
