Diesel fuel system diagnostic devices
Instrument for measuring high and low pressure in VW/Audi FSI (GDI) engines and similar (PSA, BMW-MINI)
FSI PRESSURE MEASUREMENT
FSI engines operate in the same way as Common Rail diesel engines, meaning they are equipped with a low-pressure circuit and a high-pressure circuit.
Set equipment:
- 0-250 bar gauge with a tee for hose connection
- 0-10 bar gauge with a tee for hose connection
- Hose M12x1.5 / M12x1.5 - 2 pcs
- Hose M12x1.5 / M14X1.5 - 2 pcs
The instrument can measure both circuits and is equipped with gauges:
– up to 10 bar (low pressure)
– up to 250 bar (high pressure)
INSTRUCTION
– Attach hoses to the tee,
– Unscrew the steel pipe connecting the high-pressure "rails" to one of the injectors, and screw the hose ends to the rail and the injector fitting.
Low pressure
Initially, connect the gauge with a range of 0-10 bar.
When the engine is off and the ignition key is in the "OFF" position, the pressure must be 0. Turn the key (without starting the engine). Immediately after activating the injection, the low-pressure pump should be activated, and the pressure should reach approximately 5-6 bars. If the pressure does not reach the required value, the low-pressure circuit is not functioning correctly. Therefore, check the low-pressure pump, filter, etc.
High pressure:
- Connect the tee with the 0-250 bar gauge to the hoses remaining in the system
Start the engine and check if the pressure in the stationary vehicle is approximately 50 bars, and when accelerating, the pressure reaches between 100 and 110 bars. If the pressure in the stationary vehicle is significantly lower than 50 bars, the high-pressure pump or regulator is damaged. If the pressure is higher than 110 bars, the regulator is damaged.
