Inspecting fuel filter with pressure control valve
Inspecting fuel filter with pressure control valve
The fuel filter and the pressure control valve are integrated in a component.
Fitting location:
   
The fuel filter with pressure control valve-arrow- is located on the right of the fuel tank.
Special tools and workshop equipment required
t  Pressure gauge appliance (e.g. -V.A.G 1318 - )
t  Adapter (e.g. -V.A.G 1318/10 -)
t  Adapter (e.g. -V.A.G 1318/11 -)
t  Adapter (e.g. -V.A.G 1318/16 -)
Test conditions
l  Fuel pump relay o.k., test → Chapter
l  Testing flow rate of the fuel pump O.K. → 1.0/37; 1.4/44; 1.4/50 Engine -Mechanics; Rep. Gr.20
l  Line connections or fuel lines from the fuel filter with pressure control valve to fuel rail O.K.
Test sequence
  Caution
The fuel system is under pressure! Place a cloth around the connecting point before releasing hose connections or when opening the system. Then reduce the pressure by carefully removing the hose or cap.
  S24-0422
–  Remove fuel feed line -1- from the connection to the fuel rail -2- and connect to pressure gauge appliance -V.A.G 1318- with adapter -V.A.G 1318/16- und -V.A.G 1318/11-.
–  Connect the pressure gauge appliance -V.A.G 1318- to the fuel rail -2- with adapter -V.A.G 1318/10-. Open the shutoff cock of the pressure gauge appliance (lever in flow dircetion -arrow-).
–  Start engine and run in idle.
–  Measure fuel pressure.
   Specified value: 2.9 bar...3.1 bar (0.29 MPa...0.31 MPa)
If the specified value is not reached:
–  Testing fuel pump → 1.0/37; 1.4/44; 1.4/50 Engine -Mechanics; Rep. Gr.20.
If fuel pump is o.k.:
–  Replace fuel filter with pressure control valve → 1.0/37; 1.4/44; 1.4/50 Engine - Mechanics; Rep. Gr.20
  Note
Before removing the pressure gauge appliance reduce fuel pressure by opening the shutoff cock. While doing so grip vessel before the connection.
