Disconnect hose -1- of the feed line from the fuel filter
inlet (filter version with integrated fuel pressure regu-
lator).
–
Disconnect hose -1- of the feed line from the fuel filter
inlet (filter version with separate fuel pressure regula-
tor).
–
Connect pressure gauge -V.A.G 1318- with adapter
-V.A.G 1318/17- to the hose -1-.
–
Repeat flow rate test.
If the minimum flow rate is reached:
–
Replace fuel filter.
If the minimum flow rate is again not reached:
–
Remove the fuel delivery unit and check whether the
pump strainer is not clogged up.
If no fault was detected until now:
–
Replace the fuel delivery unit.
The flow rate was reached but a fault in the fuel supply
system is suspected (e.g. temporary failure of the fuel
supply system).
–
Check the power consumption of the fuel pump as fol-
lows:
–
Connect all released fuel lines.
–
Connect the voltage measurement multimeter with the
current pliers to the line of contact -1- of the plug con-
nection at the fuel pump.
–
Start engine and run in idle.
–
Measure voltage consumption of the fuel pump. Spec-
ified value: max. 8 A.
Note
If the failure in the fuel supply system is occasional the
test may be performed during a test drive. The assistance
of a 2nd mechanic is required.
If the power consumption is exceeded:
–
