Removing And Installing Fuel Pressure Sender For Low-Pressure G410 - Skoda Octavia III 2013 Workshop Manual

– Switch on the pressure gauge - VAS 6394/1- - to do so, press
button -A- once briefly.
Note
If the button -A- is pressed for 2 seconds, the illumination is
switched on for 20 seconds.
The pressure manometer - VAS 6394/1- should indicate 0 bar; if
this is not the case, press the button -C- once briefly for the zero
value comparison.
– Connect the pressure line of the pressure manometer - VAS
6394/1- to the adapter - VAS 6394/2- .
– Start engine.
– Compare the displayed pressure on the pressure manometer
- VAS 6394/1- with the actual value at the vehicle diagnostics
tester .
• The pressures may deviate a maximum 0.5 MPa (5 bar) from
one another.
– If the deviation is greater than 0.5 MPa (5 bar), test a new Fuel
pressure sender - G247- .
WARNING
The fuel system is under pressure! Before opening the system,
you must remove the pressure in the high-pressure system
⇒ page 3 .
– Screw in the new Fuel pressure sender - G247- into the pres‐
sure manometer - VAS 6394/1- .
– Repeat the test with the new fuel pressure sender - G247- and
compare both measured values.
If the measured values do not correspond now:
– Check electrical wiring between Fuel pressure sender - G247-
and engine control unit⇒ Current flow diagrams, Electrical fault
finding and Fitting locations.
If the measured values now correspond:
– Install the new Fuel pressure sender - G247-
