  • Switch on tester -VAS 6394/1- by pressing button -A- once briefly.
Note When button -A- is pressed for 2 seconds, the illumination is switched on for 20 seconds. If tester -VAS 6394/1- does not indicate 0 bar, zero the tester → Operating instructions.
  • Connect vehicle diagnostic tester.
  • Start engine and run at idling speed.
  • Select “Engine electronics” in the self-diagnosis program.
  • Then, select “Measured values”.
  • Select “Fuel pressure” from the list.
  • Compare pressure displayed on tester -VAS 6394/1- with actual value displayed on vehicle diagnostic tester.
  • Watch the fuel pressure on the vehicle diagnostic tester.

A maximum pressure deviation of 5 bar is permissible.

  • If the deviation is greater than 5 bar, renew fuel pressure sender - G247-.
  • Repeat test with new fuel pressure sender - G247- and compare both measured values.
  • If measured values are now the same, install new fuel pressure sender - G247-.
  • If measured values are not the same again, check electrical connection between fuel pressure sender - G247- and engine control unit -J623- → Current flow diagrams, Electrical fault finding and Fitting locations.
