NOTE: The operative must gather information regarding the Customer experience regarding when the issue occurred for example: Preconditions, warning lights and driveability at time issue occurred, details when the vehicle was last refuelled and the grade of fuel used
The operative must now use the information contained within the “Measure” section to determine the correct analysis and repair procedure.
Revision history
• TPI 2061171/7 - Addition of DTC P018B00 - Fuel Pressure Sensor "B" Circuit Range/Performance with symptom code 17871 within the
customer statement/workshop findings section
•
TPI 2061171/8 - Inclusion of 23 M/Y

as per ETKA
Production change
All vehicles from SCBCZ13S8MC090690 are to specification, in the event the described issue is evident post the suggested VIN, please raise a
DISS query and await feedback before conducting any further work
Measure
1) If not already done, raise a DISS query.
2) Check “Low fuel pressure, specified value” and “Fuel low pressure, actual value” within the fault memory, refer to ECU “01 –
Engine Control Module 1” - From “ Extended ambient conditions” note the values of the “Low fuel pressure, specified value” and
“Fuel low pressure, actual value ” – Figure 1.
INTERNAL
Figure 1
•
If not already done, raise a DISS query, add the following results / information.
Note the “Low fuel pressure, specified value” and “Fuel low pressure, actual value” on the DISS query.
•
Using ODIS Measured values check low fuel pressure when the vehicle is starting or idling – this should normally be 400 – 800 kPa.
•
Check the fuel system pressure at the fuel tank outlet with a pressure gauge, this should be the same as the figure measured with ODIS or
approximately 100 kPa lower if the gauge is relative to atmospheric pressure.
•
After switching the engine off the pressure within the fuel system should remain at 400 kPa or above for at least ten minutes.
•
Check the fuel pump ECU electrical earth point condition, check for debris, cleanliness and tightness of earth point nut - if any issues were
found - Rectify as required
•
Record results on the DISS query, attach clear photograph(s).
•
Check all fuel pump ECU connector pins for signs of contamination or damage. Check for any other concern that may lead to poor
retention, high resistance or poor connection. Ensure issues noted during this inspection are corrected
3) Fit a new fuel pump control module with the part number of 4M0906093L - Or latest specification available part as per ETKA
•
Clear any fault codes that may be present and conduct a short road test, make a note of any fault codes that are logged during the road
test
•
Should any issues be evident from any previous technical checks/inspection or for example:
DTC’s logged during the road test
The issue can be reproduced
Repeat visit for the same issue
Fuel level shown in the DIP does match the actual amount of fuel which is in the tank (as applicable MWB’s)
•
The Operative MUST add any relevant information to the DISS query
Or
•
Should no issues be evident, the car can be returned to the customer
