When DTC’s relating to cylinder misfire/s are stored in address 01-engine control module 1 or address 11-engine control module 2,
the Misfire best practice TPI 2051187 must be followed. If the cause of the misfire is diagnosed as a blocked low pressure fuel
injector, additional work is also required as per the instructions within the measure section of this TPI
Technical background
Debris in the fuel system can lead to a blockage in the low pressure fuel injectors, ultimately causing a cylinder misfire.
Production change
All VIN’s post VIN SCBBE53S5LC082494 should not exhibit the symptoms described, in the event the symptoms described are evident and the
VIN is after the cut off please raise a DISS query and await feedback before conducting any further work
Measure
VERY IMPORTANT: Before conducting the instructions within the Measure section the operative MUST be aware and adhere to Rep.Gr
20
•
Fuel system - Safety precautions
•
Fuel system - Rules for cleanliness
When an engine misfire is apparent and/or the Engine management light is on with generic misfire DTC’s stored, the Misfire best practice TPI
2051187 must be followed. If the final diagnosis is a blocked low pressure fuel injector/s then follow the onward instructions;
1. Erase any DTC’s stored.
2. Fill fuel tank
INTERNAL
3. Add the relevant dose of G17 Fuel additive to the fuel load as specified on the bottle (refer to ETKA)
4. Run the engine at idle for 8 hours – Periodically check to ensure engine coolant temperature is within safe limits – do not allow engine to
overheat
5. Recheck event memories and erase any DTC’s stored.
6. Retest for the customer complaint (road test where necessary), if the complaint is rectified no further action is required.
If the complaint is still evident then follow the onward instructions from Step 7
7. Referring to Rep.Gr 20 - Low pressure fuel system - To test - Conduct the process to completion
On completion of the Low pressure fuel system test - With the pressure gauge still attached to vehicle perform the following check:
•
Ensure the engine is switched off
•
Monitor the fuel pressure at 5 minutes of engine switch off and 10 minutes of engine switch off
HINT: If the pressure drop is considered a high rate of pressure decay (>1 bar) perform an inspection of the fuel lines (working from the engine
rearwards towards the fuel tank checking for the following:
•
Damage
•
Kinking of the fuel lines
•
Leakage
8. Should no issues be found - Refer to Rep.Gr 20 - Gain access to the Fuel pump within the fuel tank
•
Inspect the Fuel supply module and fuel filter fitment for detached hoses, damaged hoses and line and/or concerns with the module itself
such as damage or leakage
•
Figure 1 shows an example of a fuel tank internal hose with pin holes (circled)

•
Figure 2 shows a close up of the pin holes

9. Should any of the afore mentioned issues be evident the required parts should be replace as necessary
However in the event that all previous checks were to specification the operative should conduct step 10 to completion
10. Replace both bank 1 and 2 low pressure fuel rails, the fuel rails come complete with injectors (Figure 3).
