If pronounced these deposits can lead to spark plug fouling, cylinder leakage and fouled injectors all influencing combustion in the cylinder. As a result the above event entries are logged in the engine control unit Production change None Measure 1. Follow the Misfire best practice TPI 2051187 in order to confirm that the root cause of the misfire is excessive cylinder carbonisation leading to excessive cylinder leakage/fouling. 2. Raise a DISS query with your findings, this action is an essential element of the investigation 3. Ensure cylinder compressions are tested and recorded, this action is an essential element of the investigation 4. Ensure cylinder leakage is checked and recorded, this action is an essential element of the investigation 5. From two of the cylinders that have recorded misfires take borescope images of each inlet valve stem 6. Note: The following operations should only be carried out if excessive carbonisation is confirmed 7. Check and if necessary correct all engine and transmission fluid levels 8. Fill fuel tank 9. Add the relevant dose of G17 Fuel additive to the fuel load as specified on the bottle (refer to ETKA) 10. 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 11. Repeat operations 3 through 5 and compare results if improvement is noted repair is complete 12. If no or little improvement is recorded then the condition of the spark plugs and low pressure injectors will need to be confirmed and replaced where necessary 13. If this repair procedure is not successful report back via DISS query 14. On successful completion check and if required drain any excess oil from the intercoolers reference TPI 2050222 15. Before returning vehicle to customer top up to fill the fuel tank Warranty accounting instructions To carry out the Injector cleaning process (points 8-10) Warranty type 110 or 910 Labour operation code 24 40 29 00 Damage Service Number 24 40 Damage Code 00 10 Time 20 TU Refer to ElsaPro for all other labour operation times INTERNAL Parts information Part number Description Refer to ETKA Additive INTERNAL Quantity As required
