Ask the customer if the vehicle has been modified or updated in any way including non approved software modifications to the engine control unit(s) Ensure the customer is using the correct minimum fuel octane rating (refer to fuel filler flap label for the minimum grade in your region). Check the customer is using the correct engine lubrication oil type if and when topping up, and if advised on the service schedule is using G17 fuel additive Check the vehicle service history, pay particular attention to recent work that may potentially cause poor engine running or a misfire Conduct a vehicle diagnostic check, note all Diagnostic Trouble Codes (DTC) present. Check if the vehicle is currently exhibiting the reported concern, a road test may be required to confirm. If a misfire or poor engine running is evident DO NOT test drive the vehicle Please record as much information as possible including the driving style and environmental conditions up to and at the time of the failure, this may be required if a DISS query is raised If no relevant fault codes are stored and poor engine running or a misfire is not present ask the Customer to demonstrate the concern, if the concern cannot be replicated do not continue with this TPI, explain to the customer that since the concern is not present and fault codes are not stored it is not possible to carry out any diagnosis or repair If fault codes are stored but poor engine running or misfire is not present continue to section 2 only, ask the Customer to demonstrate the concern. If the concern cannot be recreated and no issue is detected during the visual check or road test do not continue with this TPI, explain to the customer that since the concern is not present it is not possible to carry out any diagnosis or repair, explain what analysis has actually been carried out If the Customer complains for a second separate instance of poor engine running or misfire and a relevant fault code is present but the vehicle does not have poor engine running or misfire continue to work through this document, during Section 3 - Analysis / Component Substitution it is only possible to conduct a visual inspection of any removed component, it would not be advisable to exchange components unless poor running or a misfire is actually present INTERNAL Section 2 - Initial Visual Checks Complete a “Battery Condition Check” Refer to Rep.Gr 27 Conduct a visual check within the engine bay, engine covers should be removed to allow a thorough inspection. If visible, pay particular attention to the condition of Ignition Coils, Fuel Injectors, Electrical Connectors and Wiring loom condition, do not remove any additional parts at this stage unless an issue is observed and further analysis is required Check vehicle fluid levels, including - fuel, engine lubricating oil, engine coolant, look for signs of contamination or leaks Any observations that may be the cause of poor engine running / misfire should be investigated and corrected at this point Section 3 - Analysis / Component Substitution Considering the information gathered within sections 1 and 2, carry out a controlled component substitution for any specific cylinders that exhibit a concern, for example - if there is a fault code for cylinder five misfire exchange cylinder five Ignition coil with an ignition coil from another cylinder, check to see if the fault moves with the ignition coil. It is recommended to move only one component at any one time usually starting with the easiest component to change, for example move ignition coil first, then sparking plug and finally fuel injectors If components are removed and show signs of significant carbon deposit or oil contamination please continue to section 4 - Figure 1 Figure 1 Section 4 – Raise a DISS Query After completing sections 1, 2 and 3 if the root cause of the poor engine running / misfire has not been identified continue to raise a DISS query. Images accompanying a DISS query must be of a quality shown in Figures 2 and 3 Figure 2 INTERNAL Figure 3 Warranty accounting instructions Warranty type - 110 or 910 Damage service numbers • Injectors: 24 40 • Ignition Coils: 28 20 • Spark Plugs: 28 70 Damage code 00 55 Labour Operation times Section 1 - Vehicle history and current status (all models) 06 89 00 00 - Review History (Vehicle preparation) - 20 TU 01 29 00 03 - Self-diagnosis - 30 TU 01 21 00 00 – Road test - 50 TU Section 2 - Initial visual checks (all models) 27 06 01 00 - Battery Health Check - 10 TU Section 3 - Analysis / component substitution W12 Engine Derivative 12 fuel injectors remove and refit Low pressure: 24 41 19 00: Fuel rail remove + reinstall - 170 TU 24 40 20 50: Injectors remove + reinstall x12 - 80 TU New GT/C 24 40 20 50: Injectors remove + reinstall x12 - 50 TU Bentayga and New Flying Spur 24 40 19 50: Injector remove + reinstall x1 - 10 TU (low pressure) High pressure: 24 41 19 03: Fuel rail remove + reinstall - 340 TU - Bentayga 24 41 19 01: Fuel rail remove + reinstall - 430 TU - New GT/C and New Flying Spur INTERNAL 24 40 20 53 - Injectors remove + reinstall x12 - 60- TU - Bentayga 24 40 20 51: Injectors remove + reinstall x12 - 340 TU - New GT/C 24 40 20 51: Injectors remove + reinstall x12 - 100 TU - New Flying Spur 24 40 19 53: Injector remove + reinstall x1 - 10 TU - All models Spark plugs remove and refit 28 70 20 00: Sparking plugs remove + reinstall x12 - 200 TU (Bank 1+2) 28 70 19 00: Sparking plug remove + reinstall x1 - 90 TU (Bank 1) 28 70 19 01: Sparking plug remove + reinstall x1 - 20 TU (Bank 2) Ignition coils remove and refit 28 20 20 00: Ignition coils remove + reinstall x12 - 170 TU (Bank 1+2) 28 20 19 00: Ignition coil remove + reinstall x1 - 80 TU (Bank 1) 28 20 19 01: Ignition coil remove + reinstall x1- 10 TU (Bank 2) V8 Engine Derivative 4.0 Litre V8 Fuel injectors remove and refit - x8 24 40 20 70: Injectors remove + reinstall x8 - 120 TU (Bank 1+2) Fuel injectors remove and refit - x4 24 40 20 72: Injectors remove + reinstall x4 - 70 TU (Bank 1) 24 40 20 71: Injectors remove + reinstall x4 - 50 TU (Bank 2) 24 41 19 22: Fuel rail remove + reinstall - 440 TU (Bank 1) 24 41 19 21: Fuel rail remove + reinstall - 210 TU (Bank 2) Sparking plugs remove and refit 28 70 20 20: Sparking plugs remove + reinstall x8 - 270 TU (Bank 1+2) 28 70 20 22: Sparking plugs remove + reinstall x4 - 150 TU (Bank 1) 28 70 20 21: Sparking plugs remove + reinstall x4 - 170 TU (Bank 2) Ignition coils remove and refit 28 20 20 20: Ignition coils remove + reinstall x8 - 230 TU (Bank 1+2) 28 20 20 22: Ignition coils remove + reinstall x4 - 140 TU (Bank 1) 28 20 20 21: Ignition coils remove + reinstall x4 - 160 TU (Bank 2) 6.75 Litre V8 Fuel injectors remove and refit - x8 24 40 20 00: Injectors remove + reinstall x8 - 410 TU (Bank 1+2) Fuel injectors remove and refit - x4 24 40 20 01: 4 Injectors remove + reinstall - 270 TU (Bank 2) 24 40 20 02: 4 Injectors remove + reinstall - 230 TU (Bank 1) Sparking plugs remove and refit - x8 28 70 20 00: 8 Sparking plugs remove + reinstall - 160 TU (Bank 1+2) INTERNAL Ignition coils remove and refit x8 28 20 20 20: 8 Ignition coils - remove + reinstall - 230 TU (Bank 1+2) V6 Engine Derivative Fuel injectors remove and refit x6 24 41 20 30: Fuel rail remove + reinstall - 250 TU (Bank 1+2) 24 40 20 80: Injectors remove + reinstall 6 off - 50 TU (Bank 1+2) Fuel injectors remove and refit x3 24 41 19 32: Fuel rail remove + reinstall - 140 TU (Bank 1) 24 40 20 82: Injectors remove + reinstall x3 - 30 TU (Bank 1) Or 24 41 19 31: Fuel rail remove + reinstall - 140 TU (Bank 2) 24 40 20 81: Injectors remove + reinstall x3 - 30 TU (Bank 2) Spark plugs remove and refit 28 70 20 30: Sparking plugs remove + reinstall x6 - 170 TU (Bank 1+2) 28 70 20 32: Sparking plugs remove + reinstall x 3 - 100 TU (Bank 1) 28 70 20 31: Sparking plugs remove + reinstall x3 - 110 TU (Bank 2) Ignition coils remove and refit 28 20 20 30: Ignition coils remove + reinstall x6 - 150 TU (Bank 1+2) 28 20 20 32: Ignition coils remove + reinstall x3 - 90 TU (Bank 1) 28 20 20 31: Ignition coils remove + reinstall x3 - 110 TU (Bank 2) INTERNAL
