Turbocharger speed sensor DTC's stored Transaction No.: 2053348/9 Release date: 09-Nov-2022 Customer statement / workshop findings Customer statement: • Engine management light is evident within the DIP Workshop findings: • Engine management light is evident within the DIP DTC P259400 - Turbocharger Speed Sensor “B” - Circuit Range/Performance are stored within address 01 - Engine Control Module 1 or address 11 - Engine Control Module 2 could be evident with the following symptom codes • 23179 (only) Or • 23179 with 32790 Or • 32790 (only) Or One or a combination of the following DTC’s may also be evident (with no specific symptom codes) • P259500: Turbocharger Speed Sensor “B” - Circuit low • P259600: Turbocharger Speed Sensor "B" - Circuit High • P257900: Turbocharger Speed Sensor “A” - Circuit Range/Performance Technical background Refer to the instructions within the Measure section of this TPI ensuring the correct method of repair is followed depending on the DTC and symptom code Revision history 2053348/6 • Additional DTC’s/symptom codes added within the Measure section 2053348/7 • Warranty accounting instructions are now included • Measure section amended to include detail regarding the requirement to raise a Technical DISS query (depending on symptom) Production change Not applicable Measure The operative should lease with the customer to clarify the driving conditions in which the issue occurs, see examples below: • Duration the vehicle was driven before the issue was evident • Throttle load (harsh or light acceleration) • What gradient they were driving on (uphill/downhill/flat road surface etc) • Speed of the vehicle when the issue occurred • Road conditions for example: City driving with traffic queues Comments INTERNAL IMPORTANT: The operative should include the customer feedback to a new or existing Technical DISS query P259400: Turbocharger Speed Sensor “B” – Circuit Range/Performance with the following symptom codes • 23179 (only) Or • 23179 and 32790 Or • 32790 (only) NOTE: Step 1 only applies to New Continental GT/GTC and New Flying Spur 1) Referring to Rep.Gr 24 - Remove the air filter top cover New Continental GT/GTC and New Flying Spur Only • Inspect for damage or missing components NOTE: The example in Figure 1 shows an air filter box divider that has become detached, causing DTC - P259400: Turbocharger Speed Sensor “B” - Circuit Range/Performance • Reattach the divider and retest the vehicle if this particular fault is found Figure 1 • Should no issues be found within the air filter box please continue with the remaining instructions from step 2 2) All Models Road test the vehicle to attempt to reproduce the complaint TIP: Carry out an extensive road test if required IMPORTANT: Drive the vehicle under the same driving conditions as when the customer experienced the complaint, using light and hard acceleration cycles 3) Referring to Rep.Gr 24 - Air/vacuum system - Leak diagnostic process using smoke machine - Check the intake and exhaust systems for air leaks NOTE: If a leak is detected the operative should feedback the findings via a new or existing Technical DISS query, once a response is received the operative should rectify the leak as required 4) Carry out all applicable test plans for the affected Turbocharger speed sensor, if wiring checks are suggested the operative must also carry out the following manual wiring checks for the affected sensor: • Open circuit • Short circuit to ground INTERNAL • Short circuit to B+ • Short circuit of the wires to each other If the wiring tests are to specification refer to the information as below depending on the DTC which is evident: P259400: Turbocharger Speed Sensor "B" Circuit Range/Performance with symptom code 23179 (only) Question: Is this the first complaint received regarding P259400 with symptom code 23719? NO - Raise a new or respond via the existing Technical DISS query HINT: To assist with further diagnosis the operative must include all required information, including • Current ODIS log • Include all relevant information relating to the failure mode • Photographs or videos of any issues found YES - Clear the applicable DTC and retest to confirm if the issue has been rectified (Parts replacement not required). If issue repeats, raise a new or respond via existing Technical DISS query IMPORTANT: Drive the vehicle under the same driving conditions as when the customer experienced the complaint, using light and hard acceleration cycles NOTE: Should any of the following DTC’s and symptom codes be evident Referring to Rep.Gr 21 - Replace the applicable Turbocharger speed sensor HINT: Please ensure that the instructions within the applicable Rep.Gr are strictly followed including the replacement of any single use items NOTE: Please also ensure that for Betayga models the alignment of applicable driver assist systems is conducted including four wheel alignment (Depending on vehicle specification) • P259400: Turbocharger Speed Sensor "B" Circuit Range/Performance with symptom code 23179 and 32790 • P259400: Turbocharger Speed Sensor "B" Circuit Range/Performance with symptom code 32790 (only) • P259500: Turbocharger Speed Sensor "B" Circuit Low • P259600: Turbocharger Speed Sensor "B" Circuit High • P257900: Turbocharger Speed Sensor "A" Circuit Range/Performance IMPORTANT: In the event the issue is still evident after replacing the applicable Turbocharger speed sensor, the operative should raise a new or respond via the existing Technical DISS query and await feedback before conducting any further work When replacing the Turbocharger speed sensor take extreme care not to damage the component, DO NOT discard of the sensor as it may be requested back for analysis IMPORTANT: Please ensure the new or existing Technical DISS query detailing the method of repair is submitted Warranty accounting instructions Warranty type 110 or 910 Damage service number 21 59 Damage code 00 40 Bentayga Time to replace Bank 1 Turbocharger speed sensor (G688) Labour operation code 21 59 19 02 Time 960 TU’s Time to replace Bank 2 Turbocharger speed sensor (G689) Labour operation code 21 59 19 01 Time 540 TU’s Alignment of applicable driver assist systems (Depending on vehicle specification) • Vehicle front + rear measured wheel alignment checked - 44 95 03 00 - 110 TU INTERNAL • Rear wheel camber adjust - 44 94 15 50 - 30 TU • Rear wheel track adjust - 44 93 15 50 - 30 TU • Front wheel camber adjust - 44 89 15 50 - 40 TU • • Front wheel track adjust - 44 88 15 50 - 20 TU (ACC) - Radar sensor checked + adjusted - 91 63 05 51 - 30 TU • Overhead view camera adjusted - 90 83 15 00 - 40 TU • Driver assist camera adjusted - 96 38 15 50 - 120 TU • Control unit for (Lane change assist) adjusted - 96 35 15 00 - 50 TU • Night vision system calibration - 90 80 15 50 - 40 TU • Headlamps to adjust - 94 15 16 00 20 TU New Continental GT/GTC and New Flying Spur Time to conduct air filter box check Labour operation code 24 24 01 00 (Use 99 index until 29/09/22) Time 10 TU’s Time to replace Bank 1 Turbocharger speed sensor (G688) Labour operation code 21 59 19 02 Time 160 TU’s Time to replace Bank 2 Turbocharger speed sensor (G689) Labour operation code 21 59 19 01 Time 160 TU’s All Models Road test Labour operation code 01 21 00 00 Time 50 TU’s Wiring integrity checks Labour operation code 97 09 01 00 Time Must not exceed 50 TU’s Parts information Refer to the ETKA parts catalogue INTERNAL
