Service bulletins for the 2021 Bentley Flying Spur

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Diagnostic Trouble Codes (DTC) P052400: Engine Oil Pressure Too Low and/or P15AA00: Engine oil pressure - Lower limit not reached stored in the Master Engine Control Unit (ECU) Measure: VERY IMPORTANT: Prior to conducting the onward instructions, the following symptoms MUST be evident - Warning on Driver Instrument Panel (DIP) Oil pressure too low And/or - Diagnostic Trouble Codes (DTC) P052400: Engine Oil Pressure Too Low and/or P15AA00: Engine oil pressure - Lower limit not reached stored in the Master Engine Control Unit (ECU) Should any of the afore mentioned not be evident and the symptoms cannot be reproduced No further action should be taken unless the issue can be reproduced or demonstrated by the customer
2061362/12020-12-05. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Engine intermittently fails to start. Customer statement: Customer unable to intermittently start the engine with the start button. Workshop findings: DTC - B143C29: Access/start authorization button, Range/Performance stored within address 46 -Convenience system central control unit Technical background: Refer to the Measure section of this TPI
2061369/12020-12-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Engine overheating - Warning on the DIP - V8 Kovomo. Customer statement / workshop findings: -Customer reports an engine overheat warning on the DIP -Engine overheats -Unusual cooling fan operation at high temperatures -There are no signs of coolant leaks both internally or externally Technical background: To heat the engine as quickly as possible during cold starting, delivery of coolant by the coolant pump is interrupted in the warm-up phase by the solenoid for the mechanical coolant pump. The solenoid is designed to cut off the vacuum supply to the coolant pump when the engine reaches the maximum temperature, the vacuum cut off allows the engine to start circulating coolant by retracting a sleeve which is situated around the coolant pump impeller. When the solenoid is at fault (sticking open) the vacuum supply is constant, this allows the sleeve to stay in position around the impellor which leads to the symptoms described within the Customer statement/Workshop findings section of this TPI.
2061064/12020-11-07. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Secondary air injection - Missing ODIS data. Customer statement / workshop findings: Not all data for the secondary air injection operation is available when using ODIS Technical background: Data is only available for four of the eight secondary air monitors on each cylinder bank therefore some test plans and related tasks are not currently available
2053170/62020-11-05. Service bulletin. POWER TRAIN; EQUIPMENT; ENGINE; ELECTRICAL SYSTEM. Gear shift optimisation procedure - W12 TSI only. Customer statement / workshop findings: Customer reporting dissatisfaction with transmission shift quality in various driving conditions Prior to starting the instructions within this TPI, the Retailer must check and confirm the vehicle is in standard factory condition and has not had any non- approved aftermarket modifications conducted including the modification of the engine control modules ( chip tuning) Should any aftermarket modifications be found, the Retailer must make Product Support aware by raising a DISS query to report the details of the modification, you must then await feedback from Product Support before conducting any further repairs relating to the shift quality complaint Technical background: IMPORTANT: To allow the engine and transmission to adapt to the customers driving style the vehicle MUST either have covered at least 1000 miles/1600 Km or must have been used over a six week period (which ever occurs first) before carrying out the instructions within this TPI
2053351/62020-11-03. Service bulletin. ENGINE AND ENGINE COOLING. Buzzing noise from engine area. Customer statement / workshop findings Workshop findings: Buzzing noise heard at idle from the sump area when the vehicle is elevated on a workshop ramp. The noise cannot be heard from inside the cabin or outside of the vehicle in normal circumstances. Technical background: A buzzing noise can be generated by the oil pump when the engine is running at idle.
2058423/42020-11-03. Service bulletin. EQUIPMENT; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. New Continental GT/GTC, New Flying Spur and Bentayga Speed - Low Oil Pressure Warning During Early Vehicle Life Customer statement/workshop findings: Warning on the Driver Instrument Panel (DIP) - Oil pressure too low DTCs relating to oil pressure may also be stored within the Master ECU. Diagnostic Trouble Codes (DTC) P052400: Engine Oil Pressure Too Low and/or P15AA00: Engine oil pressure -Lower limit not reached stored in the Master Engine Control Unit (ECU) Technical background: CAUTION: DO NOT CONTINUE WITH THIS DOCUMENT IF THE ENGINE EXHIBITS ANY ABNORMAL MECHANICAL NOISE OR HAS AN ENGINE LUBRICATING OIL LEAK SEEK FURTHER ADVICE THROUGH A NEW OR EXISTING DISS QUERY
2057978/42020-11-03. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT. Engine Lubricating Oil - Replenishment. Customer statement / workshop findings: Engine lubricating oil lamp illuminated on driver instrument panel. Engine lubricating oil requires topping up between services. Technical background: In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified running-in periods consume more oil during the running-in period, and the oil consumption will stabilize after the running-in period. Refer to the Owners Manual for specific running-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, ambient temperature and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue, and the oxidation level of the oil. Certain driving conditions may negatively influence the rate of oil consumption. This can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods.
2028808/42020-08-05. Service bulletin. ENGINE AND ENGINE COOLING. Engine oil. Specific oil type and oil consumption reference. Customer statement / workshop findings: Engine oil level requires to:p up between services. Technical background The use of the correct oil for each engine type is critical for its continued performance, reliability and ultimately warranty. The workshop manual should always be the first point of reference, ensuring the correct lubricant is used for each specific model year and engine type Should oil be required the parts catalogue must be referred to ensuring the correct VIN is always used when ordering
