Service bulletins for the 2021 Bentley Continental
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.

| 2061369/3 | 2021-10-06. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Engine overheating -Warning on theDIP-V8Kovomo 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 from the coolant pump is interrupted in the warm-up phase by the solenoid valve 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 |

Carry out the checks within the Measure section of this TPI noting the following: The steps within the Measure section are applicable to vehicles specified with or without the Otto Particulate Filter (OPF) also referred to as the Gasoline Particulate Filter (GPF) NOTE: OPF/GPF fitment is Region specific. Should any issues be evident and the vehicle is specified with (OPF/GPF) The operative should check to confirm if EB89 (SC21/08 is required) and conduct if applicable. In the event that EB89 (SC21/08)is not required and the symptoms described within this TPI are evident the onward instructions should be followed. |
| 2060596/3 | 2021-10-06. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING. Transmission DTC - U040100 50273/C461 Invalid Data Received From ECM/PCM "A" Customer statement / workshop findings: Diagnostic Trouble Code (DTC) U040100 50273/C461 Invalid Data Received From ECM/PCM "A" stored within the Transmission Control Unit. Technical background: During Adaptive Cruise Control (ACC) brake to stop events, it is possible for the brake pressure to decay at a rate outside of specified parameters, DTC - U040100 50273/C461 Invalid Data Received From ECM/PCM "A" will therefore be stored within the Transmission Control Unit. |
| 2050334/7 | 2021-10-05. Service bulletin. ENGINE AND ENGINE COOLING. Ticking noise from engine bay. Customer statement / workshop findings: Ticking noise emanating from rear of Bank 1 cylinder head Technical background: Noise from failed vacuum pump. Measure: A specific vacuum pump failure is known to create a ticking noise. This ticking noise, on initial inspection, is easily misinterpreted as a fault in the valve train or fuel injector, when in reality it is more likely to be produced by a defective vacuum pump. Therefore always ensure that this type of noise is identified precisely using a stethoscope. Specifically use the stethoscope to check the vacuum pump located at the rear of Bank 1 cylinder head, when this is found to be the origin of the noise then change the vacuum pump and retest. |
| 2049586/8 | 2021-10-05. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Misfiring, W12 TSI - Excessive carbon build up cylinder leakage. Customer statement / workshop findings: Customer statement: Emission control warning signal displayed, engine misfire Workshop findings: Event entries in engine control unit relating to cylinder misfires excessive carbon build up to leading to cylinder leakage and spark plug foul. Technical background: Deviations in the country-specific fuel specifications can lead to carbon deposits on the injectors. 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. Measure: - 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 |
