| 2069806/2 | 2023-09-07. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY; ELECTRICAL SYSTEM. HVAC refrigerant leakage suspected Or reports of a damp/musty smell within the cabin - Diagnosis guidelines. Customer statement / workshop findings: HVAC not cooling / HVAC cooling less than expected / HVAC refrigerant leakage confirmed Or The customer reports a damp/musty smell within the cabin Note: For this scenario please see the pre requisites below - Should no HVAC leak be evident and a damp/musty smell has been reported/identified the operative should first confirm that water is not leaking into the cabin please refer to all VIN applicable TPIs particularly TPI 2062622/- - Should there be no water leaks evident, the operative should check the HVAC and body drains for blockages, in the event the drains are blocked the drains must be unblocked, once this has been completed the operative should confirm if the damp/musty smell is still evident. In the event that HVAC cleaning products are required, these MUST be sourced locally. Before using the cleaner the operative must inform the customer of the product which will be used, a neutral fragrance cleaner should be used as the customer may not like the smell of the cleaner should a fragranced product be used Please ensure all supporting information is included within the DISS query when requesting permission to clean the HVAC system including clear photographs and/or videos showing the reported issue, should the required information not be supplied the warranty claim could be cancelled. |
| 2071131/1 | 2023-09-07. Service bulletin. ELECTRICAL SYSTEM. Measured values - Cycle recording instructions.

| 2070998/1 | 2023-08-03. Service bulletin. SEAT BELTS; ELECTRICAL SYSTEM. Rear seatbelt - Incorrect buckle status within the DIP - Bentayga Series. Customer statement: Incorrect rear seatbelt buckle status shown within the DIP Workshop findings: Although there is no occupant evident within the rear seats (2nd row) the rear seat is shown as occupied (Figure 1). Technical background: There is no specific DTC evident for the scenario described. The issue described is evident as the rear seat belt buckles are not resistor coded The system uses a non-resistor coded buckle strategy (zero-infinity or open-closed buckle) for the rear seats. In correct operation, a fastened seatbelt is open circuit and an un-fastened seatbelt is closed circuit If harness damage is present or an electrical connector joint is not properly engaged, an unintended open circuit occurs. This will give an incorrect buckle status reading within the DIP The advice within this TPI should be referred to first before conducting any further diagnosis or disassembly of the vehicles interior Previous assembly/disassembly may have caused an unintentional open circuit when operatives have been working on or around the rear seat belt assemblies |
