Service bulletins for the 2012 Bentley Mulsanne

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.

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.

2033282/22020-01-17. Service bulletin. ELECTRICAL SYSTEM; STRUCTURE; VISIBILITY. Mulsanne exterior door mirror software update (SC13/03) Technical background: Bentley Motors has devised a Software Version Management (SVM) update which eliminates the possibility of a customer experiencing issues relating to the exterior door mirror power fold/unfold operation. The containment measure within the SVM update reduces mirror motor cut off time which prevents the door mirrors sticking and jolting sporadically during the power fold/unfold operation. The SVM update also prevents the possibility of a separate mirror related issue from occurring, the issue concerned can occur when the Fold mirrors function is selected to be On within the MMI as shown in Figure 1. Selecting this function allows the mirrors to be power folded when the vehicle is locked. Remedy: This Campaign must be carried out on all Mulsanne cars within the affected VIN range to ensure the cars prior to the VIN cut off are all at the same software level
