Bulletin Summary
Following WB13-04, update the hot gas pickup tube circuit for an improved version with a better resistance to vibrations. This bulletin resolves A/C Low Pressure messages in the dashboard when the auxiliary fan is not running. The valve will open at a set low pressure to return hot gas in the low pressure circuit until the required pressure is reached, thus preventing the occurrence of low pressure events in the above conditions.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
