Bulletin Summary
Concerns: Vacuum pump Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that the elastomer check valve in the additional outlet on the vacuum pump can become damaged over the service life of the vehicle. As a result, the vacuumsupplied to the secondary loadsmay not be sufficient. This can cause malfunctions in the variable intake system. The lack of vacuum can also result in a fault entry during tank leakage diagnosis in the DME and can cause the Check Engine light to come on.
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.
