Service bulletin 180212

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.

NHTSA's summary

"?Voluntary Emissions Recall Campaign 11E-A03: Check and/or Replace Emissions Monitoring Components. 1. The Selective Catalyst Reduction (SCR) catalyst has been improved to increase emissions stability over the service life of the vehicle. 2. The SCR mixer has also been improved to optimize the Diesel Exhaust Fluid (DEF) mixture when introduced into the exhaust system. 3. Under certain driving conditions, the High-Pressure (HP) EGR valve may become restricted with excessive soot. This restriction impedes the emissions performance of the HP EGR valve. This situation may lead to the Service Engine Soon lamp illuminating. An optimized EGR valve has been developed to limit this soot buildup. Note: These improved parts may have already been replaced during a previous service visit. It will be necessary to inspect these components first before replacement. 4. Reprogramming of the DDE to optimize these improved emissions monitoring components. AFFECTED VEHICLES This Emissions Recall Campaign involves X5d and 335d models that were produced from January 2008 to September 2009. In order to determine whether a specific vehicle has had this Emissions Recall Campaign completed or is affected by this Emissions Recall Campaign, first check if the ""Emissions Recall Campaign Completed"" label SD 92-435 is attached to the right (passenger) rear side of the hood in the engine compartment, close to the windshield. If the label is found, the campaign has already been performed. If the ""Emissions Recall Campaign Completed"" label is not present, it will be necessary to utilize the ""Service Menu"" of DCSnet (Dealer Communication System) or the Key Reader. Based on the response of the system, either proceed with the corrective action or take no further action. If the label is found, the campaign has already been performed. If the ""Emissions Recall Campaign Completed"" label is not present, it will be necessary to utilize the ""Service Menu"" of DCSnet (Dealer Communication System) or

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
