"Voluntary Emissions Recall Campaign 11E-A03: Replace the SCR Mixer. The Selective Catalyst Reduction (SCR) mixer has also been improved to optimize the Diesel Exhaust Fluid (DEF) mixture when introduced into the exhaust system. AFFECTED VEHICLES This Emissions Recall Campaign involves X5d and 335d models that were produced from February 2010 to September 2010. 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."
