Bulletin Summary
Volvo Trucks has identified that the Selective Catalyst Reduction (SCR) system in certain vehicles equipped with the MY 2017 or 2018 (13L VGT) engine are not meeting California and EPA emissions standards, or Volvo cannot confirm its compliance. These vehicles have been flagged due to telematics data showing that the NOx conversion efficiency of the SCR system has dropped below 94% for eight weeks. Alternatively, these vehicles may have communication issues with telematics, such as not reporting or ceasing reporting for the same period.
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.
