M0349 SCR Replacement, 13L VGT and TC Engine
VAH, VHD, VN
RECALL INFORMATION
(April 2025)
Volvo Trucks has identified that the Selective Catalyst Reduction (SCR) system in certain vehicles
equipped with the MY 2017 or 2018 13L VGT and Turbo Compound (TC) 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.
To ensure Volvo remains emission compliant on these vehicles, follow the repair instructions outlined in
this document to replace the Selective Catalyst Reduction (SCR) system with new one.

VEHICLES AFFECTED
Certain Volvo vehicles manufactured between November 31, 2016, and December 21, 2018.
