Volvo Trucks is rolling out an updated diesel exhaust fluid (DEF) inducement software across its fleet, impacting both new and existing models. This move, aligning with the latest U.S. Environmental Protection Agency (EPA) guidelines, aims to enhance operational uptime for users.
What Happened
Volvo Trucks' latest software update targets DEF systems, a critical component in reducing nitrogen oxide emissions through Selective Catalytic Reduction (SCR). Announced for all new trucks and progressively being integrated into existing models, the update extends the repair window from 4 hours to 160 hours and increases final inducement speeds from 5 mph to 25 mph. This shift is significant for fleets relying on Volvo’s D13 VGT and D13 TC engines, as all new VNL and VNR trucks manufactured since May 2026 already feature this upgrade. The company plans to complete the rollout for all eligible post-2010 model year vehicles by the end of 2027.
What This Means for Your Business
For fleet operators and business decision-makers in the AECM sector, this software update represents a strategic advantage. By extending the time available to address DEF-related issues, operators can minimize unexpected downtime and maintain productivity. The ability to remotely update software for Legacy Model Year 2024 and newer vehicles by the end of summer further underscores Volvo’s commitment to seamless compliance and operational efficiency. Businesses can anticipate reduced maintenance costs and improved ROI due to increased vehicle uptime and fewer service disruptions.
What US Operators Should Watch
Operators should track the rollout timeline closely, particularly the availability of remote software updates for eligible models by summer’s end. Additionally, attention should be given to the gradual expansion to all post-2014 model year vehicles by Q2 2027 and the entire eligible fleet by the end of 2027. For vehicles lacking remote update capabilities, scheduling dealership visits for software upgrades will be essential.
