Mobile DPF Regeneration & Emissions
DPF Light On? Don’t Call a Tow. Call Us.
On-Site Forced Regens and Emissions Diagnostics
A loaded diesel particulate filter can push a truck into derate or shut it down mid-route. Our mobile technicians run forced regens and full emissions diagnostics in your yard or at the roadside, so the truck gets back to work without a tow or a shop visit.
DPF and Emissions Services
Clear the Filter. Find the Cause.
Forced DPF Regeneration
A parked regen run on-site to burn off soot and restore full power.
Managed DPF Regeneration (PM-C)
Scheduled regens built into PM-C service, so filters are cleaned before they become a problem.
Emissions System Diagnostics
Root-cause diagnosis of sensors, DEF dosing, EGR and wiring, not just clearing the code.
ECM / TCM Diagnostic Health Scans
Early detection of emissions and powertrain faults during scheduled service.
Fault-Code Monitoring (Tier 3)
Live Samsara and Geotab monitoring flags DPF and emissions codes before the light reaches the driver.
Documented Work
Every job recorded with photos and video in your Fullbay fleet portal.
Why Filters Clog
Stop-and-Go Freight Is Hard on Filters
Highway miles let a DPF clean itself. Local delivery routes, yard moves, long idle times and Chicago winters don’t. Exhaust never gets hot enough for a passive regen to finish, soot builds up and the truck eventually derates.

DPF Service FAQ
DPF and Emissions Questions
Which engines do you work on?
We perform forced DPF regenerations and emissions diagnostics on Cummins, Detroit, PACCAR and Volvo engines.
Can you do a DPF regen on the roadside?
Yes. Our mobile units can regen wherever the truck is safely stopped, whether that’s your yard, a terminal or the shoulder.
How can we prevent DPF problems in the first place?
Put your trucks on PM-C service, which includes a managed regen and an ECM/TCM sweep. Tier 3 accounts also get live fault-code monitoring through Samsara and Geotab.
Is a forced regen always the fix?
Not always. A clogged filter is often a symptom. Full diagnostics confirm whether the cause is soot load or a failed sensor, a wiring issue or another fault upstream.
How is DPF service priced for fleets?
Pricing for contracted fleets is included in your fleet maintenance proposal, following a complimentary yard audit. For a truck down now, call dispatch.
