Trucx Performs Complete EGR and DPF cleaning in a single Mobile Visit.
A restricted or seized EGR valve doesn’t just reduce engine efficiency; it directly harms your DPF by increasing the amount of unburned hydrocarbons and carbon particulates entering the aftertreatment system. This forces more frequent and less effective regen cycles, which in turn contaminates the DOC and compounds the problem.
Here’s why DPF cleaning alone is a temporary fix:
Proper EGR and DPF cleaning must follow the correct sequence: clean the EGR system first to eliminate the source of the excess soot, then clean the DPF. This is the only way to restore the system to full health and extend the time between service intervals.
Trucx dispatches a fully equipped mobile unit to your fleet yard, truck stop, or job site. Every EGR and DPF cleaning service is performed without one-box disassembly, where the EGR valve, EGR cooler, DPF, DOC, SCR, and Turbo are all cleaned in place, on the truck, following the upstream-to-downstream sequence.
No component extraction. No coolant system draining. No gasket replacement risk. The entire service is completed in 3 hours or less.
What every Trucx service covers:
Any modern emissions-compliant diesel engine operating on recirculating exhaust accumulates deposits in the EGR system over time. These operators are most at risk and should prioritize EGR and DPF cleaning as their next service interval:
Don’t clean the DPF and leave the EGR system fouled. Trucx delivers complete EGR and DPF cleaning on-site in Toronto, Brampton, Mississauga, and across Canada, in 3 hours, with a free pre-service diagnostic and a results-based warranty on every job.
Available 24 hours a day, 7 days a week, coast to coast across Canada.
A fouled EGR valve recirculates dirty, carbon-laden exhaust into the combustion cycle, producing more soot per combustion event and loading the DPF at an accelerated rate. Clean the DPF without fixing the EGR, and the filter re-clogs in weeks at the same elevated rate.
Trucx performs EGR and DPF cleaning in the correct upstream-to-downstream sequence: EGR valve and cooler first to normalize combustion, DPF second once the soot source has been neutralized. That sequencing is what makes the DPF service interval last.
The EGR valve controls flow rate and is prone to carbon seizure at the valve seat and stem. The EGR cooler is the heat exchanger that reduces recirculated exhaust temperature before it enters the intake — it fails by accumulating soot deposits inside its gas-side passages, restricting flow and degrading thermal efficiency.
Both fail independently, by different mechanisms, and both require cleaning. Most EGR services address only the valve. Trucx cleans both in a single EGR and DPF cleaning visit.
Active fault codes SPN 27 (EGR valve position), SPN 412 (EGR temperature), or SPN 2659 (EGR mass flow) are direct diagnostic indicators.
Operationally: sustained power loss under load that hasn’t resolved after DPF service, visible black smoke at normal operating temperature, and DPF re-clogging faster than expected after a recent clean all point to EGR contamination as the primary root cause.
Trucx’s free pre-service diagnostic confirms EGR flow rate and valve function before any billable work begins.
Yes. Trucx’s no-disassembly process cleans the EGR valve, EGR cooler, DPF, DOC, SCR, and Turbo entirely in place on the truck. This is how complete EGR and DPF cleaning across all six aftertreatment components is finished on-site in 3 hours.
Pricing depends on vehicle platform, engine type, and service scope. Trucx provides a fully transparent upfront quote after the free diagnostic. And since the mobile unit comes to your location, there are no towing or transport costs added to the invoice.
