Trucx Performs Complete DOC and DPF cleaning in a single Mobile Visit.
Trucx dispatches a fully equipped mobile unit to your fleet yard, truck stop, or job site. Every DOC and DPF cleaning service is completed without one-box disassembly, where all five aftertreatment components are cleaned in place, on the truck, in the correct upstream-to-downstream sequence.
No extraction. No seal replacement risk. No additional downtime from component removal and reinstallation.
What every Trucx service covers:
Every service is verified with a free before-and-after diagnostic measuring DOC conversion efficiency delta, DPF backpressure improvement, and SCR NOx output.
If your diagnostic readings don’t show measurable improvement across all cleaned components, you don’t pay. Service available across Toronto, Brampton, Mississauga, and the rest of Canada.
Many operators mistakenly focus only on the DPF when dealing with recurring fault codes, derates, or excessive backpressure.
However, a clogged or contaminated DOC often remains the underlying cause of repeated DPF failures. Without restoring DOC efficiency, even a freshly cleaned DPF can become restricted again within a short period of time.
Key reasons DOC cleaning is essential include:
For long-term reliability, DOC and DPF cleaning should be performed together as part of a complete aftertreatment maintenance strategy rather than treating each component separately.
A DPF-only service on a truck with a contaminated DOC results in a predictable outcome: the DPF re-clogs within weeks. The regeneration cycle that should clear accumulated soot still fails to complete because the DOC cannot reach the required exhaust temperatures.
This is the structural flaw in how most dealerships and DPF shops approach aftertreatment maintenance, they treat the DPF as the problem, when the DPF is the symptom.
Proper DOC and DPF cleaning addresses the full upstream-to-downstream sequence. A contaminated DOC will re-clog your DPF within weeks. Trucx fixes both in 3 hours.
DOC contamination is not limited to high-mileage trucks. Any diesel with an aftertreatment system operating on short-haul routes, low-load cycles, or poor-quality fuel is at risk. The following operators should prioritize DOC and DPF cleaning as their next service interval:
Don’t service the DPF and leave the contaminated DOC in place. Trucx delivers complete DOC and DPF cleaning on-site, in 3 hours, with a results-based warranty and a free diagnostic included in every booking.
Available 24 hours a day, 7 days a week, coast to coast across Canada.
A DPF-only service leaves the upstream contamination source intact. Here is what distinguishes full DOC and DPF cleaning from a standard DPF-only approach:
The DOC sits upstream of the DPF and generates the exhaust heat required for active DPF regeneration. When it becomes contaminated with SOF deposits, sulfur compounds, or hydrocarbon buildup, regen cycles fail to complete — and the DPF re-clogs rapidly regardless of how recently it was serviced.
DOC and DPF cleaning should always be performed together. Cleaning the DPF in isolation without addressing DOC contamination treats the symptom and leaves the cause untouched.
The most reliable indicators are repeated DPF failures after recent cleaning, active fault codes SPN 3246 or SPN 4094, incomplete regen cycles that abort before completion, and low measured exhaust temperature entering the DPF during a regen event.
Trucx’s free pre-service diagnostic measures DOC conversion efficiency directly, which confirms whether contamination is the root cause before any billable work begins.
Pricing is determined by vehicle platform, engine type, and service scope. Trucx provides a fully transparent upfront quote after the free diagnostic, no towing or transport costs added because the mobile unit comes to your location. Call 365-773-3266 for a same-day quote.
Yes. Trucx’s no-disassembly process cleans the DOC, DPF, SCR, EGR, and Turbo entirely in place — on the truck, on-site. No component extraction, no seal or gasket replacement required, no additional downtime from removal and reinstallation. This is how the full DOC and DPF cleaning service is completed in 3 hours or less.
The complete service from pre-service diagnostic, DOC clean, DPF clean, SCR, EGR, Turbo, to post-service verification with before-and-after readings is finished in 3 hours or less at your location. That compares to 2–3 days at a dealership or off-site shop that, in most cases, won’t address the DOC at all.
