DPF Cleaning Cost
DPF cleaning is usually a planning estimate rather than a fixed price because ash load, filter condition, sensor issues, and downtime can change the invoice. Use this page to prepare questions before authorizing cleaning or replacement.
For cash planning, compare this range with the repair reserve calculator, save invoice details in the truck repair log template, and review the cost methodology before treating any number as a quote.
When This Estimate Is Useful
- Use before approving a DPF cleaning after repeated regens or restriction codes.
- Use during used-truck review when DPF cleaning records are missing or very old.
- Use to separate cleaning cost from sensor, turbo, injector, or EGR root-cause repairs.
| Line item | Planning range | Notes |
|---|---|---|
| Total planning estimate | $350 - $950 | Planning range only. A written shop estimate should list parts, labor, diagnostics, supplies, taxes, and core charges. |
| Diagnostics and shop supplies | $80 - $350 | Often billed separately from parts and core labor. |
| Downtime exposure | $0 - $1,200 | Not a shop charge. Use for cash-flow planning if the truck sits. |
Parts vs. Labor Breakdown
| Line item | Planning range | Notes |
|---|---|---|
| Parts and materials | $0 - $250 | Varies by OEM, aftermarket availability, reman options, and core policy. |
| Labor | $250 - $700 | Estimated using common labor-hour assumptions and heavy-duty shop labor-rate ranges. |
What Affects the Cost
- Whether the filter is cleaned on-truck, baked and blown off-truck, or replaced.
- Ash load, face plugging, cracked substrate, failed sensors, and related aftertreatment faults.
- Labor planning is checked against a $110-$185 per hour shop-rate band, but emergency or metro work can move higher.
- Related damage found during teardown, inspection, scan-tool testing, or post-repair road testing.
Symptoms or Warning Signs
- Frequent regens
- DPF restriction codes
- Reduced power
- High exhaust backpressure
- Fuel economy drop
Can You Keep Driving?
If the truck is derating, showing high-temperature warnings, or repeatedly requesting regen, limit operation and get diagnostic guidance. Continued driving may increase aftertreatment damage.
Regional Cost Variation
Use this as a U.S. planning range, not a local quote. Dealer labor, mobile service, high-cost metro markets, corrosion, parts freight, and emergency scheduling can move a repair above the middle of the range, while routine PM work in a lower-cost market may land closer to the lower side.
Questions to Ask the Repair Shop
- Did the restriction test show ash loading, soot loading, face plugging, or a cracked filter substrate?
- Is the quote for on-truck service, off-truck bake and blow cleaning, or replacement?
- Will the shop document before-and-after restriction readings or cleaning results on the invoice?
- What upstream issue was checked, such as boost leaks, injector problems, EGR faults, oil consumption, or coolant contamination?
- Are differential pressure sensors, temp sensors, clamps, gaskets, or DOC/SCR checks included or separate?
- What regen or road-test result should be recorded before putting the truck back into dispatch?
What to Record in Your Maintenance Log
- Date, odometer, engine hours if available, unit number, and driver complaint.
- DPF Cleaning Cost diagnosis, fault codes or inspection findings, and why the shop chose repair, cleaning, rebuild, or replacement.
- Parts installed, part numbers when available, labor hours, invoice total, taxes, core charges, and warranty terms.
- Photos, scan reports, oil or coolant notes, pressure readings, or road-test notes when they explain the repair.
- Next inspection, retorque, PM, cleaning, or service follow-up triggered by the repair.

Sources and Methodology
- Federal Motor Carrier Safety Regulations, Part 393 - Equipment safety rules used as a reference point for inspection-sensitive systems such as brakes, lamps, coupling devices, and tires.
- Federal Motor Carrier Safety Regulations, Part 396 - Maintenance, inspection, repair, and recordkeeping requirements for motor carriers.
- Diesel Service Technicians and Mechanics - Used for labor-market context around diesel service work. It is not treated as a shop labor-rate schedule or repair-price source.
- Parts plus labor planning methodology - Internal method: estimate likely parts range, labor hours, shop rate, fluids, shop supplies, diagnostics, downtime, and regional variation.
- Shop labor-rate planning band - Internal planning band for comparing labor-hour assumptions against a broad U.S. heavy-duty shop-rate range. Users should replace it with their local written shop rate when available.
- Regional variation and quote comparison policy - Cost ranges are kept conservative when dealer labor, mobile service, metro pricing, corrosion, parts freight, diagnostics, or emergency scheduling may change the invoice.
