# A Fresno DPF service scope checklist

A filter-cleaning price may exclude removal, fault diagnosis and reinstallation. Compare filter acceptance, inspection, reporting and logistics before committing vehicle downtime.

## Gather these five details

- Fresno-area location and where the vehicle or removed filter is held
- Vehicle year, engine model and DPF part number if available
- Warning messages, recent service and prior cleaning records
- Whether removal, transport and reinstall are needed
- Number of filters and the required return-to-service window

## Public resources for your property

For a Fresno vehicle or fleet, keep equipment service and CARB compliance records separate. Give the provider the actual engine and filter information; this website does not determine vehicle compliance.

- [CARB DPF problem-resolution guidance](https://ww2.arb.ca.gov/resolving-diesel-particulate-filter-or-dpf-related-problems) 

Use CARB’s installer and manufacturer contact routes for persistent DPF problems; cleaning does not settle an underlying fault.

- [CARB Clean Truck Check overview](https://ww2.arb.ca.gov/clean-truck-check-overview-fact-sheet) 

Check the separate emissions-compliance program for the actual vehicle. A cleaning receipt is not a passing compliance test.

## Five questions for the written proposal

Open a topic for the question to ask and what to compare.

### Accepted filter

**Ask:** Is this exact filter accepted for the process?

Send the part details and ask what condition checks determine acceptance.

### Work boundary

**Ask:** Are removal, diagnostics and reinstall included?

Separate bench service from vehicle labor and underlying fault work.

### Inspection

**Ask:** What checks and before/after records are provided?

A cleaning invoice alone does not describe the filter’s condition.

### Exceptions

**Ask:** How are damaged or unserviceable filters handled?

Agree charges, rejection terms and authorization before replacement is added.

### Logistics

**Ask:** What transport and turnaround terms are confirmed?

Record collection, shipping or drop-off responsibilities and the actual promised window.

Scope planning only. Follow the vehicle and filter manufacturer’s instructions; this is not a cleaning or repair procedure. Local sources are independent of this website.

## Describe your project

Compare off-vehicle filter cleaning with removal, diagnostics and return-to-service work.
