We specialize in medium-duty trucks, commercial fleets, and diesel-powered vehicles used in on-road, off-road, and industrial applications.

Common signs include: DPF warning light Poor fuel economy Excessive regens Reduced engine power High backpressure readings

Yes, we offer bung repairfor stripped or damaged sensor ports and recore services for filters beyond cleaning.

For on-vehicle ReGenX cleanings, turnaround is 2–3 hours. For off-vehicle services, it’s typically 24–48 hoursdepending on filter condition.

We offer: ReGenX on-vehicle DPF cleaning DPF off-vehicle restoration Bung repair and thread recovery DPF recore services Emissions diagnostics and troubleshooting

Cleaning helps restore filter performance, but if issues persist, we offer diagnostic services to identify problems with sensors, EGR systems, or DEF components.

Yes, we work with fleet managers to provide regular service schedules, priority appointments, and volume pricing.

A DPF is an emissions control device that traps soot and particulate matter from diesel exhaust. It must be cleaned periodically to function properly and meet EPA regulations.

DPF Resolutions is a San Antonio-based service provider specializing in Diesel Particulate Filter (DPF) cleaning, diagnostics, bung repair, recore services, and emissions system solutions for medium-duty diesel vehicles.

Look for reduced fuel efficiency, frequent regens, loss of power, DPF warning lights, or increased exhaust backpressure.

In most cases, no. Our on-location service is designed to clean your DPF without removal. Once onsite, our technicians will assess your vehicle and determine if removal is necessary—but for most vehicles, the filter stays installed, making the process faster and safer for your engine and components.

If the filter is fully plugged or damaged, additional services like a recore or replacementmay be necessary. Our team will assess and recommend the best option.

ReGenX is a proprietary on-vehicle DPF (Diesel Particulate Filter) cleaning process developed by DPF Resolutions. It restores filter performance without removing the DPF, saving time and labor costs.

Yes! ReGenX helps reduce emissions by restoring proper filter function, ensuring your vehicle meets environmental compliance standards.

Unlike traditional methods that require filter removal and shipping, ReGenX cleans the filter while it remains on the vehicle. This reduces downtime and eliminates the risk of damage during disassembly.

Most cleanings are completed within 2–3 hours, meaning you can get back on the road the same day.

ReGenX is ideal for medium-duty diesel trucksand commercial vehicles with accessible DPF systems.

It depends on your engine hours, driving habits, and load conditions, but a DPF should typically be cleaned every 100,000 to 150,000 miles or as needed based on sensor readings and performance.

ReGenX is a non-invasive cleaning method that follows OEM emission standards. It does not void warranties, but we always recommend checking your specific coverage.

Cost Savings: Significantly less expensive than purchasing a new DPF. Performance: Restores filter efficiency and engine performance. Environmental Compliance: Ensures your vehicle meets emission standards. Warranty: Many Recore services come with warranties comparable to new filters.

The process involves: Inspection: Assessing the DPF for damage. Core Removal: Extracting the old, clogged or damaged ceramic core. Core Replacement: Installing a new OEM-equivalent ceramic substrate. Welding & Sealing: TIG welding the housing and ensuring airtight seals. Testing: Conducting flow and pressure tests to confirm performance.

The turnaround time can vary based on the specific filter and workload, but most Recore services are completed within 24 to 48 hours.

Yes, a Recored DPF can be cleaned just like a new filter, following the manufacturer's recommended maintenance schedule.

DPF Recore is a process where the internal ceramic filter (core) of a Diesel Particulate Filter (DPF) is replaced with a new one, while retaining the original housing. This restores the filter's functionality without the need to replace the entire unit.

Absolutely. By reusing the existing filter housing and only replacing the internal core, Recore reduces waste and the environmental impact associated with manufacturing new filters.

Recore offers a cost-effective alternative to purchasing a new DPF. It provides like-new performance at a fraction of the cost, reduces downtime, and ensures compatibility by using your existing filter housing.

Over time, soot and ash accumulate in the DPF, leading to blockages that can cause: Reduced engine performance Increased fuel consumption Potential engine damage Failed emissions tests Regular cleaning removes these deposits, restoring optimal function and preventing costly repairs.

Improved Fuel Efficiency: A clean DPF reduces backpressure, enhancing fuel economy. Extended Engine Life: Prevents engine strain and potential damage from clogged filters. Cost Savings: Avoids expensive DPF replacements and reduces maintenance costs. Environmental Compliance: Ensures your vehicle meets emission standards.

Common indicators include: Illuminated DPF warning light Frequent regeneration cycles Reduced engine power Increased fuel consumption Unusual exhaust smoke If you notice any of these signs, it's advisable to have your DPF inspected and cleaned promptly.

Cleaning intervals depend on vehicle usage: City Driving / Frequent Idling: Every 30,000 to 100,000 miles Highway Driving: Every 150,000 to 175,000 miles

While some DIY methods exist, professional cleaning is recommended to ensure thorough removal of soot and ash without damaging the filter.Professional services also include inspections and testing to verify the DPF's integrity post-cleaning.

The cleaning process typically takes between 24 to 48 hours, depending on the extent of buildup and the specific cleaning methods used.

Our comprehensive cleaning process includes: Inspection: Assessing the DPF for damage or excessive buildup. Thermal Cleaning: Using high-temperature ovens to burn off soot and ash. Pneumatic Cleaning: Employing compressed air to remove remaining particles. Final Inspection: Ensuring the DPF meets performance standards before reinstallation. This process restores the DPF to optimal condition, ensuring efficient engine performance.

A Diesel Particulate Filter (DPF) is an emissions control device designed to capture and store soot (particulate matter) from diesel engine exhaust. This helps reduce harmful emissions and ensures compliance with environmental regulations.

Yes. We use high-quality stainless-steel bungs and professional TIG welding techniques to ensure the repaired bung meets or exceeds the durability of the original fitting.

Bungs can become damaged due to: Corrosion from exposure to exhaust gases and environmental factors Cross-threading or over-tightening during sensor installation or removal Galling, where metal surfaces seize together, often due to lack of anti-seize compound Physical impact or stress from road debris or improper handling

In most cases, a damaged bung can be repaired without replacing the entire DPF. The repair involves removing the damaged bung and welding a new one in place, restoring the integrity of the sensor mounting point.

We provide bung repair services for a wide range of vehicles, including: Light-duty trucks Medium and heavy-duty commercial vehicles Off-road and construction equipment Agricultural machinery

The cost of bung repair can vary based on the specific vehicle and extent of the damage. For an accurate estimate, please contact us with your vehicle details, and we'll provide a detailed quote.

A bung is a threaded fitting welded onto the diesel particulate filter (DPF) or exhaust system. It serves as a mounting point for sensors like EGT (Exhaust Gas Temperature), NOx, or pressure sensors. A damaged bung can lead to sensor malfunctions, exhaust leaks, and potential engine performance issues.

To minimize the risk of bung damage: Always apply anti-seize compound to sensor threads during installation. Use proper tools and techniques when installing or removing sensors. Avoid over-tightening sensors to prevent thread damage.

The repair time can vary depending on the extent of the damage but typically ranges from 1 to 2 hours. We strive to complete repairs promptly to minimize your vehicle's downtime.

Our bung repair process includes: Assessment: Inspecting the damaged bung to determine the extent of the damage. Removal: Carefully removing the damaged bung, which may involve drilling or cutting. Preparation: Cleaning and preparing the area for welding. Installation: TIG-welding a new stainless-steel bung onto the DPF. Testing: Performing pressure tests to ensure a leak-free and secure installation.
