Diesel Emissions System Service
Modern diesel vehicles rely on advanced emissions systems to reduce harmful exhaust emissions and keep your engine running efficiently. Over time, soot, carbon buildup, and contamination can clog these components, leading to performance problems, poor fuel economy, and costly repairs.
What Does the Diesel Emissions System Include?
Diesel emissions systems commonly include:
- Diesel Particulate Filter (DPF)
- Diesel Oxidation Catalyst (DOC)
- Selective Catalytic Reduction (SCR)
- Exhaust Gas Recirculation (EGR) System
- DEF System Sensors and Components
These systems work together to reduce soot and emissions while improving engine efficiency.
Signs Your Diesel Emissions System May Need Service
If your diesel vehicle is experiencing any of the following symptoms, your emissions system may need cleaning or repair:
- Reduced fuel economy
- Loss of power
- Rough idle
- Excessive exhaust smoke
- Frequent DPF regenerations
- Warning lights or emissions system messages
- Poor throttle response
Carbon buildup and restricted components can affect overall engine performance and lead to expensive failures if ignored.
Why Emissions System Maintenance Matters
Routine maintenance helps keep diesel emissions components operating properly and may help:
- Restore fuel efficiency
- Improve engine performance
- Reduce harmful emissions
- Extend the life of DPF, DOC, SCR, and EGR components
- Reduce soot and carbon buildup
- Prevent costly repairs and downtime
How the Service Works
Diesel emissions cleaning services use specialized equipment and cleaning solutions designed to clean the emissions system without major disassembly. High-volume cleaning foam is used to clean buildup inside the emissions system components including the DOC, DPF, and SCR systems.
Recommended Service Intervals
Many diesel preventative maintenance services recommend emissions system servicing approximately every 15,000–30,000 miles depending on driving conditions, vehicle usage, and operating environment. Severe-duty operation, towing, excessive idling, or stop-and-go driving may require more frequent service.
Keep Your Diesel Running Strong
Routine diesel emissions maintenance can help improve reliability, maintain fuel economy, and keep your vehicle operating at peak performance. Addressing buildup early may help avoid major emissions-related repairs down the road.
