Diesel Exhaust & Emissions System Repair
in Clackamas, OR.
Modern diesel engines are powerful and efficient—but they rely on complex exhaust and emissions systems to keep them running clean. When these systems fail, you may see warning lights, limp mode, or excessive smoke. At Rob’s Automotive Repair Center in Clackamas, OR, we provide complete diesel exhaust and emissions repair, including DPF cleaning, EGR service, and DEF system diagnostics. If you’re searching for diesel exhaust repair near me, we’re your trusted local solution.
Why Diesel Emissions Systems Matter
DPF — Diesel Particulate Filter
Traps soot from exhaust gases and requires periodic regeneration. We diagnose plugged filters, failed regens, and replacements.
EGR — Exhaust Gas Recirculation
Lowers combustion temperatures to reduce NOx emissions. Common failure points: stuck valves, clogged coolers, blown gaskets.
SCR & DEF Systems
Inject diesel exhaust fluid to neutralize NOx pollutants. We service DEF tanks, heaters, injectors, and dosing modules.
NOx & Pressure Sensors
Monitor exhaust performance and trigger faults when out of spec. We diagnose and replace failed sensors and wiring.

Diesel Particulate Filter (DPF) Service
A clogged or failing DPF can cause: We offer: Our goal is to restore proper operation and prevent costly damage.
- Reduced power or limp mode
- Frequent regenerations or failed regen cycles
- Check engine lights for emissions codes
EGR System Repairs
The EGR system is prone to carbon buildup. Common issues include: We provide: Restoring your EGR system improves airflow, combustion, and overall performance.
- Rough idle or stalling
- Excessive black smoke
- Poor fuel efficiency
DEF & SCR System Repairs
Newer diesels use DEF (Diesel Exhaust Fluid) to reduce emissions. Problems we fix include: We perform DEF/SCR diagnostics and repairs to keep your diesel compliant and reliable.
- DEF pump or injector failures
- Crystallized DEF clogging lines
- Faulty NOx sensors triggering warning lights
Exhaust System Repairs
Not every issue is emissions-related. We also repair: A solid exhaust system keeps your diesel quiet, safe, and efficient.
- Exhaust leaks at manifolds, flex pipes, or joints
- Turbo downpipes and mufflers
- Upgraded exhaust components (compliant with emissions requirements)
