Understanding EGR, DPF, and AdBlue Systems

Modern diesel engines rely on EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filter), and AdBlue systems to reduce emissions. While essential for cleaner operation, these systems can become problematic over time, especially when vehicles are mainly used for short trips or city driving.

EGR systems recirculate exhaust gases to reduce emissions, but they can become clogged with carbon deposits, leading to reduced performance and poor fuel economy.

DPF filters trap soot particles but often block or fail, triggering dashboard warnings and limp mode.

AdBlue systems use a urea-based fluid to reduce nitrogen oxide emissions, but AdBlue faults can prevent the vehicle from starting or continuing to run normally.

At Rev Tech Automotive, we provide proven software-based solutions that resolve these issues safely, restoring drivability and preventing further damage.
