FAQ for DPF, EGR & Aftertreatment Systems

It involves modifying or reprogramming the ECM (or ECU) software to disable functions that the vehicle owner no longer considers necessary. These functions may include: • Removal of the EGR (Exhaust Gas Recirculation) system • Deactivation of the DPF (Diesel Particulate Filter) • Deactivation of the catalytic converter or emissions sensors • Removal of the speed limiter or other factory-imposed restrictions These modifications are typically applied to enhance performance, power, or fuel efficiency, according to the user's specific needs.

We perform remote ECM deletions and adjustments without interrupting your operations: Connect your vehicle using a compatible diagnostic adapter (Nexiq/USB Link recommended) Grant remote access via TeamViewer (installation assistance included) Our specialized technicians will execute the required procedures

• A laptop in good working condition • A stable internet connection With these two elements, we can establish a remote connection and carry out the reprogramming process safely and efficiently.

We offer: Instant solution or refund if any issues arise with emissions systems (DPF/EGR/DEF/SCR) after using our programs. 1-week warranty: The customer can verify functionality the same day or next day. If the applied delete causes additional faults, we commit to resolving it within this period. Warranty exclusions: ECM (Engine Control Module) failures or replacements. Software updates performed by the dealership. Damages caused by unauthorized read/decryption attempts.

We recommend the Nexiq USB Link as the best option for ECM diagnostics and reprogramming in heavy-duty vehicles. This adapter is reliable, widely compatible, and works seamlessly with USB Link 1, 2, and 3 versions. In most cases, it connects via the truck's diagnostic port, either through the 6 or 9-pin German round connector or the square OBD2 port. For more product details, visit: www.nexiq.com

• DEF (Diesel Exhaust Fluid): Diesel exhaust fluid, also known as UREA or AdBlue in Europe. It is used to reduce nitrogen oxide (NOx) emissions. • DPF (Diesel Particulate Filter): Diesel particulate filter. Its function is to trap and remove solid particles present in exhaust gases. • DOC (Diesel Oxidation Catalyst): Diesel oxidation catalyst. It helps convert pollutants such as carbon monoxide (CO) and hydrocarbons (HC) into less harmful gases. • SCR (Selective Catalytic Reduction): Selective catalytic reduction system. It is a catalyst located after the DPF, primarily used in EPA10 and newer engines to reduce NOx. • EGR (Exhaust Gas Recirculation): Exhaust gas recirculation system. It reintroduces a portion of burned gases into the intake to lower combustion temperature and reduce NOx emissions. • VGT (Variable Geometry Turbocharger): Turbocharger system with movable vanes that dynamically adjust their angle and gas flow. It optimizes boost pressure across the entire RPM range, improving low-speed response and high-load efficiency.

• Years and EPA Standards Covered: From 2004 to 2024, including all emissions versions and updates (EPA 04, 07, 10, 13, 17, 21, and beyond). • Compatible Brands: We work with all major market brands, including: Kenworth – Peterbilt – Western Star – International – Freightliner – Volvo – Mack • We offer the most comprehensive and reliable ECM reprogramming software, compatible with any engine brand.
