Wynns Diesel EGR Cleaner is a specialized aerosol product designed to clean and restore proper function to contaminated Exhaust Gas Recirculation (EGR) systems in diesel engines. This professional-grade 200ml formula contains powerful solvents that rapidly dissolve carbon, soot, and oil deposits that accumulate in the EGR valve, intake manifold, and throttle body, causing performance issues and triggering warning lights. The precision spray application allows targeted cleaning without requiring complete disassembly of components.
For best results, ensure the engine is at normal operating temperature then turn it off. Locate the EGR valve and associated components. Where possible, disconnect the EGR valve electrical connector. Spray liberally onto contaminated surfaces, allowing the product to penetrate deposits. For severely contaminated valves, spray in short bursts and allow the product to work for 2-3 minutes between applications. After cleaning, wipe away loosened deposits with a clean cloth where accessible. Reconnect any disconnected components and start the engine, allowing it to idle for 5-10 minutes before normal operation.
Diesel EGR Cleaner is particularly valuable for addressing common diesel EGR problems including rough idle, power loss, excessive smoke, and illuminated check engine lights. This product provides a first-line solution before considering expensive component replacement. For preventative maintenance, use every 10,000-15,000 miles, especially in vehicles used primarily for short trips or city driving. For comprehensive EGR system maintenance, consider combining with Wynns Diesel Particulate Cleaner for complete exhaust system care.
