Yes, it is possible to clean an EGR (Exhaust Gas Recirculation) valve without removing it from the engine, though the effectiveness might be limited. You can use a specialized EGR cleaning spray or intake cleaner, directing it into the valve while the engine is running to help dissolve carbon buildup. However, this method may not reach all areas of the valve thoroughly, and for a more complete cleaning, removal is often recommended. Always follow the manufacturer's guidelines and safety precautions when attempting this.
