By dissolving deposits and maintaining fluid flow, it protects critical components like the AdBlue tank, pump, and injectors from costly damage. Compatible with all Diesel Exhaust Fluids, one bottle treats up to 15 litres, ensuring cleaner operation, improved NOx emission control, and extended system lifespan—making it an essential maintenance upgrade for modern diesel vehicles. ## Description This AdBlue treatment is specifically designed to prevent costly repairs and breakdowns by eliminating crystallisation in the Selective Catalytic Reduction (SCR) system. Crystallisation can obstruct AdBlue flow and cause significant damage to critical components, leading to expensive maintenance, repairs and system failures. By using this advanced formula, crystallisation is effectively prevented, ensuring that the SCR system remains clean and fully operational. Keeping the system free from crystalline deposits enhances the efficiency of the AdBlue injection process, supporting optimal NOx reduction and maintaining compliance with environmental standards. This powerful treatment provides a comprehensive cleaning effect on all essential components of the AdBlue system. By dissolving light crystallisation in the AdBlue tank, pump unit, and injector, the solution prevents build-ups that could lead to blockages and inefficient performance. A clean system promotes better AdBlue dispersion, improving the overall operation of diesel vehicles equipped with SCR technology. Regular use of this treatment extends the life of AdBlue components, reducing the risk of unexpected failures and costly downtime. Formulated for broad compatibility, this treatment works effectively with all recognised Diesel Exhaust Fluids (DEF) and AdBlue solutions. Its highly concentrated formula ensures optimal performance with small doses, making it an economical solution for maintaining the SCR system. With just one 125ml bottle, up to 15 litres of AdBlue can be treated, providing long-lasting protection against crystallisation and contamination. Designed to support seamless integration into existing AdBlue systems, this treatment delivers reliable and consistent performance across a wide range of diesel vehicles. By preventing deposits, enhancing SCR operation, and prolonging component life, this treatment ensures that diesel vehicles maintain their efficiency and emission control capabilities. Regular use helps prevent breakdowns, optimises AdBlue consumption, and sustains the durability of the entire system. With its advanced cleaning action and protective properties, this solution is an essential addition to any diesel vehicle maintenance routine. Review: Good product - Easy to use , good product Review: Engine Never Worked Better - My car has never run better. It’s like it has a band new engine. It’s quieter, smoother and just working brilliant. I can’t believe the difference ## Features - Causes serious eye damage. - Contains 1,2-benzisothiazol-3(2H)-one. May produce an allergic reaction. - ✅ PREVENTS COSTLY REPAIRS BY AVOIDING CRYSTALLISATION IN THE ADBLUE SYSTEM: Formulated to prevent the formation of harmful crystalline deposits within the AdBlue system, ensuring the proper operation of the Selective Catalytic Reduction (SCR) system. By maintaining optimal fluidity and preventing obstructions, this treatment helps to avoid expensive repairs caused by crystallisation in key components such as the AdBlue tank, pump unit, and injector. Keeping the system clean ensures that costly breakdowns and disruptions are avoided, ultimately reducing downtime and unexpected maintenance expenses. - ✅ KEEPS THE SCR SYSTEM CLEAN AND IMPROVES ITS OVERALL OPERATION: Designed to maintain the cleanliness of the Selective Catalytic Reduction (SCR) system, this treatment ensures that AdBlue flows smoothly through all critical components. By preventing the build-up of harmful residues, the solution enhances the efficiency of the SCR process, enabling optimal reduction of nitrogen oxide (NOx) emissions. A clean system supports a consistent injection process, leading to better fuel economy and lower exhaust emissions. - ✅ ELIMINATES BREAKDOWNS CAUSED BY ADBLUE CRYSTALLISATION AND PROLONGS COMPONENT LIFE: Engineered to dissolve light crystallisation and protect against the formation of new deposits, this AdBlue treatment prevents system failures and extends the life of essential components. Crystallisation can cause blockages and damage to injectors, pumps, and sensors, leading to costly repairs and operational downtime. By incorporating this solution into routine vehicle maintenance, the risk of performance degradation and system malfunctions is minimised. - ✅ CLEANS ALL CRITICAL COMPONENTS WITH A POWERFUL DISSOLVING EFFECT: This formula delivers a targeted cleaning effect on key elements of the SCR system, including the AdBlue tank, pump unit, and injector. By dissolving light crystallisation and preventing residue accumulation, this treatment ensures uninterrupted AdBlue flow and optimal system function. The powerful cleaning action supports precise dosing and efficient NOx reduction, which is essential for meeting emission standards. By actively keeping the system clean, the product enhances the durability of AdBlue components and safeguards the performance of diesel engines fitted with SCR technology. - ✅ COMPATIBLE WITH ALL DIESEL EXHAUST FLUIDS AND HIGHLY EFFECTIVE IN SMALL DOSES: Designed to work seamlessly with all recognised Diesel Exhaust Fluids (DEF) and AdBlue solutions, this treatment provides broad compatibility across different vehicle models and SCR systems. A single 125ml bottle effectively treats up to 15 litres of AdBlue, making it a cost-effective and efficient solution for maintaining system performance. The carefully calibrated formula ensures that the treatment integrates perfectly with existing fluids, delivering optimal protection without affecting the integrity of the AdBlue solution. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Wynn's | | Brand | Wynn's | | Model | Ad-Protect 125ml | | Product Dimensions | 4.15 x 5.8 x 19 cm; 130 g | | Item model number | 21003 | | Manufacturer part number | 21003 | | Item Weight | 130 g | ## Images ![WYNNS Ad-Protect For Adblue®- Prevents Costly System Repairs - 125ml - Image 1](https://m.media-amazon.com/images/I/61tPAi3OBxL.jpg) ![WYNNS Ad-Protect For Adblue®- Prevents Costly System Repairs - 125ml - Image 2](https://m.media-amazon.com/images/I/617svQttAFL.jpg) ![WYNNS Ad-Protect For Adblue®- Prevents Costly System Repairs - 125ml - Image 3](https://m.media-amazon.com/images/I/81P-WRjRoUL.jpg) ![WYNNS Ad-Protect For Adblue®- Prevents Costly System Repairs - 125ml - Image 4](https://m.media-amazon.com/images/I/71nBlN56zsL.jpg) ![WYNNS Ad-Protect For Adblue®- Prevents Costly System Repairs - 125ml - Image 5](https://m.media-amazon.com/images/I/81Zmd9Srh2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by J***S on 18 July 2026* Easy to use , good product ### ⭐⭐⭐⭐⭐ Engine Never Worked Better *by S***N on 1 April 2026* My car has never run better.
