Compatible with all AdBlue and DEF fluids, it ensures precise dosing, reduces costly repairs, and supports fuel efficiency. Easy to use at every refuel, it’s the essential maintenance upgrade for diesel vehicles aiming for reliability and compliance. ## Description A clean and well-functioning SCR system is essential for diesel vehicles with AdBlue© technology. This additive has been specially developed for use in the AdBlue© tank and prevents the formation of harmful crystals that can affect SCR performance. Over time, crystalline deposits can form in the tank, injector or pump that hinder flow, decrease system efficiency and cause expensive repairs. This additive works at the first signs of crystal formation, keeping important SCR components clean and free from blockages. It supports smooth operation, precise dosing and optimal NOx reduction - for compliance with strict emission requirements for diesel engines. Regular use of this AdBlue© additive extends the life of the SCR system, reduces the risk of breakdown and reduces vehicle downtime. It improves energy efficiency, vehicle reliability and ensures continuous compliance with emission standards. Compatible with all standard AdBlue© and DEF formulations, this additive is easy to handle - add directly to the AdBlue© tank when refueling. A 125ml bottle holds up to 15 litres of AdBlue© and provides a practical and economical solution for preventive maintenance. For optimal protection, use is recommended at every refueling. Review: Muy buen producto,65000 km con él y de momento el sistema de adblue no me ha dado fallos. pero tengo una duda, qué diferencia hay entre este y el del bote morado de la misma marca ? Review: Cosa dire … questi prodotti sono difficilmente valutabili in quanto la loro efficacia è spesso la risultante di un continuo utilizzo fino a quando i sistemi scr non vanno in panne ossia dopo i 200.000 km circa . La mia recensione si basa sul fatto che quasi tutti i meccanici che conosco mi hanno consigliato esclusivamente questo prodotto, che sto usando seppur la mia vettura sia piuttosto giovane quindi la vera efficacia non è ancora valutabile ## Features - ✅ PREVENTS THE FORMING OF CRYSTALS IN ADBLUE SYSTEMS: This additive specially developed for AdBlue prevents the formation of harmful crystals in the SCR system (selective catalytic reduction). It cleans key components such as the injector, pump and AdBlue tank, ensuring consistently efficient operation of the exhaust aftertreatment system - reducing the risk of expensive repairs caused by crystalline deposits. - ✅ EXTENDS THE LIFE OF SCR COMPONENTS: Over time, it may occur – especially in vehicles with high mileage or frequent idle – slight crystal formation in the SCR system. The advanced formula of this additive works specifically against these deposits in the AdBlue tank, injector and pump. Regular use ensures precise dosing and permanently reduced emissions - for a more effective exhaust aftertreatment. - ✅ IMPROVES THE PERFORMANCE OF ADBLUE SYSTEMS: With regular use, this product improves SCR performance by keeping all important components clean. Clean injectors and pumps allow for more precise AdBlue dispensing, reducing emissions and supporting better fuel efficiency while maintaining environmental standards. - ✅ HELPS AVOID DISTURBITIES AND SYSTEM FALLS: Crystal formation in the AdBlue system can cause unexpected failures and maintenance problems. This additive helps to avoid such problems, supports smooth engine operation and reduces the risk of sudden SCR failures - especially suitable for light vehicles (passenger cars). - ✅ SAFE FOR ALL ADBLUE VEHICLES - EASY TO USE: Compatible with all diesel exhaust fluids (DEF) and AdBlue systems. Simply place directly into the AdBlue tank without tools. A 125ml bottle treats up to 15 litres of AdBlue - a cost-effective solution for preventative maintenance at every refueling process. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BV7BNHDT | | Best Sellers Rank | #54,542 in Automotive ( See Top 100 in Automotive ) #249 in Oil & Fluid Additives | | Brand | Wynn's | | Customer Reviews | 4.5 4.5 out of 5 stars (2,002) | | Date First Available | 17 May 2024 | | Item model number | 21002 | | Manufacturer | Wynn's | | Manufacturer Part Number | 21002 | | Package Dimensions | 31.8 x 21.3 x 4.4 cm; 0.14 g | ## Images ![stabilizing/protective AdBlue additive, 125 ml - Image 1](https://m.media-amazon.com/images/I/61PjKa6yTGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***N on 24 February 2026* Muy buen producto,65000 km con él y de momento el sistema de adblue no me ha dado fallos. pero tengo una duda, qué diferencia hay entre este y el del bote morado de la misma marca ? ### ⭐⭐⭐⭐⭐ Review *by M***E on 28 December 2025* Cosa dire … questi prodotti sono difficilmente valutabili in quanto la loro efficacia è spesso la risultante di un continuo utilizzo fino a quando i sistemi scr non vanno in panne ossia dopo i 200.000 km circa .

Danach ging allerdings die Adbluelampe nicht aus, es kam die Meldung 'in 1000 km kann der Motor nicht mehr gestartet werden'. Das zählte alle 50 km weiter runter und es kam zusätzlich die Motor-Lampe. Mein freundlicher Werkstattmeister sagte, dass bei diesem Typ sehr oft in diesem Fall der Adbluetank getauscht werden muss, der kostet so etwa 1000 €, weil da die Punpe und die Elektronik mit dem Tank eine Einheit ist, plus seine Arbeitskosten. Er stellte mir die Fehleranzeige wieder zurück, um mir Zeit zum Nachdenken zu geben. Am nächsten Tag ging allerdings der Countdown auf dem Display wieder los. Einem Tip aus einem Forum folgend habe ich mir angeschaut, welche Lösungen es für solche Fälle gibt ... und landete bei Adblue-Zusatzflüssigkeiten, die das Auskristallisieren von Adblue verhindern sollen und sogar die Kristalle wieder lösen sollten. Mir fielen da zwei Mittel auf, deren Hersteller mir seit Jahrzehnten bekannt waren: Wynn's und Liqui Moly. Beide gibt es bei Amazon und ich bestellte beide. Der Unterschied: Wynn's kommt in einer kleinen 125ccm-Flasche mit langem Hals, praktisch fürs Einfüllen, und empfiehlt den ganzen Inhalt auf einmal in den Adblue-Tank zu kippen. Die Anderen empfehlen jeweils bei jedem Tanken nur 25 ccm. Meine Strategie war ganz logisch: ich wollte zunächst Wynn's Tinktur ausprobieren und wenn das nicht hilft, in der praktischen Wynn's-Flasche die andere Tinktur nachkippen. Zu Letzterem kam es dann allerdings nicht mehr: Wynn's Cristal Clean & Protect reingekippt, zur Autobahn gefahren und dann nach etwa 5-7 km ging die Adblue-Lampe aus! Am nächsten Tag bei einer längeren Dienstfahrt ging dann nach 20 km auch die Motor-Lampe aus. Und blieb aus! Die kleine Wynn's-Flasche kostete mich übrigens weniger als ein Fünftel von dem Rechnungsbetrag, den mein Werkstattmeister fürs Zurückstellen der Fehleranzeige verlangt hat... ## Frequently Bought Together - Wynn's stabilizing/protective AdBlue additive, 125 ml, 21002 - 2 bottles DPF Filter Purge: The Most Economical Way to Clean and Protect Your Diesel Particulate Filter, Diesel Additive, High Performance Helps Regeneration No Assembling 500ml 16.9 oz x 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/652839302-stabilizing-protective-adblue-additive-125-ml](https://www.desertcart.fr/products/652839302-stabilizing-protective-adblue-additive-125-ml) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-22*
