Wynn's Crystal Clean & Protect - Additive for Use with AdBlue® - Prevents Crystallisation in SCR Systems - Enhances Diesel Emission Control Performance - 125ml

Good stuff, second time buying and worked perfect in my Diesel car.

Problem had an easy fix after half a day from putting the liquid in and has very good value for money. Would highly recommend.

Very good, reduced crystalisation on my ad blue engine.

Problem with your adblue? should've used this

My 2016 Peugeot 3008. 1.5HDi blue had engine fault repair needed and emissions control fault : starting prevented in 700miles. The UREA dash light came on as well. I topped up the ad blue but the errors didn’t go away. I then put this in the ad blue tank and drove it about 100miles over 3 days. In the 3rd day the emissions warning went. The next day the engine fault error had gone as well. Can’t recommend this enough. I thought my car needed a new ad blue tank which is very costly.

This stuff is amazing. Had the dreaded Adblue system failure message on my BMW 520d. Read other reviews saying it cleared up error messages. Didn’t hold much hope but thought I’d give it a whirl. Added 2 bottles to a full tank of Adblue. It took some time (about 3 months) but one day I switched the car on and the persistent error had gone and no longer any engine light! Will use this now every time I top up the Adblue to keep the crystallisation at bay. Worth its weight in gold!

Recently been getting come adblue faults in my 1.5 bluehdi, had a few codes that came up with urea pressure and for the adblue Injector. I first cleaned the injector upon inspection it looked like nothing had been coming out. So it was either the pump in the tank as live data showed low pressure or the adblue could have crystallised. So rather than spending thousands on the adblue tank as it has everything inside it I thought I’ll give this wynns treated ago! Within 5 minutes of this added to my adblue tank my live data showed it had pressure and urea injection was being injected. Removed fault codes and it’s all fixed! My first bottle I got from a local store but after I realised it had fixed the problem I then wanted to buy another but all shops had sold out and Amazon had availability for Sunday delivery (was Friday when looking) so purchased another bottle but from Amazon as I want to make sure it’s got another treatment in the tank and low and behold Amazon delivery it next day on Saturday which I was hoping for so grats to Amazon for fulfilling this order and getting my my order earlier than expected. If you have similar faults it’s definitely worth buying this just in case you have the same problem and put it in your adblue tank and test before you even go to a garage! It will safe you big money if this is your problem. They say to add 1 of these when you fill your adblue up to prevent these faults and it also cleans so multiple functionally.

Seems to work time will tell

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

Mein Citroen Berlingo zeigte mal wieder die Adblue-Lampe und ich habe beim nächsten Tanken auch Adblue-Flüssigkeit vollgetankt. 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...

Tout s'est bien passé Merci

waste of time

Efficace
