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

I used this additive for my Peugeot 3008 Diesel, which is known for having a rather sensitive AdBlue system. Before using Wynn’s Crystal Clean & Protect, I kept getting error messages and warnings related to the emissions system. After adding this product regularly, the issues stopped completely. The system ran smoothly without any faults.This is one of the few additives that actually delivers real results. It helped keep everything clean and running properly - especially on long drives.I’ve since sold the car and won’t be going back to diesel again, but this additive was an absolute lifesaver while I had it. Highly recommended!

Works well. Better to prevent then to fix.

No issues 12 months in using this product.

Kept getting NOX warning and AdBlue faults on Peugeot Partner van, including dreaded 'going to not start in x miles'.Added this to the adblue tank in desparation before heading to a garage. Four days later, the lights started to go out, after a week and all is well again. Recommended

Urea orange ight was coming on. I had plenty of Adblu in my Citroen Berlingo 2017.Had it checked out, diagnostic indicated low pressure, the garage cleared my codes, and the area light came back on. This time the Urea light was flashing, warning to stop starting van starting in 700 miles!Tried this product, poured it in the AdBlu tank, left it over night.Following day, the Urea light went off, but then came back on after 80 miles. Used the van again today, Urea light went off again after about 3 miles, and so far it’s stayed off since.So fingers crossed, this product has sorted it out 🙏

Now I don't have the amber light on my dashboard, so it worked i suppose.
