It really works! A must-have for AdBlue diesel engines!
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!

Does the job but don’t ignore a warning light
Does dissolve the crystals , my only warning is if your engine light comes on and off still take your car to a garage and ask them to investigate my pump had ceased and was squirting ad blue everywhere but in to the exhaust system!I now add this each time I add Ad-blue

Essential purchase for diesels
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
