Wynn's Anti Cristallisant Adblue Vehicles Commercial, Additive Adblue Anti Crystallization 500ml

AdBlue in diesel cars is a complete pain. It’s temperamental, and I’ve already spent a significant amount on replacing the EGR valve and NOx sensor. I recently had the engine management light come on with a warning to stop after 600 miles, which happened after topping up the AdBlue (third-party).After checking various forums, it seems that AdBlue can crystallise on the NOx sensor, causing the engine management light to come on. If your issue is related to that, as mine was, I bought this product for my car, thinking adding more would resolve the issue. However, my car was already full of AdBlue, so I could only add about half of it into my VW. Remarkably, the AdBlue deficiency warning disappeared immediately.I took the car for a drive and restarted it a few times, but the engine management light didn’t go away right away. However, the next day, like magic, the engine management light vanished, and since then, the car has been running perfectly with no further issues.In future, I’ll be using this product for all my AdBlue top-ups. Strongly recommended before taking your car to a dealership – an absolute 5-star product!

It worked and cleared the adblue system of crystals.

So far has kept the addblue from crystalising.

Always put it in with your adblue , stops you having expensive bills

Tried this product in pure desperation when my Porsche Macan diesel displayed the dreaded '600 mile countdown to engine shut-off' message. I had refilled the Adblue to the brim, but the warning remained on. I then went for a drive hoping for the ecu to reset the warning. Nope, the warning light remained on.Jumped on some Porsche forums and was met with scary tales of massive bills to get this sorted due to Adblue Crystallisation. Forums stated that it could be the Adblue float, pump, injector or all 3!!Finally a forum member recommended this product as worth a try. So I did. I added the correct dosage, went for a 15min drive with plenty of bends to make sure the additive got thoroughly mixed, then Bing!! Light went off and has stayed off. Brilliant stuff.Will be using it religiously on every Adblue top-up from now on.

Bought this after having issues with my nox sensors on my car. After a long run engine light would pop on and cause errors, so after looking online and asking on forums etc, a few people mentioned to give this product a go. Thought for money i would give it a go, considering nox sensors for my vehicle are near off £500 each..... Glad they did as errors haven't come back and no engine light now after a long drive. Brilliant product and really does work.

I buy this product for my bmw g31 because i had the pump from adblue withlow presure i think adblue just cristalise on pipes so i put the hole bottle in the tank after 150 miles the fault gone by him self ! Happy days

I could have bought this cheaper on ebay but Amazon Prime got it to me a lot faster. The 500ml is much better value than the 125ml which is why I bought it. As for results, time will tell.
