Very good product! I used it on a Peugeot 1.6 blue hdi 2018 because for the second time the ad blue warning light came on with a countdown immobilizing the car after about 6 kilometers. After I added it to the adblue tank, the warning light turned off and only the lambda sensor light remained, which stayed on because a fault was recorded in the ECU, but it can be cleared with a diagnostic tool! The first time, two years ago, I fell for the dealership's story and paid 400 euros because the warranty did not fully cover it! This product saved me from paying 1200 euros this time! Use it with your eyes closed!

On a Peugeot 2008 model from 2017 with 120,000 km, the service light turned on, the AdBlue light was flashing and it was still giving me 1100 km. With a double dose of the product and after about 160 km of steady driving on Attiki Odos, all the lights went off. That's all from me, I hope I helped.

Peugeot 308 1.6 120ps fault in the adblue with a warning for 1100 km before immobilization. I used this specific product and cleared the fault. After 2000 km so far everything is fine.

I also had the engine warning light on in my Peugeot 208 with an AdBlue pump indicator (P20A2). I would reset it at the garage and it would come back on again in 2 days. I filled up with fresh AdBlue from a reputable brand and also added a bottle of this (125ml). After a week and about 100km, the light turned off on its own! It saved me from replacing the pump, which would have cost at least 1000 euros!

low urea pressure in ds 1.6hdi with 155,000km one bottle in the tank and it worked wonders! every time I would clear the fault until at some point after 100km it never came back on again

I have a 2016 C3 and I got the check engine warning along with the UREA indicator flashing. I had another 1,100km before the engine would stop starting. It was the second time I had this problem because the first time I actually went to the workshop and they replaced the injector because it was filled with crystals. I thought I'd try it to maybe save the 280€. After 300km, the message that it would stop in 1,100km disappeared, and after another 100km the UREA indicator turned off, and finally after another 50km the check engine light turned off as well. I hope this helps you too.

Like other people in the reviews, I also had an issue with a 2017 Peugeot 208 that showed a problem with the SCR. I decided to try this before taking the car to the workshop and being charged a fortune. I bought the 500ml package and initially put half (250ml) into an almost full AdBlue tank. I drove 100km like that but saw no improvement. Since I had nothing to lose, I decided to try putting in the rest of the package, so I added the remaining 250ml to the tank and after another 80-100km of driving, all the warning lights turned off. From now on, I will add a small package with every refill I do.

I installed it in an Opel Grandland diesel and it turned off the warning light for the ad blue problem; in fact, I put in two, one with 5 liters and the other with 10 liters of ad blue, and it never lit up again. The best thing ever

Unlike what is mentioned in other reviews, although the product was used preventively, after 500km there was a malfunction of the urea injector (adblue), resulting in its replacement (~250 euros) on a Citroen C4. Obviously, no one knows if someone else was the reason, however, the workshop (authorized) was adamant that such products should not be used and that the A and the Ω are the quality (and the production date) of the adblue... Personally, I will not use it again even if I cannot be sure that it was responsible for the failure.

I used it on a 2018 Peugeot 208 diesel that gave me a notification, and since I put it in, I am carefree! Make sure to use good AdBlue... don't be stingy. The damage that will occur is in the thousand. And with every refill, use this little bottle. Must!

Based on comments I read about the product, I decided to try it myself. Peugeot 2008 2018 bluehdi. Breakdown and technician's fee for 1000 + damage. As soon as I put it in, the fault disappeared after a few kilometers and everything is fine, just as I read in the previous ones. It is essential to top it up after every refueling of adblue to avoid crystallization in the adblue catalyst

Guys, I had an issue with AdBlue showing "weak start at 1100km."

Peugeot 2008 '16 Diesel BlueHdi 120hp

I took it to the dealership, they did a reset to see if anything would change, otherwise they told me 1000 euros for the new system.

I bought the fluid, put it in the tank, and after 20 kilometers, EVERYTHING disappeared.....

I'm waiting to see if it will stay that way, but it seems the issue is resolved.

From now on, it's ESSENTIAL to fill up with AdBlue because it will continuously clean the system from the inside.

I was saved!!!!!!!
It had a catalytic converter issue and with the comments I read from another homeopath friend, I installed it, drove several kilometers for 2 days, and it cleared up! Opel Grandland diesel car

Qashqai j11b 2019 1.5 dci 115ps
It gave me a warning while I was traveling and I got worried that I had a major problem.
Before taking any action, I got this additive, put it in the adblue tank, filled it up to the top and drove for 15 km. The lights went off and everything returned to normal!
I recommend it, it did the job and I will now use it every time I refuel adblue.
A small bottle is enough for one refill.
All this happened because the fuels we use don't have additives to prevent the system from clogging.
So we buy them ourselves and pay attention to have them!
I experienced it and luckily learned it cheaply!
I cleared the remaining check with my mobile through the OBD port.
