“Protect Your Diesel Engine: Avoid Costly AdBlue Damage!”

Adblue

Mail of engines – This week, Alexis, the owner of the Peugeot 308 in Tarn, wonders how to fill in Adblue, without risking unpleasant surprises.

Question Alexis, Alby (Tarn), owner of the 2018 Peugeot 308 car

“Good morning. I had no problems with Adblue For my car, but I heard a lot of negative things about it. They say that if this is poorly expressed, he crystallizes and trains breakageThe field is so that some deactivate it (even if it is forbidden) … I would like to know if these fears are justified and how not to risk expensive repairs. THANK YOU.”

Indeed, blue crystallization can lead to serious motor problems. The most frequent rupture occurs when the small crystals of Adblue, the injector that sprays the Adblue in the exhaust channel. The filtering system of small particles (SCR system) can also be damaged. You will tell me: “Anything that I am radiating more particles while my car is working.”

Except that the SCR sensor after damage causes engine performance losses. Specifically, the sensor makes errors and gives erroneous information to the system of the central transport system, failures that are sometimes asked to immobilize the vehicle.

But do not worry, four elements that crystallize the liquid are well identified and therefore can be warned. Logically, Adblue crystallizes when it is too cold, but there is a margin, the crystallization point of this fluid is about -11 ° °. In this case, the best solutions are to protect your car from Frost. Parrow your car in the shelter and regularly use it, the liquid will be in motion and will not freeze. Do not forget to close the adblue tank cover well.

This is far from more, crystallization can also arise from a too high temperature. Above 30 C °, the present in the liquid evaporates, and this generates the formation of crystals. Two decisions here seem suitable. The advantage is that they avoid crystallization in all cases mentioned in our answer. Buy an anti -kristalization supplement or, of course, use good quality Adblue, you will find it in a commercial one.

The third point, which pay attention to when you have a car with the SCR system: the effect of air (at all temperatures) Adblue also leads to crystallization! Therefore, you must take care of maintaining an adblue closed tank, storing the liquid correctly if you store it (a well -closed cover, in a relatively fresh one (but for this the car will warn you).

Then be careful, it becomes a little technical. When the engine burning is at a too low temperature (below 260 C °), this also leads to adblue crystallization. This low combustion is explained by other dysfunctions, so you should regularly support your car. Since the breakdown that affects the burning of the engine (for example, the dysfunction of the preliminary heating of the candles) can really lead to complications.

If we hope to answer you, Alexis. We can only give you the last advice. First of all, do not try to remove the Adblue system from your car, you risk a fine of 7,500 euros, to which you will have to add the cost of compliance with the vehicle …
