PSeveral motorists have reported having had a breakdown in their AdBlue tank, driving with a Diesel car, reports La Voix du Nord.
“A few days ago, when starting my diesel car, a worrying message appeared: “engine failure, need repair. Your car will no longer start in 1,100 km.” At the end of the check, I am told that the AdBlue tank needs to be changed and that it will cost me around 1,200 euros: the pump which injects the product into the catalytic converter is an integral part of this tank and it no longer works. It is therefore necessary to replace the tank-pump assembly. And pay. Please note, my car has less than 80,000 km on the odometer,” a reader wrote to The Voice of the North.
The UFC-Que Choisir indicated that it had received 1,700 complaints regarding AdBlue according to information from The Voice of the North. In this same context, a Belgian consumer association announced that it wanted to launch collective action against Stellantis. The company, for its part, claims that “all customers potentially affected by AdBlue problems are fully compensated for parts and labor costs during the conventional warranty period. To address various concerns raised by customers we have voluntarily decided on several occasions to provide special coverages beyond this conventional warranty period. »

AdBlue to blame?
This liquid additive, which reduces emissions of polluting particles from diesel engines and thus makes them less harmful, would be the cause of these automobile breakdowns. Recent vehicles dating from after 2010 are required to have one.
By chemical reaction, the particles making up the additive transform the polluting particles into nitrogen or water, thus making their environmental impact harmless.
AdBlue can crystallize and block the injector. In this case, it is necessary to replace the injector (around 200 euros) but also the AdBlue tank (1,350 euros) and a probe which allows the level of nitrogen oxide to be measured (600 euros). The whole thing ultimately costs the motorist around 2,150 euros, including labor and VAT.
