The AdBlue system is something the Devil created. At least if you ask a Swedish mechanic. The cheating is impossible to detect.
A mechanic, who wishes to remain anonymous, now admits that he intentionally cheats and disconnects the Adblue system on diesel cars.
This is even though it is actually illegal to disconnect the system. In the worst case, cheating, if discovered, can result in a fine.
Carup writes.
The mechanic the media outlet spoke to says the system is terribly poor. But he also acknowledges that disconnecting the system is a last resort.
– It's a bad system that's expensive to repair. You have to replace the entire tank because it's encapsulated there, and the tank costs about 30,000 kroner, says the mechanic.
Ulf Stefansson, an expert at Fordonsjuristen, tells Carup that it is illegal to decrypt the Adblue system. But it is also almost impossible to detect if it were to happen.
Adblue, which was developed as an additive for diesel cars to achieve cleaner combustion, was developed far too quickly, according to Carup.
The additive, which came on the market shortly after Volkswagen's methods were exposed in the dieselgate scandal, has, according to the Swedish mechanic, a tendency to self-destruct.
And once it's gone wrong, it's expensive to fix. According to the mechanic, disconnecting is the last resort. But the repair itself is often something that ordinary drivers simply can't afford.
But changing or disabling the Adblue system means that the diesel car will lose its Euronorm classification. And that violates the type approval regulations.
In Sweden, however, Tord Fornander, chairman of the Swedish Regulatory Industry, believes that the disconnection fraud is more than difficult to detect. It simply cannot be done with the tools that the authorities use today.
Instead, the chairman calls for tools 'like they have in Germany'. According to the Swedes, here the authorities can see whether drivers have switched off the statutory system.
While at least the Swedes admit that AdBlue systems are being disconnected, another mandatory technology in modern cars could very easily become the next 'victim'.
Since July 2024, all new cars sold in Europe have been equipped with a so-called 'intelligent speed system', something that makes it impossible for drivers to drive too fast. Read more about it here .
