Technical inspection: illegal deactivation of AdBlue detected from January 2025 ?

The technical inspection of vehicles (particularly Diesel) in France is set to undergo a major change from January 1, 2025 with a tightening of the rules specifically aimed at combating manipulation of anti-pollution systems. This reform comes at a time when breakdowns linked to the AdBlue system, which is used in diesel vehicles to reduce pollutant emissions, are increasing.

A reprehensible practice

Faced with these significant and recurring expenses, many motorists have opted for an illegal solution: deactivating the AdBlue system. Until now, this practice could be carried out for a few hundred euros at unscrupulous garages that used special software to remove the system without leaving any traces detectable during technical inspections.

Punishable by a fine of up to 7,500 euros, this fraud was considered by some to be financially advantageous compared to the recurring costs of repairs related to l’AdBlue.

However, from 2025, technical inspection centres should be equipped with more sophisticated diagnostic devices that will be able to detect these modifications – even those that previously escaped standard checks, believes Auto Plus. This development would aim to protect the environment and public health by combating excessive greenhouse gas emissions.

This new regulation will probably result in an increase in the cost of technical inspections. More importantly, vehicles identified as emitting too many polluting gases, whether or not they have been modified, risk being taken off the road if they are not quickly brought into compliance with the standards in force.

This reform therefore marks a important turning point in the fight against automobile pollution in France.
