A software error in the engine control unit prevents the malfunction indicator light (MIL) from switching on if the urea injector stops working. This can lead to higher emissions and poses a risk to the environment.
The DS7 Crossback vehicles affected by this recall were manufactured between 15 May 2019 and 13 July 2022.
Update 5. 9. 2025 The malfunction indicator light (MIL) may fail to illuminate if the diagnostic system of the Selective Catalytic Reduction (SCR) and/or the diesel particulate filter (DPF) malfunctions after a fault code has appeared. This could cause the vehicle to operate without the required warning, and resulting in emissions above the regulatory limits.
The DS7 Crossback vehicles affected by this recall were manufactured between 27 March 2017 and 15 November 2022.
