How to Reset the AdBlue Warning Light on a Peugeot Expert

Model: Peugeot Expert Mark2, MK 2 - Years 2008-2016
Part: AdBlue warning light

If the AdBlue warning light comes on during normal driving, along with the engine malfunction light, there is likely an issue with the exhaust gas management system. This could involve a lambda sensor that has become blocked due to excessive unburned fuel, the ECU managing the sensor not functioning correctly, or the exhaust gas recirculation valve. It is essential to take the vehicle to a service centre for diagnosis and, if necessary, reset the warning using the OBDII port.
