How to Fix Error P15B3 (AdBlue Level Below Minimum) on Peugeot 3008

Model: Peugeot 3008 MK 2, P84 - Years 2016-2023
Part: AdBlue warning light

The video shows how to resolve error P15B3 on a Peugeot 3008: the calculated level of the additive (Eolys) in the tank is below the minimum threshold. The dashboard displays the service light and a warning triangle, with messages such as "engine repair needed" and "low additive level for particulate filter". Using a diagnostic tool, read the code P15B3 and, in the data stream, see that the level is at 150 ml (calculated value, not real) and the particulate filter is at 99% of its life. The solution: top up the additive tank (Eolys). The tank is located under the passenger side, at the rear, covered by a plastic shield: remove a few 10 mm screws and the mounting bracket. You can top up directly on the vehicle using the appropriate adapter kit and about 2 litres of additive, by gravity. Reconnect everything and screw back in. Using the diagnostic tool, access the special functions, then to the programming of the injected additive: you can perform automatic or manual programming. After programming, the level changes to 1,000 ml and the minimum threshold is no longer reached. Clear the code P15B3 and restart the car: the warning lights turn off. Only the service light remains for the overdue service (2,500 km overdue).
