Video tutorial

In this video, we will see how to behave if the urea warning light comes on in our Peugeot 308. In addition to this, the system warns us by telling us how many kilometers of autonomy we have left before the engine does not restart due to lack of additive.

Therefore, we need to fill the tank to avoid problems.

Let's get the additive, and let's not skimp on the purchase, because a low-quality product could damage the system. Let's also pay attention to how the product has been stored: if it was exposed to the sun, it will surely not be a good deal.

The tank is located in the rear trunk, under the panel and under the storage compartment, or the spare wheel if present. We find the cap on the right, open it and fill the tank: this will be enough to reset the warning light.
