Part: AdBlue warning light

Video tutorial
Detailed instructions - On this model from the German manufacturer, when the AdBlue warning light comes on, it means you need to refill the additive, or you will be unable to start the engine after a certain number of miles indicated on the instrument panel. Therefore, open the fuel door, and next to the diesel fuel cap, you will find the blue cap for the additive tank. At this point, take the additive container and use the appropriate hose to refill it. After that, turn on the ignition and check that the warning light has turned off.

Where to Find the Fuses in the Nissan Qashqai

The fuse box in the Nissan Qashqai's cabin is located to the left of the steering wheel, where there is a small cover. Pull it off to access the fuse and relay box. To replace a fuse, if that is the cause of the issue, take a small pair of pliers and remove the fuse of the non-functioning component. Check that the bridge inside the fuse is not broken; if it is broken, replace the fuse with a new one of the same amperage as the old one. If the bridge is intact, the fuse is functioning correctly.
