If the AdBlue warning light on the Nissan Qashqai does not turn off after refuelling, there are several possible causes: a faulty or dirty level sensor in the tank; an error in the software of the control unit managing the AdBlue system; an incorrect refuelling procedure (for example, if done with the engine running); a fault in the pump, injector, or the control unit itself (less common but possible).

You can try leaving it idling for 5 to 10 minutes: sometimes the system takes time to recognise the new level; alternatively, take a 15 to 20-minute drive on an A-road to activate the SCR system and force an update.

If your model has a manual reset option, take advantage of it: turn on the ignition and hold the "ok" button on the steering wheel for 10 to 15 seconds. If nothing works, visit a mechanic with advanced diagnostic tools that can read error codes and attempt to reset the AdBlue control unit or force a regeneration of the level sensor.

Otherwise, you will need to contact a Nissan dealer: if they suggest replacing the control unit (over £3,000), refuse. For a 2019 vehicle, a software update should suffice.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
