In this video, the YouTuber shares his experience with a common issue in vehicles equipped with the AdBlue system: at one point, the display showed "engine error: repair immediately". He went to Peugeot, where they diagnosed a broken AdBlue tank. Replacing the tank costs over £1,300, so he wisely said he would think about it for a moment.

Back home, using his OBD11 scanner, he found that the issue was actually a blocked filler pipe: he replaced it, and the error disappeared immediately, at a minimal cost.
