Peugeot 3008 AdBlue System Error

I've got a 2022 Peugeot 3008 diesel with 212158 km on it. I'm getting an AdBlue error message on the speedometer. There's also an error stored, and the engine won't start. Could this be a defective AdBlue output from the tank to the dosing unit? Anyone else had this?

AdBlue problems, huh? Sounds like a pain. Is your fuel efficiency still decent? Tank capacity should be normal, right? Have you tried just topping off the DEF fluid to see if that clears the error? Could be a simple fix before you go digging deeper.

Thanks for the input. I already tried topping off the DEF fluid, but the error's still there. Could the injection system be at fault, even if the tank is supposedly full?

Well, if topping it off didn't work and you're still getting the error, yeah, the injection system could be acting up even if the tank seems full. It might be worth getting it checked out by a professional to avoid causing any further damage. I mean, what else can you really do?

Thanks for the advice. The workshop confirmed the AdBlue output from the tank to the dosing unit was defective. The repair cost came to about 250€.
