Corsa AdBlue Error No Start

Sounds familiar. I had a similar issue with my Peugeot. Kept getting AdBlue warnings, and eventually, it refused to start. Did you notice any leaks or weird smells around the AdBlue tank?

No leaks that I can see, and no weird smells either. Just the error message and the refusal to start. What was the problem with your Peugeot in the end?

Turned out the AdBlue injector was clogged solid. Probably not the same issue, but the symptoms were almost identical. Best bet is to get it hooked up to a proper diagnostic tool to read the error codes and see what's really going on. Might be a faulty sensor, a bad pump, or something entirely different. Based on my experience if you cannot fix it yourself, its best to go to a workshop.

I think I'll take your advice and book it in. Hopefully, it's something simple. Just got a quote of around 250€ for the whole thing so I am not thrilled, but at least that will fix the SCR catalyst and get me through emissions!
