Mini Roadster AdBlue Issue

Okay, so I'm officially stressing out. My 2015 Mini Roadster diesel is throwing a hissy fit. The speedometer is screaming about something, and the error memory says the AdBlue tank is empty. Now, the big problem: it won't start! Could this be related to the diesel exhaust fluid? Is it something with the tank capacity? I've read something about SCR catalyst and the service light is on now. Ugh!

Sounds like an AdBlue issue alright. I had a similar problem with my Mini Roadster a while back. Same symptoms: error message, engine refusing to start. Have you checked the AdBlue injection system? Maybe something is clogged or the pump is failing.

Injection system, huh? Where exactly would I find that on the Mini, and is it something I could potentially check myself, or am I better off just taking it to a mechanic?

Yeah, probably best to get it checked by someone who knows their stuff. On my Roadster, the issue was indeed the AdBlue system – the output from the tank was faulty. If the error memory mentions AdBlue and the car won't start, it's highly likely that's the culprit. Could be a faulty sensor as well, but a proper diagnostic will pinpoint it. No matter what, get the car going again!

Just wanted to let you know, I took the Mini to a workshop, and you were spot on. Seems the AdBlue output from the tank to the dosing unit was indeed defective. Cost me around 250€ to fix, which I guess isn't too bad. Thanks for the help!
