Insignia AdBlue Issue

I'm pulling my hair out! I've got a 2015 Vauxhall Insignia, diesel engine, and it's throwing a fit. The dashboard keeps yelling at me with an error message, and when I hooked it up to a reader, it's showing an AdBlue error. Now, the REALLY fun part? It won't even start now! Checked the AdBlue tank and it seems bone dry despite filling it last month. Could this be the issue? Is my car just super thirsty, or is something else going on?

Sounds familiar. I had something similar happen with my Insignia. Check the AdBlue output from the tank to the dosing unit. Mine was defective. Felt like I was trying to water a plant with a hose that had a massive kink in it – nothing getting through!

Whoa, really? Defective how? Like, completely blocked, or just...leaky? And how did you even figure that out? I'm not exactly a mechanic, more of a 'point and pray' kind of guy when it comes to engines!

Yeah, pretty much blocked. Workshop confirmed it. If your symptoms are identical and the tank's actually full, it's almost certainly the culprit. Save yourself the headache and get it checked. Cost me around 250€ to sort.

Right, gotcha. Thanks a bunch! Looks like a trip to the shop is in order. At least now I have some idea of what to tell them, instead of just standing there like a dummy. Turns out you were spot on! It was indeed the AdBlue output. 250€ later and she's purring like a kitten again!
