Thanks for the quick reply! Where exactly are the AdBlue lines located? Is it something I can check myself without special tools? And if it is crystallized, what's the best way to clean them? I don’t want to damage anything further.

Located near the AdBlue tank, running to the injector on the exhaust. Visual inspection only possible without tools. Crystallization confirms output issue. It's best to take to a workshop before further damage, could be expensive.

Okay, that sounds a bit beyond my capabilities. I appreciate your advice! I'll book it in with a workshop. The AdBlue output from the tank to the dosing unit was indeed defective. Cost me 250€ to repair. Thanks again!

Possible AdBlue pump failure or blocked injector. Check AdBlue lines for crystallization. You can try clearing the error codes, but it will likely return if the underlying issue persists.
