V40 AdBlue Tank Issue

I'm having trouble with my 2015 Volvo V40 diesel. The AdBlue tank seems empty even after refills, triggering an error and storing a fault code. Now the engine won't start. Could a defective AdBlue output from the tank to the dosing unit be the problem?

I've had similar issues with my V40. AdBlue problems can be a real pain. Is your fuel efficiency also suffering? I noticed mine dropped before the service light came on. Did you check the SCR catalyst?

Fuel efficiency hasn't changed, and I haven't checked the SCR catalyst. Besides the output, could a faulty AdBlue pump also cause this?

It's possible, but the tank issue you mentioned sounds more likely based on my experience. With all those symptoms, I'd recommend a workshop visit. Better safe than sorry with emissions control.

Thanks for sharing your experience. A workshop visit was the right call. The AdBlue output was defective. Replacement and labor cost 250€. Now the Volvo runs perfectly again.
