AdBlue issue on Seat Tarraco
Summary of the thread
A 2018 Seat Tarraco owner experienced an issue where the dashboard indicated the AdBlue tank was empty despite being full, leading to a non-starting engine. The suspected cause was a defective AdBlue output from the tank to the dosing unit. Another individual with a similar problem suggested that a faulty AdBlue pump might be the issue. The problem was resolved by replacing the faulty pump, which was confirmed by a local garage.

Fuel efficiency hasn't changed. How did you fix it? Did you have to replace the whole tank or just some components? What about the emissions control, did you notice an increase?

Sounds like the pump. In my case, the dealership confirmed the pump was faulty. Replacing it fixed everything. I recommend getting it checked professionally; otherwise you might end up chasing ghosts.

The local garage confirmed the AdBlue pump was faulty. Replacement and coding cost 250€. Annoying but at least it's sorted. Thanks for the insight!

I had a similar problem with my Seat Ateca. The dashboard alert was driving me nuts. I kept topping up the DEF fluid, but the error persisted. Have you checked the fuel efficiency lately? Mine dropped noticeably before the engine light came on.
