Just curious how many diesel car owners have had their AdBlue caps replaced (for free by Citroen) and how many know about this. As far as I can work out they identified that there's a design issue with the system and brought out a vented version of the cap (in 2018?) to reduce pressure which in turn prevents the injector failing prematurely (but I might be making this up).

As far as I know there is no way to check how much AdBlue is in the tank. It is not a service item so it is very unlikely to be topped up at a service. The capacity is ~17L, and it is reckoned to last 14,000 miles, so it probably won't last your 16,000 miles service interval.
Q. How large is the DEF tank on my machine? A. Several tank sizes will be specified based on machine application and duty cycle. The specific size also ensures a diesel fuel to DEF fill ratio of 1:1 (that is, one DEF tank refill to each fuel tank refill) is met. Generally speaking, the size of the DEF tank is about 10% the size of the diesel
