Robert.

I believe the car will warn you when Adblue needs to be topped up.

Do look through this forum's history for knowledge of the potential Adblue problems you may face in the future, and how to resolve them. You may get the impression there that Adblue is a disaster waiting to happen, and indeed it can be if left to its own devices, but with the right care it can be a trouble-free system.
