Adblue

Hi all
My Q2 30 tdi shows 4500 miles for the adblue on the onboard computer. On this basis I bought 10 lts at around 4300 miles. The mileage has now gone beyond 4500 and no top up warning has appeared despite the display still showing 4500. Am I misunderstanding something ? When can I expect the warning to appear ? I believe that I can't top it up until the warning comes on or else the system won't know that more has been added.
Appreciate any advice you can give.
Thanks

Thanks for the advice. While I understand what you are saying my car does a regen fairly often so I assume this is an indication of the DPF blocking. Can't understand why the car gives you the mileage for a top up and then ignores it ?
