How to check adblue level audi q7?

The diesel exhaust fluid, also known as DEF or the trade name AdBlue, is an important part of Your AudiQ7's fuel system. Unfortunately, there's no way to check Your DEF level between fill ups. The recommended procedure is to top off the fluid every 10,000 miles at scheduled maintenance. Your Q7 should give You a 1500 mile warning if You're about to run out of diesel exhaust fluid, so while the situation isn't ideal, You at least have some type of indicator when You're about to run out. It would be awfully convenient if there was a way, but unfortunately You're stuck with the circumstances You're given. Just make sure You top off regularly, and that's the best You're able to do.
