Help No Bargraph Reading...

[Mini KEG]

I am new to this water injection idea. I recently purchased an 06 R53 with HFS-6 already installed. While driving the Bargraph doesn't change. I completed a manual test and it sprays fine. The Bargraph shows it is spraying during manual test. The "B" is not lighting up while driving so it isn't falling in the fail-safe window. If anyone can help me out that would be much appreaciated.

Thank you
