hi people im new here, and im having an issue with my Audi Q7 2007 3.0, the last night i came home like every day and i turned off the car and the next morning i try to start it and i had no light on the dashboard, i already check all the fuses removing one by one to make sure there is noting wrong with them, then i replace the battery and still the same issue, i read in a web page that in some times this specific cars gives that issue due to the car key, but here is no a place that i can test the key, i will appreciate if someone knows something about this issue... thanks....!!!
