Luis1914 Posted December 20, 2017 Share Posted December 20, 2017 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....!!!

Bigdave1230 Posted December 21, 2017 Share Posted December 21, 2017 Does the radio/mmi still work or is the entire electrical system dead? I think if the key was faulty the ignition lights would still come on but the immobiliser would stop the car starting Quote Link to comment Share on other sites More sharing options...
Envy Posted December 22, 2017 Share Posted December 22, 2017 Sounds like primary power issue to me - battery is new so that can be dismissed. Some Q7 have reported power grounding issues - check earthing straps. If your central locking works then that would suggest power is good and primary functions are working. Do you have both keys? Same issue with both? As asked above - does radio come on without ignition on? Quote Link to comment Share on other sites More sharing options...
