This happened while I was driving an errand today. I checked fuses, battery and all looks good. Here is the scan report from my Launch scanner.

Inspection Report

Voltages are good from the battery.

Has anyone had this issue before?

I know "take it to the dealer" is an option. Looking for other input.

 

The problem was the battery. It wasn't apparent at first because the car operated fine but I'm guessing the voltages were causing issues even though the alternator was reporting good voltage. Once I left the car sitting, it wouldn't crank and had zero power so I replaced the battery. With this particular Q7 you need to do a battery reset or adaptation. I think some people can catch this early and avoid this scenario but I wasn't one of those.

With a scanner tool you can go into the guided functions and do the battery adaptation. This is where you give the information for the battery, amp hours, manufacturer, battery type and serial number. Once you apply this new information to the vehicle, shut it off for 30min and come back and start it up, this is what worked for me. All my gauges and LEDs are working fine now. Feel free to hit me up if you have any questions.
