What You Should/Must Know About Audi A5 B8

I’ve just acquired a 2014 Audi A5 Cabriolet Premium Plus with Navigation and sport package. From 2008-2017 it’s B8. I’m listing all the things we need to know about our A5 B8 (I think it’s the same for coupe also).

  • : I left the interior lights on for 2 days and the battery went down to 9V. The key fobs don’t open/close doors, nothing. The battery is located under the spare tire, there are positive and negative poles in the engine bay, so don’t charge or jump the battery from the battery itself, must use these 2 poles in the engine bay. The original battery is AGM so charge with the setting accordingly.
