apollo Posted October 24, 2020 Share Posted October 24, 2020 Hi guys My sons 2013 A5 has a problem with the MMI unit. It starts up then shuts down within a few seconds. I understand I can use a optical loop to check the components to hopefully find which one is faulty. Can someone tell me where they are located. I have found the unit it the boot but don't know where the others are located. Quote Link to comment Share on other sites More sharing options...
