Hi , I did tell them that the battery had been flat , I'm not sure if they tested it. They said they suspect the mmi has gone down during jump start. But said they want £250 to further investigate which id rather avoid if i can as they said they still might not find anything. They did a forced reboot and still didn't find anything.
Hi my car was off the road for a few months. It needed jump starting. But now my MMI won't work , theres Just a blank screen .I Took it to volcksmaster but they couldn't find anything on there diagnostic computer? Any one had this problem or got any solution? Many thanks
