driving my 2013 A4 with 41,800 miles and have oil changed regularly every 15K as called for, yesterday while driving on a road trip had driven about 60 miles and the Turn Off Engine appeared and then the Oil Light Indicator came on ,stopped the car ran a MMI scan and it told me to Please Drain Oil , went to check oil and have no dip stick, panic attack and drove the car home ,went out this morning and ran the scan and same message came up, Question : Should I have it towed to dealership or attempt to drive, and has anyone had anything like this happen. I plan on calling dealership tomorrow. Just want to know if anyone has any idea what is going on as I cannot check oil and now it reads There is currently no information about oil level. The oil level indicator that shows max-min bar never showed when I ran scan to show me if it was low or not. Hope to hear back thanks.
