One problem related to engine burning oil has been reported for the 2015 Audi A3. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2015 Audi A3 based on all problems reported for the 2015 A3.
Excessive oil consumption car has 2,300 miles left to the 10k oil service check change and showing low oil. This is not normal Audi is trying to say to just top off the oil, yet excessive oil consumption will cause the car to need engine replacement earlier than it should at about 70-80-100k miles at best. There are many complaints and a class action that involved this issue but they refuse to do more than change oil and check for leaks when they know it is due to defective parts and I am under a certified warranty until October 2019.
