I got a flat yesterday on my 2018 S4 with the 19" black optic package. There was a spare tire in the trunk but no patch kit or jack. Are these cars supposed to come with some way of installing the spare tire? I leased this car from a very large Audi dealer in the Midwest and have had issues with them before cutting corners during our negotiation. Is it possible they took it out of my car to put in another? Thanks for your help!
