I have a 2014 q5 tdi. I just had the dealer change the oil. I drove it home about 10 miles & the dash displayed to add a quart. I added the quart. Drove it a few more days. Then it said add a quart. I got another quart, but checked the oil level on the display this time. It showed no oil. I added 1 quart and it came up to the minimum level. I called the dealer & this time they wanted me to drop it off & then changed their mind and sent a tow truck to get it. They said it was possible I was overfilling it & a sensor was bad. I'm thinking they forgot to put oil in it. Any ideas what to do, or if this is even possible? I drove the car a little over 100 miles on the one quart I added.
