I bought this 2014 Audi S7 one year ago with 116kkm. I don’t do lots of driving so I’m at almost 124kkm. It’s been an interesting ownership experience for me since acquiring the vehicle from a BMW dealership, I have a learned its service history. There has been a lot of work done on the car so perhaps I am lucky to be owning it at this point and hope the worse has already happens and it clea sailing. Previous repair orders that I got from the local Audi store dealt with many items. And Include: the whistling nose that comes from the oil separator, the fuel door actuator, two times, all motor mounts, front and rear control arms et al. I also learned that the car had an ECU and TCU tune using Unitronix software. I contacted the company who did that tune and got a pile of info as It also has upgraded sway bars and wheel spacers. The car was originally ordered new with Audi exclusive paint as Daytona grey pearl which was not available on the S7, but rather only on A7 or the RS7. I contacted the selling dealer and got the 2014 order guide to check out options and pricing at the time it was new. I also contacted Audi Canada corporate and got the build sheet on the car and learned the car was manufactured on May 5, 2014 making it one of the last of the C7’s. With this tcu tune, the car has a 5500 RPM launch and does so like a rocket. I believe it’s pushing a 1-4 mile at 11.5 territory with a 0 to 100 km an hour in the mid-threes although I haven’t tested it. Getting back to repairs done, I have also discovered that all 4 camshaft position sensors on one of the banks has been replaced. The brakes were recently done. On another repair order, I learned that the fuel pump, the one in the gas tank, was also replaced. The selling dealership also took care of two check engine light problems that occurred recently after purchase. This includes a new thermostat, which is very expensive, as well as a post catalytic converter oxygen sensor. Further My service experience includes the recall for the oil strainer, which I was told, was in decent shape and not plugged. The service advisor told me in cases where oil strainer damages, and then damages the actual turbos. My strainer was all intact, and as I said, not plugged . I also purchased pre-paid Audi maintenance package. This package covers three service Intervals, including two majors and one minor. They are to occur at around 120k I’m (major and just done) , 135k km and 150 K km. For these three services it only cost me $1595, prepaid. I also contacted uniTronic directly where they offered to transfer the file/information/account into my name for $150 transfer fee which I had not done as yet. If you think this review has a lot of detail you should see the spreadsheet I have made! OK I’m a bit OCD.

The 4.0 has returned for the 2022 RS7 model. It's only offered on the RS7 and not the S7. The 4.0 is a gem. I love my 2014 S7 it is a beast.
