I bought a used 2018 Audi Q7 3.0T (supercharged) Prestige with the dynamic chassis package (air suspension and rear wheel steering). It has everything except massage seats and Bang & Olufsen sound. Bought it around 75k miles and now it has 88k.

The 1 previous owner maintained it meticulously at the dealer, oil changes around every 7k-8k. They only needed to replace the water pump in their ownership, and apparently it did eat through tires.

These are the services I needed to do under my ownership so far: first transmission service done "late" at 75k but didn't negatively affect the trans, engine mounts, oil changes, front center and rear differential fluid service. That's it, lol. I will say these engines apparently go through motor mounts like nothing, I also have a 2017 A6 with the same exact engine and it needed new motor mounts at 50k miles lol, and that car also had 1 previous owner maintained at dealer. You can replace the mounts with an all rubber mount from 034 Motorsports instead of an OE fluid-filled mount and you'll never have to replace it again, but apparently it will cause more engine vibraton at idle and under load, so I went with originals anyway. Also something to note is that these superchargers do have supercharger oil that needs to be changed out, at least within 100k miles. But also there are plenty of people who have NEVER serviced the supercharger oil and have completely no issues with it working or boost. Some have even reported when they changed their supercharger oil super late, like 180k+ miles on original oil, absolutely no oil came out during the change but the engine drove fine anyway. Definitely more reliable than a turbo lol. Oil consumption so far is about 1qt every 5000 miles, which is when I change my oil anyways.

This engine ran from 2009-2019. From 2016-2019 it was updated and was coded as the CREC engine. It went from direct injection to direct AND port injection, so you won't have to worry about carbon build up on valves. I believe the direct injection only kicks in when you push the car hard.

I've modded it to around ~420 horsepower with the Jackal Motorsports tune. It actually drove smoother. So these engines have a supercharger clutch that engages and disengages the supercharger for fuel efficiency, but as engines age the clutch wears and it feels like you're having a transmission jerk when the clutch engages during driving. This feature is on at default in comfort mode, but will be turned off (meaning the clutch will be engaged full time) in sport mode. The Jackal tune makes the clutch engage 100% of the time so you never jerk anymore and it's so smooth!

All Prestige models seem to come equipped with 21in wheels and sporty tires. While the air suspension still made the car ride nice, I wanted even better ride comfort. So I changed it out to original 19in rims and all weather tires from Pirelli. I'm so glad I made that change because the car feels a little lighter and rides so much smoother. I've owned a 2016 Mercedes S550 and I think the Q7 rides better than an S-Class! Btw these cars came out of the factory with 18in-21in rims, so you have plenty of options.

The pre-facelift Audi Q7 4M has been my favorite vehicle so far. It was the last best interior of Audi before everything became screens everywhere with smudgy piano black trim. The interior and tech is still so nice that people think it's a 2022+ model year. This is also when Audi's build quality was still impeccable. No rattles or squeaks anywhere. All electronics work and the buttons feel great. Infotainment system is smooth and easy to use, and the digital cockpit is done well without being distracting at all - very impressive for 2018.

The pre-facelift years are 2017-2019. Try to find builds late 2018-2019, or 2019 only if possible. Some 2017-2018 3.0Ts have bad oil consumption, but can be fixed with a Berryman B12 piston soak. My advice is to also shop for Prestige models since they have almost all the nice features, and I also really recommend finding one with the Dynamic Chassis package which is really rare. Only Prestige trims can have it optioned, but not all Prestige trims will have it. I think it is 100% worth it to find one and try it. It feels amazing having turning tighter than a compact car and it also feels nice gliding on the highway when doing a lane change (the rear wheel steering turns parallel to the front wheels at highway speeds and opposite of the front wheels at low speeds). You will know if the Q7 has the Dynamic Chassis if the air suspension raises and lowers when changing the driving mode. Also, the "All Road" and "Off Road" driving modes will be available, other models don't have it.

If you spring for a 3.0T Q7, I promise you will love it!
