Have a 2020 A3 and bought the Carista app to see if it can do some mods I want without buying VCDS. Was going to get OBDEleven but I heard Carista is good so I tested it.
Primary goal was to have Oil Temp display, adjust Virtual Cockpit color theme, enable more rear power through haldex, and disable Auto start/stop.
Things I was able to do that I enjoyed:
- Increase Traction Mode (More Power to the Rear Wheels)
- Locks the door if all doors are closed and key is outside (THIS IS THE BEST ONE)
- Changed throttle response to Direct which has a linear feel. Definitely enjoy this throttle response over the stock gradual setting.
- Can turn off DRL by placing it on the off position. Turns on by being placed on Auto (I like to call this mode Black Out mode)
- Scandinavian DRL (Rear tailights also on)
- Gauge needle sweep (This looks eh on Virtual cockpit)
- Enabled developer mode for Virtual Cockpit (I have no idea what I can do through this)
- Can change Audi logo on VC and MMI startup. There were 8 types, Type 2 being the S3, Type 5 being the RS3 and Type 7 being A3 Quattro. Couldn't see the difference between the other types. I kept mine on 7 because I'm not about misbadging my car.
I couldn't get the oil temp display to work and the DIS display. Guessing it's because of VC. Was really hoping to get adjustable color settings on VC but I guess it's not available for 2020 A3s. Same with the start stop feature :( It also doesn't have live data so you can't see gauges or boost which I guess some other apps can. The diagnostic portion worked well and I liked I was able to see the Launch Control count in services. You can also release your Emergency parking brake for service.
Overall for 30 bucks and a 10 dollar 1 month membership Im pretty happy with the changes. I have 29 days left so if you're in the SD area feel free to hmu and I can code your car for free.
