2015 VW GLI gen 3 ea888.3

I love this app. I knew I wanted to change a few characteristics of how the lights operate, windows operate, and the locking procedure for the car. I was able to change much more than I anticipated through the app and the supporting Carista adapter. Recently this new update came out, claiming that you can change the volume for the stupid sound aktor device Vw/Audi uses, and while most features added to the app work with my car, this one doesn’t seem to even show up as an option to change. I’m even able to change the torque steer compensator; so while the app has tons of features, some may claim to be compatible with your car but not functional. I’ll do 5 stars if the devs can fix the issue or come out and specify which models of Vw/Audi get the sound aktor ability.

EDIT: function doesn’t apply to my vehicle. 5 stars added.

Does what it says, but only minimal usefulness

First, it works perfectly. For customization, though, while there are probably a hundred different options I can customize, most are options I could already customize right from the car’s menus. They also include a lot of useless options that nobody would ever care or want to change. That said, I bought it to fix two issues and it was able to solve one beautifully. I used it to shut off the engine auto-off when stopped at a stoplight. For that alone, it was worth the price of the module (and I accomplished that with the free trial, so no cost for the app). The other issue I was hoping it would fix was the unreasonably loud and long warning dings when I open the car door with the car running. Sadly, turning that off (or even adjusting the volume) isn’t an option. Either way, it was worth the cost for the one problem it solved, so I can’t complain. It may be great for the diagnostic tools, but I have no need for that, so I can’t comment.

Great App!

I’ve been updating control modules on my vehicles for years with Ford and Mopar vehicles and always had to use the wired OBD adapter plugged in to my laptop. I’ve always been an Apple guy so in order to use the software I had to either run bootcamp or virtual windows on my MacBook. It’s been a necessary evil to accomplish the changes I wanted to make.

Carista absolutely blows that away. I never knew this type of setup existed and thought it was too good to be true when I stumbled across it on a forum. Coming from how I’ve always had to do things in the past I’m extremely happy with this product.

Lots of customization options and based on the current beta they have plenty more customizable options coming soon!
