Audi S3 – COBB tuning

COBB Tuning has been steadily increasing the quality and depth of support for the 2.0 TFSI powered cars in the Volkswagen platforms for a few years now. So the next big step in the evolution of our MQB support has begun with the official release of tuning and hard parts products for the 2015-2020 Audi S3!


The objective of COBB Tuning is to always provide the most complete tuning solution for every vehicle we support and the key to unlock that solution is the Accessport!

accessport_v3_audi_s3 The Accessport is the world’s best handheld OBDII engine management device.
Combining easy DIY use, advanced performance features, live data monitors,
with off-the-shelf and custom tuning options mean that the Accessport is designed to
accompany you and your car along every step of your Audi modification journey.


Nothing beats big results with little effort. In a matter of minutes, an Accessport can be installed to an Audi S3 in your very own driveway to make instant grin-inducing power gains! Straight out of the box, the Accessport will include the Stage1 map and several other useful non-performance maps. Plus, additional stage tunes will be available for upgrades as we further develop the platform in the future.



The Stage1 map produces huge gains in low-end torque and consistent horsepower throughout the entire power band. Flashing this map to your S3 is the best bang for your buck modification you will ever make to your car.

Non-Performance Maps

Anti-Theft Mode – This map will essentially disable the car until the map is changed back to a normal performance or stock tune. Perfect for leaving the car somewhere for an extended period of time. Just remember to have your Accessport handy when you go back to get it.

Valet Mode – It’s well known that nobody abuses a car more than when it doesn’t belong to them. So you can easily flash this Valet mode map if you need to leave your car somewhere that you might not trust. It will still drive but a strict speed limiter is applied, meaning even the naughtiest valet driver can’t hoon your ride.


The goal of the Accessport is to be a complete tuning solution. With the excellent dual-clutch S-Tronic transmission found in the S3, tuning the car wouldn’t be complete without improved transmission calibrations to support the additional grunt. Luckily the Accessport has that covered as well.

When we say “complete tuning solution”, that’s exactly what we mean. Some will be more than happy to enjoy the great improvements found in OTS maps and gradually modify their car as more parts and maps become available, but we also know that some can’t wait. So while all of you are happily purchasing new Accessports, our awesome network of authorized COBB Protuners are applying updates to their AccessTuner Pro custom tuning software to be ready for whatever modifications you want to make to your S3.
