Section tuning-installation intro
TDI Tuning tuning boxes have been engineered to make installation as simple as possible, without the need for any mechanical expertise or specialist tools. Our tuning boxes are plug-and-play to make the benefits of tuning instantly available. This also means that removing the tuning box is just as simple.
This guide shows the process of installing one of our tuning box's. When you purchase a tuning box you will receive illustrated instructions for your exact vehicle so the process may vary slightly.

Once the tuning box is in place turn on your car, and your phone’s Bluetooth. Open the TDI Tuning app and connect to your tuning box.
Follow the on-screen instructions to pair with your CRTD4 tuning box and begin using the app’s features. You will need your 6 digit PIN code, which can be found on the tuning box itself or in your owner’s manual.
Once paired you will be able to set your tuning box’s performance setting, customise the app, and connect with other tuners.
