Unitronic UNIFLEX Hardware Kit (w/ Sensor) for 2.0 TSI EVO4 and 2023+ RS3

Unitronic’s UniFLEX Hardware Kit includes all components required to make flex fuel integration as effortless as possible. Comprised of our proprietary UniFLEX ethanol device, a genuine Continental ethanol content sensor with all required fittings and harnesses, this kit allows for true plug and play installation.

UniFLEX is also Bluetooth® enabled, allowing for wireless connectivity with iOS and Android mobile devices using the Unitronic UniE85 Manager App.

Unitronic E85 Manager is available for download on the App Store and Google Play Store.

NOTE: While this kit works with all 2.0TSI EVO4 vehicles, only the MK8 GTI is currently supported with FLEX enabled ECU Software. MK8 Golf R and 8Y S3 FLEX enabled software support is coming very soon.

NOTE: It is strongly recommended to use the UniFLEX Bracket for best experience.

NOTE ON SOFTWARE: Unitronic FLEX Enabled ECU Software is required and not included.
