Overview
Enable E85 flex fuel tuning on your Audi 3.0T Gen 2 CREC engine with this precision-engineered ethanol content sensor mount. CNC-machined from aluminum, this mount allows you to install an ethanol content sensor directly into your fuel system, delivering real-time ethanol percentage data to your ECU for optimal flex fuel tuning. Compatible with 2015–2018 C7 A6, A7, A8, and Q7 models equipped with the CREC engine code.
E85 flex fuel tuning requires knowing the exact ethanol content of your fuel, as pump E85 can vary from E51 to E85 depending on season and location. This sensor mount enables the ethanol content sensor to read alcohol percentage in real-time, allowing your tune to continuously adjust fueling and timing for optimal performance and safety on Gen 2 CREC engines. Professional installation and a flex fuel tune are required.

Frequently Asked Questions
Is this mount compatible with Gen 1 Audi 3.0T engines?
No. This mount is designed exclusively for Gen 2 CREC engines. It is not compatible with Gen 1 Audi 3.0T engines.
Does this kit include the ethanol content sensor?
No. This kit includes the sensor mount and fittings only. The ethanol content sensor and ethanol sensor hardlines are sold separately.
Why do I need an ethanol content sensor for E85 tuning?
Pump E85 can vary significantly in actual ethanol content — typically ranging from E51 to E85 — depending on the season and region. An ethanol content sensor reads the alcohol percentage in real-time so your ECU tune can dynamically adjust fueling and ignition timing for safe and optimal performance regardless of blend.
Which Audi models is this mount compatible with?
This mount is compatible with 2015–2018 Audi C7 A6, A7, A8, and Q7 models equipped with the 3.0T Gen 2 supercharged TFSI engine (CREC engine code).
Is professional installation required?
Yes. Professional installation is required, along with a proper flex fuel tune from a qualified tuner. Incorrect installation or operation without an appropriate flex fuel tune can result in poor performance or engine damage.
