This part is legal under the provisions of EPA’s Anti-Tampering Policy. COBB Tuning has established a reasonable basis (testing results) via SEMA Garage Emissions Certification that verifies that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and EPA’s Anti-Tampering Policy.


Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending. Once testing is complete with California, and an EO number is issued, this product will be updated to 50-state legal status.



The Stage 1 + Flex Fuel Power Package for Volkswagen (MK7/MK7.5) GTI, Jetta (A7) GLI, AUDI A3 (8V) consists of Accessport for Volkswagen AP3-VLK-002, High Flow Filter, and the Flex Fuel Upgrade Kit.

The Flex Fuel Upgrade Kit for VW/Audi vehicles makes adding Flex Fuel functionality to your vehicle and existing ECU a breeze. This kit consists of an ethanol content sensor with bracket, bespoke wiring harness, a fuse tap harness, quick connect fuel fittings, and a super slick ECU pin locator template and pin tool. We've bundled everything you need to get on corn in minutes!

This kit seamlessly integrates with the factory ECU and the provided pin locator tool takes the guesswork out of the equation. The OE quality ethanol content sensor is secured to a bespoke powder coated aluminum bracket. Fuel is then fed to and from the sensor with pre-made fuel line with OE quick disconnect.

The ethanol content sensor is mounted on the passenger side engine mount and instantaneously reads the ethanol level in the fuel multiple times per second before sending that to ECU to be used by an Accessport-delivered Flex Fuel calibration.

Included as a part of this release are a set of COBB Off The Shelf Maps that are specifically calibrated for use with the Stage 1 package. All maps have been optimized for use with a completely stock fuel system, aside from the installed COBB Ethanol Sensor Kit. As such, they are configured to produce maximum power at an E30 blend. Any ethanol concentration beyond that level will result in a custom COBB DTC (COB13) and a reduction in power. Reducing the ethanol content to E30, or lower, and resetting the ECU will clear the DTC.

Upgrade Kit is for USDM models only and requires use of either COBB Flex Fuel OTS map or custom tune from an authorized protuner.
