Description

Take your Volkswagen or Audi to the next level with the COBB Flex Fuel Upgrade Kit, designed for MK7/MK7.5 GTI and Golf R, Jetta GLI (A7), and Audi A3/S3 (8V) models. This complete kit adds full Flex Fuel functionality, giving your ECU real-time ethanol content data to optimize performance and reliability on E30 blends.

The kit includes everything you need for a fast, clean install:

OE-quality ethanol content sensor with powder-coated aluminum mounting bracket
Custom COBB wiring harness and fuse tap harness
Quick-connect fuel fittings for OEM-level integration
A pin locator template and tool for foolproof ECU wiring

Mounting cleanly to the passenger side engine mount, the sensor instantly transmits ethanol levels to the ECU. It works seamlessly with COBB’s Accessport-delivered Flex Fuel OTS maps or a custom tune, making it easy to start running ethanol blends (up to E30) for improved power, drivability, and knock resistance.

This kit is perfect for drivers using COBB’s Stage 1 OTS maps or looking to prepare for future tuning stages. Any ethanol blend exceeding E30 will trigger a custom COBB DTC (COB13) to protect your motor, with power safely reduced until ethanol content is lowered and ECU reset.

USDM models only. Requires COBB Flex Fuel OTS map or Panda Motorworks custom tune.
