This dual-version ECU file set is tailored for the 2008 Audi A4 2.0 TDI CR with CAGC engine and Bosch EDC17_CP14 ECU. It includes both Stage 1 and Stage 2 NO DPF calibrations. The Stage 1 remap improves drivability and mid-range torque, while the Stage 2 version fully disables DPF-related routines for off-road use. Optimized for the 6-speed manual transmission, both files are dyno-tested and ready for performance applications.
