Questions about this file
Is this original file compatible with my Volkswagen BEETLE?
Compare the hardware number (03C906026D) and the software number (3454) with the identification your tool reads from the ECU. The software number must match; a different hardware revision usually means a different file. Identify the controller by the hardware and software numbers printed on its label or reported by your reading tool.
