About FRF / SGO files

FRF and SGO files are the original flash containers used by Volkswagen, Audi, Skoda, Seat and other VAG group vehicles. They contain the factory software for engine, gearbox, comfort and other control units and are flashed over OBD with ODIS, VCP, ODIS-E or compatible VAG programming tools. Use them to update a module to a specific software version, to recover a unit after a failed flash, or to extract the original calibration for tuning work. Every file is listed by software number and version, so you can pick exactly the container your dealer scan tool or workshop software requires. All FRF and SGO files are unmodified originals. Pay securely and download instantly; the file stays available in your account. Missing a version? Send us a request and we will source it.

FRF / SGO files: frequently asked questions

How do I flash an FRF or SGO file?
FRF and SGO containers are written over OBD with ODIS, ODIS-E, VCP or another VAG-compatible programmer. The container includes the software plus the flash procedure, so the tool handles checksums and sessions. Make sure the vehicle battery is supported by a charger during the whole flash.
How do I know that a file matches my ECU?
Compare the hardware number and software number printed on the ECU label (or read by your tool) with the numbers in the product title and attributes. They must match exactly; a different software version is a different file. If you are not sure, send us the numbers and a photo of the label before buying.
How is the file delivered?
Immediately after payment the file appears in your account under Downloads and a link is sent by e-mail. The file stays in your account, so you can download it again later. Files are delivered as ZIP archives containing the read exactly as it came from the unit.
The file I need is not listed. Can you supply it?
Yes. Use the file request form or e-mail us the vehicle, ECU model, hardware and software numbers. Most requests are sourced within a few hours, and the file is then added to the shop for you to purchase and download.
