MED9.1 5K0907115K 0010 1037516494 0261S02829

It is the untouched factory software read from the ECU before any modification. Tuners keep it as a backup and use it as the base for Stage 1/2, DPF/EGR/AdBlue off or DTC removal.

Match by the software number (5K0907115K 0010, 1037516494, 0261S02829) printed on the ECU label or read by your flashing tool. The software number must be identical.

The file costs 20 EUR (one-time). Sign in, open this page and click Buy & Download — the file is sent to your e-mail instantly and stays in your account. An invoice is issued automatically.

Different tools and modes (OBD, bench, boot) read different memory ranges, so an archive file may not be byte-compatible with your read even when the software number matches. Our platform has a REV ORI (revert to original) module: upload the file you read from your own car — no matter which tool or method was used (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot) — and it repairs every modified area back to the stock values and returns your own file. Because it works on your own read, a compatibility problem is impossible. REV ORI costs 20 EUR, the same as this original file.

Compare the software number (5K0907115K 0010, 1037516494, 0261S02829), the read type (see above) and the file size (2.00 MB) on this page with your own read. If they differ, do not guess: Our platform has a REV ORI (revert to original) module: upload the file you read from your own car — no matter which tool or method was used (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot) — and it repairs every modified area back to the stock values and returns your own file.

You do not need to match the tool. Our platform has a REV ORI (revert to original) module: upload the file you read from your own car — no matter which tool or method was used (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot) — and it repairs every modified area back to the stock values and returns your own file. Because it works on your own read, a compatibility problem is impossible. REV ORI costs 20 EUR, the same as this original file. Buy this original file when you need a stock reference or a backup for the same software; use REV ORI when you want your own ECU back to factory.

No. The archive keeps only the software-related part of the ECU: the maps area — the internal flash and/or the external flash, depending on where the software lives in that ECU (this varies by ECU type). EEPROM and other memory sectors are never included, so the file is not a full backup. For a full restore of your own unit, upload your own read to the REV ORI module.

Check that the software number is identical, then compare read type and file size with your read. If anything differs or you are unsure, use the REV ORI module on your own file — it is always compatible — or contact us via WhatsApp or e-mail with your read details before buying.
