MARELLI IAW 036906034GM 4MV

Operations performed: DTC OFF. The modified file was checksum-corrected and delivered ready to flash.

Each code is switched off in the ECU fault table, so it is no longer stored or shown by diagnostic tools.

This project is for MARELLI IAW with software numbers: 036906034GM, 4MV. The same operations apply to other vehicles running the same software.

Yes. Sign in, upload your original ECU file (MARELLI IAW or any supported ECU), choose the operations you need and our automated system prepares the file, usually within minutes, 24/7.

Yes. Every operation is applied to the file you upload — your own read from your own car — so the tool and the read mode do not matter: the modifications are located by content, not by a fixed file layout. If your file was modified before, our REV ORI (revert to original) module repairs every changed area back to the stock values first — no matter which tool or method read it (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot) (10 EUR). A compatibility problem is therefore impossible.

An OBD read is fine as long as it contains the software area (maps). Upload it; the platform detects the ECU and software number and shows which operations are available for your file. If the read is partial and an operation is not possible on it, you will see that before paying.

Any of them. Upload the file exactly as your tool saved it (MARELLI IAW reads are supported in OBD, bench and boot form). The system works on your own read, so nothing has to be converted or matched to a different device.

No. Only the software-related part of the ECU is used: the maps area — the internal flash and/or the external flash, depending on where the software lives in that ECU. EEPROM and other memory sectors are not needed and are never modified. Keep your full backup for yourself as a safety copy.

Because the file returned to you is your own read with only the selected areas changed and the checksum corrected, it flashes back with the same tool and method you used to read it. The software number stays the same; nothing else in the file is touched.

STAGE1 (10 EUR, automatic, 5 ready solutions for this file size); STAGE2 (40 EUR, engineer-assisted, on request); EGR OFF (5 EUR, automatic, 5 ready solutions for this file size); LAMBDA OFF (5 EUR, automatic, 7 ready solutions for this file size); DECAT (5 EUR, automatic, 1 ready solution in library); VMAX OFF (5 EUR, engineer-assisted, on request); POPBANG (20 EUR, automatic, 3 ready solutions in library); IMMO OFF (50 EUR, automatic, 1 ready solution in library); CHECKSUM OK (1 EUR, automatic, 1 ready solution for this file size); REV ORI (10 EUR, automatic, stock file in archive). Prices are per file.

Sign in to the ECUHARD platform (solutions.ecuhard.com), upload your ECU file, select the operations you need and confirm. Automatic solutions are delivered within minutes, 24/7; engineer-assisted operations are prepared by our tuning team. Each file is checksum-corrected and an invoice is issued automatically.

Yes. The file is linked to ECM Titanium driver S14_D4AD (SEAT CORDOBA). Matched: the software range is identical to the driver reference. The driver tells the software where the maps of this ECU software are, so tools that use ECM drivers, including the ECUHARD Tuning Editor, can open the maps automatically.

Yes — upload the stock read of your ECU. If you do not have it, our original file archive may have a matching file by software number.
