Operations performed 3

  1. DPF OFF automated · solution rev 13 · ~5 min

    Deletes the diesel particulate filter (DPF) system in software; if the vehicle has AdBlue, it must be deleted first.

  2. EGR OFF automated · solution rev 10 · ~5 min

    Disables the exhaust gas recirculation (EGR) system.

  3. REVLIMIT automated · solution rev 1 · ~20 min

About this project

Bosch EDC17 is a widely used common-rail diesel ECU generation (Euro 4–6) with DFES fault-code tables. This unit is fitted to VW - AUDI - SEAT - SKODA - PORSCHE Car vehicles. Project #17764 was completed automatically by the ECUHARD file service for a VW - AUDI - SEAT - SKODA - PORSCHE Car vehicle running software 04L906026GK 9971 04L907309R.

Frequently asked questions

What was done to this EDC17C74 file?

Operations performed: DPF OFF, EGR OFF, REVLIMIT. The modified file was checksum-corrected and delivered ready to flash.

What is the software version for this EDC17C74 file?

This project is for EDC17C74 with software numbers: 04L906026GK 9971, 04L907309R. The same operations apply to other vehicles running the same software.

Can I get the same tuning for my VW - AUDI - SEAT - SKODA - PORSCHE?

Yes. Sign in, upload your original ECU file (EDC17C74 or any supported ECU), choose the operations you need and our automated system prepares the file, usually within minutes, 24/7.

I read my ECU with a different tool — will the tuning fit my file?

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.

I have an OBD read — can you tune it, or do I need a bench/boot read?

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.

I read boot mode with KTAG / bench with Flex / bench or OBD with Autotuner — which read do I upload?

Any of them. Upload the file exactly as your tool saved it (EDC17C74 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.

Do you need the full backup (EEPROM, other sectors)?

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.

How can I be sure the result will be compatible with my ECU?

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.

What other operations are available for EDC17C74?

STAGE1 (10 EUR, automatic, 41 ready solutions for this file size); STAGE2 (40 EUR, automatic, 8 ready solutions for this file size); STAGE3 (200 EUR, automatic, 1 ready solution for this file size); ADBLUE OFF (5 EUR, automatic, 34 ready solutions for this file size); LAMBDA OFF (5 EUR, automatic, 16 ready solutions for this file size); DECAT (5 EUR, automatic, 10 ready solutions for this file size); NOX OFF (5 EUR, automatic, 21 ready solutions for this file size); VMAX OFF (5 EUR, automatic, 21 ready solutions for this file size); TVA OFF (5 EUR, automatic, 15 ready solutions for this file size); FLAPS OFF (5 EUR, automatic, 15 ready solutions for this file size); STARTSTOP OFF (40 EUR, automatic, 4 ready solutions for this file size); IMMO OFF (50 EUR, automatic, 5 ready solutions for this file size); WATERPUMP OFF (5 EUR, automatic, 11 ready solutions for this file size); DTC OFF (10 EUR, automatic, instant); REV ORI (10 EUR, engineer-assisted, on request). Prices are per file.

I have a EDC17C74 file — how can I get it done?

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.

Do I need to send my original file?

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.
