Every operation below can be ordered for the same MD1CS004 file (diesel). Prices are per file in EUR; automatic solutions are delivered within minutes, engineer-assisted ones are prepared by our tuning team.

STAGE1 A performance tune that needs no mechanical changes and stays within the factory safety limits. automatic, 24 ready solutions for this file size · ~15 min 60 EUR
STAGE2 A performance tune for vehicles with hardware upgrades such as a downpipe, intercooler or intake; DPF/EGR delete is a separate operation. engineer-assisted, on request · ~60 min 120 EUR
ADBLUE OFF Disables the AdBlue (SCR) system in software; no AdBlue refills are needed afterwards. done in this project ✓
DPF OFF Deletes the diesel particulate filter (DPF) system in software; if the DPF and AdBlue (SCR) share one housing, AdBlue must be deleted as well. automatic, 11 ready solutions for this file size · ~5 min 30 EUR
EGR OFF Disables the exhaust gas recirculation (EGR) system. automatic, 10 ready solutions for this file size · ~5 min 30 EUR
LAMBDA OFF Disables the oxygen (lambda) sensors. automatic, 5 ready solutions in library · ~5 min 30 EUR
DECAT Disables catalytic converter efficiency monitoring and the P0420/P0430 fault codes. engineer-assisted, on request · ~5 min 30 EUR
NOX OFF Disables the NOx sensor. done in this project ✓
VMAX Removes the speed limiter (Vmax) or sets it to the desired value. automatic, 11 ready solutions for this file size · ~5 min 30 EUR
TVA OFF Disables the diesel throttle valve. engineer-assisted, on request · ~5 min 30 EUR
FLAPS OFF Disables the swirl flaps in the intake manifold. engineer-assisted, on request · ~5 min 30 EUR
HARDCUT Sets the engine hardcut (rev cut) point. engineer-assisted, on request · ~20 min 30 EUR
DTC OFF Permanently disables the fault codes (DTC) you select; you need to provide the P codes to turn off. automatic, instant 30 EUR
REV ORI Restores your modified software file to its original factory state. engineer-assisted, on request · ~120 min 30 EUR

About this project

Bosch MD1 is a current-generation diesel ECU (Euro 6) with advanced emission control. This unit is fitted to VW - AUDI - SEAT - SKODA - PORSCHE Car vehicles. Project #6004 was completed automatically by the ECUHARD file service for a VW - AUDI - SEAT - SKODA - PORSCHE Car vehicle running software 05L906022FT 2107 05L907309T.

Frequently asked questions

What was done to this MD1CS004 file?

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

What is the software version for this MD1CS004 file?

This project is for MD1CS004 with software numbers: 05L906022FT 2107, 05L907309T. 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 (MD1CS004 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) (30 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 (MD1CS004 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 MD1CS004?

STAGE1 (60 EUR, automatic, 24 ready solutions for this file size); STAGE2 (120 EUR, engineer-assisted, on request); DPF OFF (30 EUR, automatic, 11 ready solutions for this file size); EGR OFF (30 EUR, automatic, 10 ready solutions for this file size); LAMBDA OFF (30 EUR, automatic, 5 ready solutions in library); DECAT (30 EUR, engineer-assisted, on request); VMAX (30 EUR, automatic, 11 ready solutions for this file size); TVA OFF (30 EUR, engineer-assisted, on request); FLAPS OFF (30 EUR, engineer-assisted, on request); HARDCUT (30 EUR, engineer-assisted, on request); DTC OFF (30 EUR, automatic, instant); REV ORI (30 EUR, engineer-assisted, on request). Prices are per file.

I have a MD1CS004 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.
