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 MERCEDES Car vehicles. Project #20561 was completed automatically by the ECUHARD file service for a MERCEDES Car vehicle running software CR41-626-48R2-205WA-100KW-Ch4-EU6SCR_LH-C1_INJ554_KT_NOxB-002_ME1846 10SW045800. Disabled fault codes: P0401, P0402, P0403, P0404, P0407, P0408, P0409, P040B, P040C, P040D, P040E, P040F, P041A, P041B, P041C, P041D, P041E, P042E.

Frequently asked questions

What was done to this EDC17C66 file?

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

Which fault codes (DTC) were disabled?

P0401 (Exhaust Gas Recirculation Flow Insufficient Detected); P0402 (Exhaust Gas Recirculation Flow Excessive Detected); P0403 (Exhaust Gas Recirculation Control Circuit); P0404 (Exhaust Gas Recirculation Control Circuit Range/Performance); P0407 (Exhaust Gas Recirculation Sensor "B" Circuit Low); P0408 (Exhaust Gas Recirculation Sensor "B" Circuit High); P0409 (Exhaust Gas Recirculation Sensor "A" Circuit); P040B (EGR Temperature Sensor "A" Circuit Range/Performance); P040C (EGR Temperature Sensor "A" Circuit Low); P040D (EGR Temperature Sensor "A" Circuit High); P040E (EGR Temperature Sensor "A" Circuit Intermittent/Erratic); P040F (EGR Temperature Sensor "A"/"B" Correlation); P041A (EGR Temperature Sensor "B" Circuit); P041B (EGR Temperature Sensor "B" Circuit Range/Performance); P041C (EGR Temperature Sensor "B" Circuit Low); P041D (EGR Temperature Sensor "B" Circuit High); P041E (EGR Temperature Sensor "B" Circuit Intermittent/Erratic); P042E (EGR "A" Control Stuck Open). Each code is switched off in the ECU fault table, so it is no longer stored or shown by diagnostic tools.

What is the software version for this EDC17C66 file?

This project is for EDC17C66 with software numbers: CR41-626-48R2-205WA-100KW-Ch4-EU6SCR_LH-C1_INJ554_KT_NOxB-002_ME1846, 10SW045800. The same operations apply to other vehicles running the same software.

Can I get the same tuning for my MERCEDES?

Yes. Sign in, upload your original ECU file (EDC17C66 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) (20 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 (EDC17C66 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 EDC17C66?

STAGE1 (20 EUR, automatic, 19 ready solutions for this file size); STAGE2 (80 EUR, automatic, 4 ready solutions in library); STAGE3 (400 EUR, engineer-assisted, on request); DPF OFF (10 EUR, automatic, 16 ready solutions for this file size); EGR OFF (10 EUR, automatic, 15 ready solutions for this file size); LAMBDA OFF (10 EUR, automatic, 10 ready solutions for this file size); NOX OFF (10 EUR, automatic, 7 ready solutions in library); VMAX OFF (10 EUR, automatic, 5 ready solutions for this file size); TVA OFF (10 EUR, automatic, 5 ready solutions for this file size); FLAPS OFF (10 EUR, automatic, 5 ready solutions for this file size); STARTSTOP OFF (80 EUR, automatic, 1 ready solution for this file size); IMMO OFF (100 EUR, automatic, 1 ready solution in library); HOT START (40 EUR, engineer-assisted, on request); REV ORI (20 EUR, automatic, stock file in archive). Prices are per file.

I have a EDC17C66 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.
