 Good news! Launch X431 ECU & TCU programmer new V10.51 version software added Benz VGS4 bench mode without removing the shell as previous version. Here iecutool.eu will show how to erase/virgin and clone Benz VGS4–0-NAG2 4-speed transmission gearbox TCM on bench mode. This step-by-step guide helps technicians safely erase transmission control data and prepare the module for programming or replacement. In Launch X431 ECU software, quick search VGS4 and choose C-class-> VGS4–0-NAG2 TCU and Bench mode. Check the wiring diagram. Connect VGS4 TCM with Launch X431 ECU programmer following the diagram or use the Benz solder free gearbox connector. Read TCU informtaion. Read EEPROM data and save original gearbox data. Disconnect original VGS4 TCM. Change to a new ECU connection to write data. Connect a donor VGS4 TCM with Launch X431 ECU programmer . Choose Benz C-class — VGS4–0-NAG2 TCU — Bench mode. Read ECU info and eeprom data. Back up the eeprom data of...

 Foxflash new user report: It’s an Isuzu Dmax 2007 3.0d. Foxflash read it via obd on bench. DCM6.2 Delphi ecu Mpc56x Used multimultional adapter without benchbox. Obd protocol read ok. Took 1hr to read. Awaiting for a 5–6 amper power supply for writing to be safe. You can also use OTB adapter on this or gt100 diagtable.

It’s a BMW 3D 184hp with Bosch EDC15C4 ECU. Tried Foxflash Full mode but not working(connected everything as shown, measured cables, resistors, outputs everything with multimeter and it’s 100% fine but still no connection) — ERROR SEND WAKE. Simulated OBD on BENCH via K-LINE ok. READ — 5 min WRITE — 2 MIN ONLY FLASH PARTIAL READ!! Checksum with winols. If need to do it via full system mode, need to fix the colored rainbow cable! Problem is rainbow cable inverted, you need to fix the cable.

 Here is the real user’s working experience on VW Passat B7 EDC16CP46 ECU cloning using foxflash : It’s a VW Passat B7 2013 CFFB with Bosch EDC17C46 ECU. The ecu was broken, car didn’ t start, reading on bench was not working. The car wouldn’t start, some water had gotten into the ecu through the plastic plug. The car could be diagnosed on the ecu but there was no error. I tried to read the ecu in the bench but every time it told me to disconnect and reconnect the power and nothing happened. I had another ecu with the same part number from a Passat CC, so I backed it up in the bench. I saw that the one from the car didn’t work in the bench and I tried in boot mode, where initially it didn’t read it, it had to be read the password, I read in the obd mode the password, obd cable connected to the bench, save password on the pc, then I read the ecu for backup in boot mode. I used the cloning module in foxflash where I added the file read in boot from the defective ecu and ...

 How to simulate OBD for Land rover Bosch EDC15C4 ECU using Foxflash programmer ? obd simulation worked with the Godiag GT100 breakout box. It worked with car OBD not full system. Full system doesn’t work. Full system is not about OBD. Just do standard pinout. Read with obd protocol without resistors just k line and + -. Connect both k line for safety. Added photos:

  Foxflash read and write Fiat Talento 2021 MD1CS006 ECU successfully. Ecu MD1CS006 Read on bench ok. Writing on bench ok. Cheksum correction with foxflash. Adblue off. This ECU has no tprot. So it is possible to be done on bench. No information is displayed on the dashboard. Adblue unit must be disconnected first then plug the ecu.

  Problem: Foxflash failed to read a BMW MSD80 DME in E92 335i by OBD. Voltage is 13.6V. Solution: Foxflash MSD80 OBD takes long. For example, BMW 325i e93 took 30 min. Make sure you have a battery stabiliser hooked up. Write when quicker. Foxflash doesn’t have bench for this ecu. Remove the ECU out of car, Obd breakout on the bench with pinout and read with OBD protocol. Use godiag breakout box. Do lot of this method. Or read and write it with foxflash in boot mode. Flex and KESS3 are great in these on bench mode.

  Problem: On ECU VAG Simos PCR2.1 I accidentally wrote wrong file with foxflash over bench. And now I lost communication with it. I made backup of eeprom and flash. Now I just try every method to write again flash. I tried with ktag boot mode but have acces only to eeprom. And with Fox Flash I have error REMOVE AND GIVE POWER. Does anyone know potential solution? Possible solutions 1). Try to turn on the power supply in a few seconds as he asks you to. Some users turned the power on after a few seconds as he wanted and then it started. Also using foxflash make just set voltage to 14v , they will not communicate under 13.5v. ( see picture he used 13.4v). 2). Try this and write the All file back. 3). If tried all above and still cannot recover in boot mode, the ecu is bricked and will not live, look for a new one and turn off immo. They don’t have to match you strictly by number, you can certainly preflea it with an odyssey that suits you. Lucky for you the PC...

  Problem: It’s a Ford S-Max with Delphi DCM35 ECU. MPPS, KESS and Foxflash all read ID. But they all have problem reading flash. Kess showing wrong security code. Foxflash showing error SilentKey. The car has before made stage1 by someone else its possible he protected it from reading now or its obd impossible this ECU? I’ve read several 3.5 DCM readings in various Ford MPPS and KESS Fox models and never had a problem. What causes the silent key error? Possible reason and solution: 1). Ecu has been locked by a previous tuner. Load an original file and start from there. 2). Doing PCM update with Forscan beta or IDS. After that it will be ok. 3). I had the same problem. Write it with Autotuner , but failed, so i recovered it with MPPS, but with an other tool the security code changes automatically on OBD and Bench. So must go for BDM. It is blocked because it is writen with an other tool via OBD, you need the same tool which Stage1 was done or BDM it. 4). Try to use...

 POWERSUPPLY INFO! Since this is asked quite a lot frequently when it comes with foxflash programmer so the post here is about this power supply issue. Why? Instability or undervoltage can cause programming interruptions, corrupted reads/writes, or worse — bricking the ecu (so dont underestimate this, you dont want extrabricked ecus because of your not providing good voltage and amps ). remember that undervoltage is the main reason why you will fail on some ecus, not the tool itself. undervoltage can be fatal in some cases and that ecu is not anymore recoverable. ALSO keep in mind that overpowering ecu is just as bad as undervoltage. you will end up killing the ecu , so play in area that is considered safe 12v-14.5v say tops. WHAT YOU ACTUALLY NEED FOR BENCH ECU WORK? So when doing bench programming of ECUs like MD1, the ECU needs a stable automotive-like 12 V DC supply. It usually won’t get enough or stable power from a simple USB (no way) adapter — you want ...

  Problem: Peugeot 508 1.5 Blue hdi 96 kw with MD1CS003 ECU. Performing adblue in progress need info: Allready have benched read full backup using Foxflash programmer . File alllready modifed by tuner. Before i write I need to know do i need to reset adblue? I am not able to do it because of DTC U010E Emissions Control Can Network (Urea Pump Gauge Module) Can I upload write allready modfied file in this case and do i need to disconnect the module later. Does somone have experience with this to help? PS IS IT VOLTAGE GOOD!? 13.6 V Solution: on MD1 ECUs ALLWAYS need to disconnect module. On md1cs003 we always disconnect urea pump and module or If is a new type of fusebox i disconnect 30a fuse, diode and relay. Resets better do before write mod but not always i do, but sometimes i do reset after if still urea light on dash flashing.

  Problem: VW Crafter 2021 dcm6.2v no go with foxflash . Virtual read obd2 not in database. Solution: On some models virtual file was not in database and solution on this is to upgrade or downgrade software version. Done it by ODIS Engineering software. Or read it in boot mode with other programmers.

  Foxflash report today: Clone PEUGEOT PARTNER SID807EVO ECU successfully. SID807EVO Read/Write BOOT MODE Cloning ok Checksum correction by foxflash. NOTE: No need to read password for PSA SID807EVO, only read and write. If it is Ford SID807EVO, we need to read password first. Some users also reported that the PADFlash programmer will clone this ECU on bench mode.
