  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.  

  Problem: Cannot get Foxflash working today. Error: There is a problem reaching the update server. Solution: so here’s the quickfix from one of our users FOR THE UPDATE SERVER ERROR! Download link and unzip to foxflash folder, then make a shortcut on desktop of the foxflash software. [https://files.fm/u/cn4dk6m6jz] Be sure to install also drivers, found inside folder.

  Problem: Tried to read and write Simos 18.1 ECU with Foxflash but extract password not working. Solution: Voltage is not good. User feedback: Solved! Had a problem with the resistances, the voltage is true, the power supply died and did it with the standard. READ OK. WRITE OK. CHEKSUM OK FOXFLASH. STAGE 1 + POPS VW GTI 7 2.0TSI 230CV

 Read and write Skoda Fabia 1.2 12V Siemens Simos 3PG ECU with Foxflash successfully. Lambda OFF. BOOT Read 2min. BOOT Write 4min. Checksum by Lsuite. FoxFlash does not correct the checksum for this type driver. Only self do with other software like Lsuite.

  Problem: No red light on Foxflash programmer bench box and switch, has happened to anyone? Solution: Light comes only when tool start reading, when it says keep ecu power on make sure switch is at 1, then press ok that’s when the light will come Power will only come on in bench mode after the program prompts you to press the power button. The power button will then light up for one second and turn off again. See on bench box, when the red light turn on, you got power on switch, and light is turned on. It automatically goes red during read or write when the software requests it to Only power needed on read/write.

  Problem: How do I read and write down a driver in a vw dcm6.2v with foxflash in boot mode, because after installing stage 1 (via OBD) the car does not start and I can’t bet anything? Solution: That situation usually comes from checksum handling or wrong patch area — DCM6.2V is picky. If you can still read and connect to ecu, write original file, test if it starts. If yes, then manually checksum the file and write it back. If it still causes problems solution is not good (bad file). Foxflash don’t have bench or boot protocol for this ECU. You can also take boot read and restore ecu.

 It’s a SSANGYONG ACTYON 2009, 2.0, 104kW. ECU type: Delphi DCM3.2AP Tool used: Foxflash Mode: BDM mode. BDM MPC 55x/56x full backup with foxflash. Checksum correction by foxflash, IMMO OFF ok. ST95320 eeprom write back with TL866II programmer for set write protect.  

 Renault SID306 ECU cloning is done with Foxflash programmer. Continental Sid306 Infineon TriCore SAK-TC1766 boot mode clone ecu. Need attention for pinout because very small in ecu pin. Cloning cannot be done on bench. Read in boot ok. Write in boot ok. Checksum by foxflash. Better keep power supply 12V+.

 Foxflash new user feedback: This is a Volvo ECU. Siemens sid803A. Done via foxflash. Read ok. Write ok. Checksum by foxflash . Note: It was under full system. Not in bench section. All done under 5 min. It worked without any problems.

  Problem: Foxflash failed to read VW DQ250 gearbox from Golf6 GTi on bench. Error no Flash, no Eeprom, no Backup? Solution: Your voltage is too low. You’re running way under 12v and doing DSG gearbox. Add 13volts and some amps. Then try again. On these 02E Foxflash works better than PCMflash. You need OBD to DSG socket cable and manual power switching. Or use godiag ggt107 gearbox adapter.
