I regret I cannot read the photo you attached, it is too small.


Please list details of your hard ware platform and setup, Operating system (which Windows XP or 7 and 32bit or 64bit) and what did you configure when installing DiagBox.


Please list everything... I cannot see Lexia in the attached photo!!!!!


Did you also open it to see what you have received is actually the Full Chip?

ok sorry about that...ive attached the screen shot

My laptop was windows 7 but couldnt get the lexia to work so installed windows xp 32 bit (service pack 2) as this is all ive got.

The lexia software was installed first then the diagbox which i upgraded as you said in stages to 7.62

The message pops up after adding the code on the drivers door.

I got the lexia system that you said would be best (Full chip) it said.(photos attached) I havent opened it.

Thanks....it seems to find the vin number ok so i think its a problem with windows.

First: I did not get enough information on your hardware, is it a laptop, what make and model, what size is the RAM and Hard Disk, How did you setup the BIOS, is it AHCI or legacy??? and did you format the disk or create a partition...


Also, I did not get much about your Windows XP installation other than 32bit... Did you install .NET 3.5, did you install Java, what other preparation did you perform?


WRT Application, we are not there yet..


I see that you got the A.1281 Z, I was hoping to see clear pictures of both sides of the two boards inside...


The message you got indicates a problem with your Windows installation...


However, I will start  from the end.... Your installation of Windows XP is suspect (I mean corrupt).. I would reinstall from a new source. Please read you Private Mail.


Try find:

1- This CD: "en_windows_xp_professional_sp3_x86_cd_x14-80428.iso"

2- This tool: https://rufus.akeo.ie/downloads/rufus.exe


Make sure your BIOS is setup correctly. Insert a USB sick 1GB or larger or a CD. Run Rufus.exe, click on "Select an image" and point it to the WIN XP downloaded ISO and burn it on USB stick or a CD, install from it...


Or, you could attempt to repair it by reading on..



This issue may occur if one or more of the following files are missing or damaged:







Method 1

1.Insert the CD into the CD drive or DVD drive.

2.Click Start, and then click Run.

3.In the Open box, type cmd, and then click OK.

4.At the command prompt, type the following commands, pressing ENTER after each command:


expand CD-ROM Drive Letter:\i386\config.nt_ c:\windows\system32\config.nt

expand CD-ROM Drive Letter:\i386\autoexec.nt_ c:\windows\system32\autoexec.nt

expand CD-ROM Drive Letter:\i386\command.co_ c:\windows\system32\command.com



5.Start or install the program. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to the next step.

6.Note: The Command.com file is not edited or created in the following process. Because of this, you may have to expand it from your Windows XP CD-ROM.


Start Notepad.

7.In Notepad, type the following entries: dos=high, umb




8.On the File menu, click Save As.

9.In the File Name box, type Config.nt, and then click Save. Close the Config.nt file.

10.On the File menu, click New.

11.In the new blank document, type the following entries: @echo off

lh %SYSTEMROOT%\system32\mscdexnt.exe

lh %SYSTEMROOT%\system32\redir

lh %SYSTEMROOT%\system32\dosx

SET BLASTER=A220 I5 D1 P330 T3


12.On the File menu, click Save As.

13.In the File Name box, type Autoexec.nt, and then click Save. Close the Autoexec.nt file.

14.Start Windows Explorer. Locate the Config.nt file, right-click the Config.nt file, and then click Copy.

15.Right-click the %SYSTEMROOT%\System32 folder, and then click Paste.

16.Locate the Autoexec.nt file, right-click the Autoexec.nt file, and then click Copy.

17.Right-click the %SYSTEMROOT%\System32 folder, and then click Paste.

18.Locate the Command.com file, right-click the expanded Command.com file, and then click Copy.

19.Right-click the %SYSTEMROOT%\System32 folder, and then click Paste. Restart your computer.

If the issue continues to occur, copy the Autoexec.nt and Config.nt files from the Repair folder in Windows to the System folder. To do so, follow these steps: 1.Click Start, click Run, type c:\windows\repair, and then click OK.

2.Right-click Autoexec.nt, and then click Copy.

3.Click Start, click Run, type c:\windows\system32, and then click OK.

4.Right-click anywhere in that folder, and then click Paste.

5.Right-click the Autoexec.nt file that you just copied, and then click Properties.

6.Click to select Read-Only, and then click OK.

7.Repeat steps 1 through 6 to copy the Config.nt file.

Note You must enable Read-Only permissions or the files will be removed after you restart Windows.


Method 2

1. Click Start, click Run, type C:\windows\repair, and then click OK.

2. Right-click the Autoexec.nt file, and then click Copy.

3. Click Start, click Run, type %windir%\system32, and then click OK.

4. In the System32 folder, press Ctrl + V to paste the Autoexec.nt file in this folder.

To make things easy:


1- In the Notebook BIOS set the Hard Disk Controller to Legacy.

2- Download a proper Windows XP SP3 ISO and burn it to a USB stick or a CD..

3- Install Windows XP (do not download Windows updates, not needed).


Follow the DiagBox installation manual:


For DiagBox 7.xx, you can use your name or any other name, but if you have had the previous failures on the same Windows XP installation, I would strongly advise you to use "DBCleaner v101a" making sure you run it as Administrator.


If your notebook currently runs Windows XP 32 bit, you can install Evolution XS (Lexia) applications directly on it. However, many of the currently available notebooks are unlikely to come with Windows XP; in which case the best way would be to shrink your last partition by about 40 GB and create a new partition to install windows XP 32 bit on it, then the Lexia application. Nevertheless, you can run Windows XP (and many other operating systems) within a Virtual Machine installed on your current notebook’s OS; luckily, they are mostly free and readily available. I have tried both methodologies and both work well, I have preference to the Virtual Machine because I still have access to my other operating system (in fact I am writing this whilst performing another test). One can also change the amount of memory (RAM) or computation power (CPU) as need be, you can clone it, and if you do not like it, you can delete it.


Let’s Start:


Ensure that all files and folders names do NOT include spaces or funny characters, example: “Folder_1or_file_5†and not “Folder 1 or file 5â€. If possible, convert all your media to ISO format ensuring the media is laid at the root directory and NOT inside another folder, Example: if you mount the DVD ISO it should be “G:\installation_material†and NOT “G:\Lexia 3\Diagbox\installation material†(where G is the arbitrary DVD drive letter).

1- Install VirtualBox, the Extensions and Guest Additions, ensuring the following:

a) The Hard Drive controller must be IDE.

B) Create a preferably fixed hard drive more than 24GB. Dynamic also works.

c) Connect the Windows ISO through the Settings -> Storage -> Optical Drive.


2- Install a clean Windows XP Pro SP3 and activate it and install the following tools:

a) All necessary drivers.

B) Setup a network adaptor

c) Install Mozilla Firefox

d) Java 7

e) Winrar or 7zip

f) Virtual Clonedrive (not needed for VirtualBox)


3- Connect the Lexia USB interface to the computer so that VirtualBox identifies it:

1. Click on VirtualBox Settings, USB, Add a new USB filter and choose the code representing Lexia interface.

2. Leave the Lexia interface connected throughout the whole installation process, if Windows asks to look for drivers then just cancel for now.

4. Disconnect the network cable.

5. Create a blank file named version.txt in C:\ i.e “C:\version.txt†(This step may not be necessary with newer DiagBox versions).

6. Mount the DiagBox 7.02 ISO and run the setup, go through the process. At some stage, "new hardware found" window will appear, do not choose to search automatically for drivers, you may cancel it or just manually select the driver that should now be available.

7. Once done, start DiagBox and when prompted for activation, choose the "manual activation" option, fill-in information as per the provided instructions, usually (Customer Code, Address, Post Code and Car Phone) you can enter any characters or numbers.

8. Start DiagBox again it will run the update for 7.02.

9. Install the update package/s – I prefer the 7.xx to 7.57. Please note after installing the update you will need to reboot then run DiagBox for the update to be fully installed. At some stage, the drivers may install (if not already installed) where you will get "New hardware found" wizard again.

10. DiagBox (the latest version installed) is now operational.

Connect the USB interface to the OBD-II port on your car, turn on the ignition, and in DiagBox choose your car, insert your RPO and work away.

thanks simple

i found 3 files missing in windows....downloaded and added them...all working now.

Just connected it and run a diagnostic....shows loads of faults ( injection doors etc)

no idea what to do with it all now though LOL

said ive got loads of faults

Just wanted to check if my partcular filter is any good or if its a sensor fault...found the problem with my reverse sensors though (although ive sorted already )

Nice bit of kite some how saved the info

Im scared of breaking my ECU or creating more problems messing with it....

Ive some how saved the data (which is even more confusing)

Can i read it outside of diagbox ?

I need to jus mess with it i think....at least it sees my car now... :D

It is nice to hear all is well, As long as you do NOT attempt to change/delete configuration you will NOT break your ECU..

I would save all errors, then I would clear all of them... then after a couple of days/weeks or so, I would check again and compare...


Permanent faults indicate faulty sensor or component.


Intermittent faults indicate, erroneous sensor, loose connection.. etc..


I am glad it worked and in your opinion, worth it..


p.s. The reason for the missing files is unknown in your case. I would still reinstall Windows and DiagBox, because if your original source is virus infected or damaged, it will only get worse after a while and it could cause erroneous data passed to the ECU.

Thanks again simple

I will try to figure out how to clear them all as you said but still not sure how to....I tried one and it said cant...something about have to clear ECU I think.

been on youtube but only things I can find on using it is how to install or update...not much on using it


PS sorry for late reply....the forum wont let me post on my mobile as I cant log in for some reason...ive emailed them but had no reply

You can clear faults only after reading them (to give you the chance to store fault list)..


You may fail to clear some faults; check fuses, connectors, ignition on, etc... or it could be DiagBox software (shaky installation) issue; (downgrade to DiagBox 7.57 or/and manually flash Firmware 4.2.4 to verify) or Lexia hardware issue.


Do not allow suspect issues waste your time, some fault reports are not decisive... It could take long time until you find the real reason for a fault and changing the wrong parts is also costly.


p.s. You have not posted photos of your boards!!

FAP Lite is free on Google Playstore.  Its apparently designed for all PSA vehicles, but only reads the engine and gearbox ecu fault codes and EOYLS tank contents - so not a substitute for a Lexia.  I've used it for a year and it works great on my C8.  You will need a bluetooth ELM 327 transmitter to plug into your diagnostic socket (available from eBay etc), then just download the App onto your Tablet or smartphone.  For some reason the full App (FAP) is only available from Amazon - for around £8.50 I think.  FAP allows you to read all the engine parameters - like airflow, turbo pressure, fuel pressure, Cat temperatures, DPF diff pressure, air con pressure, etc etc.  You can also test cooling fans, pre-heat system and the EGR valve function, and allows you to reset fault codes - not sure what gearbox function it has as mine is a manual.  I have found it brilliant for tracking down tricky faults on my C8. 

    NB I am not in anyway connected with this product - other than being grateful for its existence.  Its not a substitute for a Lexia clone, but it is a cheap and easy to use tool - and the only OBD reader I have found that works well on my C8.
