DIAGBOX issues: No internet connection

[Roba08]

Hello
I was wondering if someone could help me here, as I'm stuck on the roads as how it looks now.
I'm a technician as a profession, i work with many computer systems, updates, scripts, electronics, always wanting to be able to access my own stuff, not being told by the manufacturer what I am able to do with my own device I fully own.
I've been looking around on this forum alot but just couldnt find the solution so far

I am stuck after many attempts to write the engine ECU type VD46
found under: Expert > Engine management computer > Repair > Configuration > Configuration with display of parameters
when attempting to configure or clear faults it tries to connect to the internet and gives the error: "No internet connection"
The other modules it seems to be able to access except the above.

car: Peugeot 308sw 2014
Hardware: full chip verison chinese clone price was around 120 or so, recently purchased with firmware 4.4.0
software: the Vmware provided by the starter of the topic.
Diagbox currently installed: v9.129
Adapters enabled but all internet connections on LAN adapter are disabled.

I have also tried Diagbox v7.57 with no luck, this version does not seem to recognize the engine ECU (VD46) very well

Is this a common error or is my engine ECU permanently locked without internet connection?

Is there a workaround to make this work or am I missing something here?

Clearing the engine ECU is the main reason I embarked on this adventure and purchased the hardware, as I have a persistent "service" light.

Thanks alot for any input on this, much appreciated

You are using Diagbox Version 9.**. All critical ECU configuration functions are secured and locked down requiring access via purchased tokens from PSA. The ECU is generally configured online via PSA servers - to avoid problems.

You may find a version of Diagbox which will work for your situation, as V9 is newer than your vehicle. I am surprised that it is insisting on connection to the PSA servers just to read and delete fault codes.

I have exactly the same issue.
I want to change my diesel injectors in the summer, so thought I'd do a trial run to see if I could change the codes easy enough.
However, I'm hitting the same issue of no internet connection.

All patched DIAGBOX software installations are ‘offline’ versions. Therefore, changes (updates) that change control units can and must never be carried out, but only read, delete and component tests. Parameter measurements, adjustments after component changes, etc.

The ‘Expert’ area can be used offline - but is actually primarily intended for online diagnostics - if something is then selected that is only possible online, ‘this also happens’.
Such areas should not be used because there is a risk of damaging the ECU.
An official workshop with a paid online connection also always receives data on possible changes and must, among other things, reinforce the vehicle's power supply with up to 180 A during the online time and the laptop must remain stable via power.

ECU updates always require a paid current PSA software, connection with the service hotline and with the conditions specified by PSA.

No Diagbox version can be used to modify control units, e.g. to ‘programme out’ something or change performance parameters etc. - This requires special device technology/software, which is available from specialised companies.
Even with the chargeable diagnostic software, updates offered by the PSA hotline require appropriate precautions - otherwise the ECU becomes useless.

Ahh gotcha.
So basically, you can't write anything into the ECU, so i'm scuppered for updating the replacement diesel injector codes.
That is a bit odd as I have watched a video of some dude explaining how to do it and whereabouts in the menus it is.
On his version, he could just ignore the bit about saying you are offline and carried on.
Maybe that was an earlier version than mine ??

You should be able to do coding of injectors, but you need an older version of diagbox which has been "hacked" for offline installation, or you need to create a servicebox account and buy a token. For an individual it can be tricky to create an account, but I did manage it last year to update an ECU software.

[GiveMeABreak]

Yes, 'maintenance' operations like injector coding should not need online access.

[cit-rotti]

Coding injectors, coding keys, resetting the gearbox, etc. does not change the software in an ECU - which is why this is possible offline.

Until around 2015, such changes were always possible offline. No code was required for the Diagbox - for older vehicles (LEXIA 3xx//Peugeot PLANET) the code 03114.

After 2015, PSA has increasingly changed many conditions in the ECU's and some changes (not all) now require an individual code, which can only be obtained via the paid service hotline in Expert mode - changes are still made ‘offline’ with the assigned code.

This has nothing to do with changing/updating the software - this was and is only possible ‘online’.

The diagnose-software version is also irrelevant. Offline changes for vehicles up to 2015 do not require a code even with the 9.xxx software - neither with the original online software nor with the patched offline software and, of course, the old code 03114 is required for older vehicles.

However, it is often advantageous to use Diagbox software 7.57 or at most 7.62 for vehicles up to 2015, as this corresponds approximately to the original software and many 9.xxx variants have falsifications and are not always complete.

What is lost from offline to online only between 7.57 (or 7.58 in my case) and 7.62. And if it's nothing why is the earlier version even recommended?

Thank you for your reply.
Thinking about updates I can somehow imagine they want to monetize their work somehow in this way, but to the very least I'm trying to reset the ECU fault codes on order to see
which one persist from the currently list shown-this in order to see which sensor is faulty, since the car is missing some performance. but is cannot even do that.

Also I want to just set some basic settings in the engine ECU, no tuning or updates. only customer customization.

Hasn't this been backwards-engineered yet i.e.: simulating a connection of this kind?

I created two VM's, one I have updated until V07.57: looking at the diagbox update changelog, this version was released the earliest 2014, the year my car was produced, I assume this would be the minimum version I can choose. The second Diagbox I have installed is one of the newest one, 9.129

- I also tried without any updating, the earliest V07.01 - as can be expected it doesn't show my model yet. (pre '14 308 release only)
I have read they've started the online thing at 2015, so I think it should be possible to configure my '14 car offline?
However, when I use this tool and scan the engine VD46 ECU, it doesn't seem to show the correct wording for all the errors and menu options within the ECU.
It looks like it does not communicate well.

When I try to reset the faults in the VD46 ECU, it does an attempt, shows "errors deleted" but nothing actually gets deleted, the faults are still there after a rescan.

I tried to go 2 versions higher, until v07.62 as described in the scary01 manual: same error: "no internet connection"

It must be possible, by a smart coder to mimic the internet connection somehow. Resetting and changing user settings doesn't require any new data..

Cheers for replies all.
Sorry to hijack your post a little Roba, but we have very similar issues. Any light shed is good.

From about version 7.62 onwards they started to remove off-line telecoding features, but this was not for all vehicles and not all at the same time. It was a gradual process. So it really depended on which model vehicle you have as to which features were slowly removed until eventually most decoding features were removed completely.

My X7 worked fine with 7.62 for everything I needed including ECU configuration but on some other models it was removed so just depends which vehicle you have. I don’t have a list because for the number of vehicles and the number of ECUS, it would be impossible to list them.

Permanent errors cannot be deleted or can only be deleted after the error has been rectified.
VM installations can lead to problems or the VCI used is a Chinese cracker.
A native installation is and remains better for diagnostics.
For a 2014 vehicle, Diagbox 7.57/7.62 must be installed directly (natively) on either Windows XP prof. 32 bit Sp3 or WIN 7 Pro 32 bit - the LAN connection (not WLAN) must work and the LAN driver must be installed. A real Internet connection must not be used during installation or diagnostics. No virus scanner - not even Defender, of course.

In principle, Diagbox 7.57 could also be installed natively on WIN 7 64 bit or WIN 10 64 bit - always Pro versions. Then only the part for the older vehicles up to about 2007 = LEXIA3 and PLANET will not work, because these require 16 bit.
And eprom versions are required for software changes to control units.
