DIAGBOX issues: No internet connection

[Roba08]

"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

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."



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.

Did you find a difference in using a native install vs VM?

[Roba08]

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?

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.

makes sense. would be interesting to know what an extenally "locked" engine ecu looks for, really. Might work the same as a radio remote locking key, like a token given from PSA must be matching a database it has installed.

might need to try cit-rotti's suggestion.

Online telecoding validates a purchased token for a 'session' - for example either for the VIN of one vehicle for 2 weeks or 2 vehicle VINs for 1 week, so it is validated via the 2 way communication with PSA servers. These are uniquely generated for each session then expire.

The things that seems strange to me are that generic diagnostic boxes can at least read and clear codes without access to the PSA servers, and this is a 10 year old car, but we have never heard of this diagbox limitation (on reading codes) before.

[GiveMeABreak]

Diagbox fault codes can be read and cleared and basic maintenance operations (like resetting additive counter for example) without online access to PSA servers regardless of version.

It's ECU configuration that is restricted now on later versions of Diagbox V9. However, Diagbox 7.* to about 7.62 (assuming your model is 2014 -15 and with ECUs that are of this year, or earlier) will be ok for some telecoding. Exceptions are some head units like the RT6 are locked though for ECU configuration if they have issues after a firmware installation that resets the unit.

[xantia_v6]

Diagbox fault codes can be read and cleared and basic maintenance operations (like resetting additive counter for example) without online access to PSA servers regardless of version.

That is my point, but the OP said:

when attempting to configure or clear faults it tries to connect to the internet and gives the error: "No internet connection"

[GiveMeABreak]

That's likely to be the normal issue of Diagbox trying to connect to the servers all the time. It often did this on DB 7 where you had to keep saying no all the time. I found removing any automatic internet connection wifi hot spots prevented this from being able to do so, whilst ensuring the adapter itself remained enabled to prevent licence issues / deactivation if it connected.

[Roba08]

tried today with V07.57
I could change/configure data in other ECU's in the car with success like the BSI2010 ECU.

It did not recognize the V46, with unusual naming:

some of those modules it does an attempt to clear the faults, most of them report the no internet connection.
higher DB versions don't have this.

[xantia_v6]

The ECU not recognised is a diagbox problem, I have it on my 308 with EP6CDT engine. I find that If I manually select the ECU type then all operations are available (including ECU software updates when connected to a PSA server).

As ‘Marc’ writes, it is completely normal for a connection to the Internet to be offered.
Sometimes this is only offered once and sometimes it is repeated several times - especially when EXpert mode is selected.
This must always be denied in the offline diagnosis - otherwise it will only ever do laps of honour.
With the original online diagnosis from a dealer, the fitter has the choice of using this.
If it is not possible to work with standard ECUs, this is usually due to a bad VCI or rarely to the OBD socket.
With the older software versions (LEXIA/PLANET), it was sometimes helpful not to select the global test, but to start the diagnosis via the individual test. Otherwise, the only thing that helps is to try a different VCI.
