Some people have complained about not being able to "Telecode" in newer versions of DiagBox (v7.63+), but they said that they were able to "Telecode" using (v7.62) and older.. Upon comparisons and helped by information released by others on various forums, the reasons seem to be in the Vehicle files (From A7 to Z9) in folders:
"C:\AWRoot\dtrd\tree\Vehicle\ " and "C:\AWRoot\dtrd\tree\Vehicle\SUREQ\ "

These files (that need to be edited for all PSA cars) are too many (hundreds according to some and thousands according to others), but they are TEXT editable, and if you look into them you will find few lines indicating their "Telecoding" function and saying something like:
------------------------------
<SubTree posc=3 posl=8 destc=3 destl=10 ident=19 FileName="script_telexx_ManualTelecodingConnected.s" IsCritical="NO">
<FilePath path="TeleXX_TPM">
</FilePath>
</SubTree>
------------------------------
These (4) lines do NOT exist in DiagBox releases where you CAN perform Telecoding.. So, I am not sure if the best option is to remove/comment them or to change IsCritical="NO" to IsCritical="YES"..
Also, they are preceded or followed by a script starting like this:
<Act posc=a posl=b destc=x destl=y ident=z>
<MathAndLogic>
<Assignment>
<Source>
.......
.......
</Source>
</Assignment>
</MathAndLogic>
</Act>

If the 4 lines are removed from the script file, then the values of "destc=x" and "destl=y" in the "<Act .." statement are replaced by the values in the "<SubTree .." of the removed statement. I don't know what does the value of "destc=.." represent, but "destl=.." seems to represent the number of characters between quotations in "FilePath path=" statement.

I have also noticed that few files have been removed from newer DiagBox releases and if you copy them from v7.62 and older to the same location in the newer DiagBox versions, they work. Examples:
"a08can_feux_brouillard_surequipement_install_desinstall.s" in "C:\AWRoot\dtrd\tree\Vehicle\SUREQ\A08CAN\BSI"
Or,
"tlcd_fullprocedure_PR00.s" and "tlcd_fullprocedure_PR01.s" in "C:\AWRoot\dtrd\tree\Vehicle\SUREQ\A9\BSI"

I understand that some people are working on this issue, but because the effort is so huge, I thought users may also take ownership and attempt to enable and test "Telecoding" on their own cars themselves, which is quite easy. This will help speed up creating a database of modified files sooner (if they report their modifications and share their experiences). But remember, before editing any file, it is wise to make a backup copy..

The problem is that the cars are not listed by name, but by code!!! So I have attached a "PSA_CAR_Codes" list. I cannot vouch for the accuracy or completeness of the list and members are invited to contribute, correct and/or improve it. For example:
T84 is Peugeot 3008 and X7 is Citroen C5 etc...

Hint
The name of the sub_folder indicates the "Telecoding" area in the car (like BSI) and the name of the function in the file indicates what does it do.

As always, I have posted this thread in line with my strong belief in the principle of "Sharing Knowledge and Empowering Users".. After all, this is a "Forum" not a download site!!
