the adapter shown by "vonHabe" fr 10. jun 2022 16:21" is not an Actia original adapter for the Lexia 3.
The original adapter has a round plug connection to match the VCI, which has a round coupling. The adapter was only added later by the Chinese after the OBD 2 cable. But the older vehicles are not OBD2 at all.
Whereby there were 2 originals:
1. for older diagnostic systems before the LEXIA 3 (e.g. LEXIA 2,PLANET, ELIT etc.) and
2. from LEXIA 3
Originals cost around 210 DM (approx. 105€) at that time.
Because there are so many faulty 30-PIN-adapters available, only a few ECUs are recognised. This is not a problem of the LEXIA 3, but because of the faulty wiring, the control unit cannot be accessed or sometimes the 30-PIN connector has only poor contact.
For these older vehicles, the diagnostic device "ELIT" or alternatively the LEXIA 2 was the better choice.
In the forum "
https://frenchcarforum.co.uk/forum/index.php" there are concrete guidelines for changing/adapting the adapters.
Since the number of vehicles affected is decreasing, the problem is of little importance.
