Got Proscan Automotive dongle advertised as Mini ELM327 OBD2 V2.1, however vag dpf free i snot supported as well as protocol goes only to v2, not v2.1 as advertised. Dongle is being returned but I would like to know if version needs to be > 2 to support vag dpf app?
thanks

The ELM327 identifier report doesn't tell you if the adapter works with every supported command, it only reports which commands are recognized by the adapter, but during its functioning it couldn't manage well some of them, as usually happens with low cost adapters.

Dongle from ebay description says it supports following:

ISO 15765-4 CAN (11 bit ID, 500 kbaud)

ISO 15765-4 CAN (29 bit ID, 500 kbaud)

ISO 15765-4 CAN (11 bit ID, 250 kbaud)

ISO 15765-4 CAN (29 bit ID, 250 kbaud)

So I guess this is a good case for return because it does not match description.

VAG DPF requires at least an ELM327 version 1.3.

If your dongle declares the v2.1 compatibility, you can return it because the support is only partial, watching the ELM327 identifier report.
Support for the 4 versions of ISO 15765 protocol is present since version 1.0 of the ELM firmware, but in any case also if a dongle would supports every AT command, if it works bad you should return it.
