ColorMFA on Audi A3 8P

[autopilot]

after changing the setting to canbus+

Do not select "CAN-bus+" if your motor ECU is not adopted for this mode. Need select "CAN-bus" (w/o "+") for typical motor ECU.

won’t read any module at diagnosis

What options are enabled in Debug->Diagnostics->Protocols ?
What protocol is used when connecting with a diag.tools (VCDS) ?

Hello again! Managed to read some of the modules after setting can tp20 and diag gw. I can’t read engine or airbags for example , those use uds protocol, also can’t read cluster or immo and those use can protocol but i can read abs, Doors, steering wheel, central electrics. Any idea?

Protocol: UDS
ColorMFA does not support UDS.

Protocol: UDS
ColorMFA does not support UDS.

no plans to support it ?
I was looking forward to continue working on this and eventually also show ACC and TPMS high on it , but this will need BAP and UDS support

About BAP:
It is a protocol that defines the order in which data is transmitted. And only this. For each device, the transfer of the data itself is very different. For navigation, there is their own data, for radio/sd/cd their own, etc. In addition, there are different versions of devices with different protocol versions. Currently, ColorMFA understands parking sensors, rear view cameras, navigation and audio data with version 3 protocols. If you need to add support for another device, then you need either a description of the operation of the protocol of this particular device, or got detailed logs and figure it out yourself.

About UDS:
I'm not sure that full support for this protocol will appear in the near future. The basic functionality (connection, getting data about the device number, encodings, parameters, reading and erasing error codes, reading measurements, etc.) has been implemented in ColorMFA more than two years ago.
But this is not enough. VAG companies decided to make some of the data hidden from outsiders. Therefore, for example, most of the ECUs when reading errors give out their internal error code and in order to find out what kind of code it is in reality, you need to have a correspondence table of the received code and the one that needs to be displayed to the user on the screen. For different devices, these lookup tables are different. In the same way, everything happens with the reading of measurements (there is no more group reading of data in this protocol).
Unfortunately, I do not yet have the necessary data for a full-fledged implementation of the UDS protocol.

Thank you for the detailed information.
I think I will finish the implementation of tpms and acc with a VW cluster on the A3 and maybe we can work together to integrate it in to colorMFA, I really love the A3 cluster and do not want to move the VW in case I make it work with colormfa.
Let's how this will go and when we can order new colormfa , I still have 1 not installed and if you have the time to work on this next year it would be awsome, I offer to help everywhere I can.

Cheers,
