I'll try to check it out.

[boubou]

Is it as if the colormfa doesn't come out of sleep mode? How does he wake up?

[autopilot]

There are 2 ways to wake up. Switch On the ignition and any activity on the CAN bus. Both are implemented in hardware.

[boubou]

I can try to go back to old version if need to see if it still makes the same problem?!

[boubou]

Movie for explain

phpBB [video]

It does not work properly without ignition.
Are you sure that you do not have any devices that can block the CAN bus data without Ignition ?
Additional alarm, immo off, e.t.c. Check all fuses...
It looks as if the dashboard is not receiving CAN-bus data when the ignition is off.

[boubou]

I have the OEM alarm, the patch for the mirors folding to the remote control and that's it.

Immo ON and no element that blocks the CAN normally.

After Ignition ON ColorMFA perfectly

You can try other firmware versions. But I have no information that this problem exists on other VW cars.
What errors are there in block 46 (Comfort system) and 17 (Dashboard)?

[boubou]

No error ‍♂️ 17/46/19

I will try B34 for testing ?!

Are you sure everything is installed correctly? Are the dashboard connectors installed correctly?
All pins are well soldered, the wiring is neat, no snot after soldering, no short circuit, etc.
In the first video, you have small screens blinking. This is incorrect and may indicate installation problems.
Take a photo of the Hardware->HW Info on ColorMFA hidden menu.

Hello, I come back with a more serious problem

I wanted to put an old firmware and the USB connection was interrupted during the transfer!
Now the colormfa does not turn on and the cluster no communicates via CAN with airbag, engine, etc. the K line yes.

Is there a solution to restart the firmware?

[autopilot]

Remove cluster fuse. Press and hold "Reset" button. Put fuse back. ColorMFA must run in bootloader mode. Release "Reset" button. Turn On ignition, connect USB and update firmware.

today i disassemble the cluster and clean all solder points with isopropyl alcohol and now everything works.

You are a GOD

I put the b35 to test my problem

Thanks autopilot

[boubou]

Hi,
Tested with b35, same problem.

The problem can come from the cluster which is a lowline?

[autopilot]

I have not encountered such a problem. It doesn't matter which dashboard is installed.

[boubou]

I must be the only one to monitor the "problems"

CCM problem ?

Test b34 ?

[autopilot]

At the moment, only you have reported such a problem.
The guys I asked (on Golf) say that everything works as expected.

Thanks autopilot, i will try full FIS OEM for testing.

Is possible bad settings on debug ?
