Reflashing colormfa for audi 8E to Golf 4.

[Ballie]

Hello, i currently having a colormfa for audi a4 8E laying around which i want to use in a golf mk4.
Problem is that the 8E didnt have the inputs for mfa handle.
Due this setup i cant open bootloader to reflash to golf 4.
Me was told to ground key 1 and then add the power to the 12v pin but nothing happens.
Anyone has another option?

Greetings.

For 8E bootloader need ground key2 before apply power.

Hello Friends,

I dont want to create new topic so I will ask here.. autopilot, so I can move my ColorMFA from Golf cluster to Audi cluster and only reflashing board using both files for Audi firmware, correct?

Thanks in advance.

If you have full soldered ColorMFA main board:
Yes. But you also need to do a full reset through the hidden menu. Debug->Reset All->Yes.

If you have a Golf-only ColorMFA main board, without some components: you also need to solder some CAN bus chips to ColorMFA main board for full A48E support.

Thank You for answer.

Ok, lets forget about MFDB v3.2 from my old Golf cluster (sold).
I have also brand new ColorMFA from 16th batch MFDB v3.4 - this one was also bought for Golf cluster.
I suppose that this one unfortunately need some components... right?
