Someone has just uploaded a video of a MK4 cluster performing a needle sweep on startup. The comments seem to reveal that it's a Passat board with over 200 bits changed in the EEPROM.
Now, does anyone know what's been changed, or have a copy of said EEPROM?

You can do this with VCDS to test the needle sweep. Maybe that could clue us in.

Graeme, I have tracked the guy down his name is Svenni from R32club.de but I cannot register to ask him how complicated the module is to build.
His username is Bisheep on r32club.de.
There was also some talk about a square wave generator tapped into the signal feed to the cluster, triggered with ign on

I've got it to sweep round but it stays at the max position. I'm going to try a Passat flash.
People are saying they're "injecting custom code" but that's not a thing in an EEPROM that size.
ALSO: Why are people being so secretive? It's a MK4 Golf ffs.

Very interesting that these clusters allow a "code patch" residing in eeprom area.
Does anyone know if newer types of clusters like VDO NEC (PQ) support such feature also?

I implemented this the other day and it works.
I want to know HOW it works though, but that doesn't seem to be an option.
I read through the datasheet but nothing really stuck out.

adam- do you have any datasheet for micronas used in the clusters?

Isn't it just simply some assembler code block?

I don't think so.
The EEPROM just contains settings AFAIK.
