Are these clusters that suseptable to dead batteries that itll currupt the cluster eeprom? Thats kinda messed up and cheap on audis part and really f'd up for a person that does know about tuning and eletronics(most people that drive these cars)

Verified. But this would have been easier if you'd used the same e-mail address to join the forum and buy your VCDS. ;)

As a general rule, no. But let's not lose sight of the fact that this cluster is 16-17 years old now. That's like 90-somethig in people years.

As for it "in shambles", I have a fuzzy recollection that these late-mode 4B clusters always gave the typical mileage and immo tools fits.

Those clusters may have 2 K-lines, one for diagnostics, another one to communicate with ECU. Aren't You trying to connect to second one on the bench? Just a thought, I'm too tired after 6 days and some nights working this week to get up and start another computer with wiring diagrams right now, sorry. I never had any problems connecting A6C5, A4B5, Golf4, PassatB5 etc similar clusters on bench. They all are similar, but pinout may have some differences. Post an autoscan with cluster connected to car.

Code:
blue/7	  gnd
blue/9	  gnd
blue/24	  gnd
blue/1	  +12v
blue/23	  +12v
green/28  K
This is what I have used in A6 C5 facelift clusters.

Its pin 28 green, my blue 25 is no wire connection on the connector. The w-line is also on the green but not used (i guess) on bench test

What a Jelly donut? So where is the auto-scan and did you succeed with your FOD golden shower yet?

Did you undo the induced FOD & set the ECU back to a status it can be adapted too or manually flagged for reach around?

Autoscan is always useful for others willing to help OP. For example in Your case in autoscan I could see IPC HW/SW partnumbers and versions + coding without asking You several questions and explaining what number/code exactly I want to know. And autoscan eliminates human factor faults (missreading, misstyping etc) - VCDS read all necessary data from modules and save in autoscan file automatically and correctly.
