P0884 TCM Power Input Signal Intermittent

I searched and searched to resolve this problem, and nothing..

I repaired all the spliced lines passenger side..

New TCM installed
New Harness Installed
Identical Part #
I checked the BAT+ on tcm OK
I checked the Ignition + on tcm OK
I Checked Ground on TCM OOK

RED = + Power Batt
Black = + Ignition
Brown = Ground Chassi

Can anyone help me on original clean readable electrical schematics
for Audi a6 2004 Quattro Turbo

Also what would be the trouble block diagram for this Error code..

I Triple checked every line in the passenger side.. Replaced all damaged spliced lines..

I need an expert help here.. Possible solution..
