Electrical problem
2007 Audi A4 6 cyl Two Wheel Drive Automatic 50000 miles

I have for repair this A4 2007. Instrument cluster is intermitent faulty.
What I need is PINOUT for this instrument cluster to be powered out of the vehicle.

To be more specific...Wich pin is + and wich is -

If I need to replace the instrument for a used one, I need to read the existing mileage to "unlock" the programming "writing" process. For your knowledge... The data in this cluster is encrypted, so the only way to modify miles in the new cluster is reading his actual mileage and "then" put the new one..

INFO:

BOSCH RB8
8E0920 951G

I found the answer by myself...... Here is what it's work for me.

GREEN CONNECTOR

PIN # 1 2 3 POSITIVE (+)

PIN # 18 19 NEGATIVE (-)

Mileage reading will show up for just 2 seconds and then SAFE is displayed.

Hope this help to others!!
