Audi RNS-E PU Pin Code Problem

[a4udi]

Hi, I have a RNS-E PU (8P0 035 193D) LED Screen Model.

Unfortunately, no pin code.

I'm tryin to find the pin code

I have to update the device with a CD titled "Audi RNS-E 2010 Unlock.iso"

Previously serial number appears on the screen.

Serial Number: AUZBZ7K7000389

After Update now have this screen: 8GSRP

Please help me. Regards.
