This package provides a small Windows tool for working with BCM / CCM dumps from VW Passat B6, Passat B7 and Passat CC based on the PQ46/PQ47 platform.
The application is designed to analyse 95320 EEPROM files from the comfort control module, calculate CS related data and help technicians during BCM replacement or cloning jobs.

Thanks for the upload!

This looks like a handy utility for the PQ46 platform. Just to clarify for anyone else looking at this, this is specifically for the CCM (Comfort Control Module) usually found behind the glovebox (Part numbers starting with 3C0 or 3AA), correct? Even though the title says BCM, the Passat B6/CC usually stores Immo data in the CCM 95320 EEPROM.

A couple of questions:

Does the tool automatically recalculate the checksums when we modify the Immo data (CS, PIN, MAC) for cloning purposes?
Does it support decrypting the 7th byte of CS if we only have the first 6 from the ECU, or is it just a viewer/editor for existing known data?

I have a dump from a 3AA 959 799 unit read with VVDI Prog. I will test this out and see if it parses the key IDs correctly.
