The self study guide for the Audi Q7 [SSP_364 Audi Q7 Electrical Systems] clearly states on Page 15 that the Q7 J644 is "identical to the control unit known from the A6 '05 and A8 '03".

SSP_364 then goes on, across about 6-7 pages, to describe the history logs that the J644 writes and can be accessed from the VAS5xxx 'Directed Fault Finding' screen.

Does VCDS offer the facility to read and display/dump these logs please? [In my case, off an A8 D3 MY2005].

Thanks - Julian
