They confirm the module isn't responding at all, but that doesn't really tell us why. It would be good to see a log of it working, to compare. If you are able to get the module to talk with VCDS, then make debug logs with level 1024 and 1048 in VCDS.
Is there any way to get the scan to skip 22, meanwhile? I’d really like a complete scan, as a bunch of work is being done on the car this week.
Thanks,
A.
