The only thing I can find is a faulty parking aid module. Have it scanned for codes.

Yes, it is possible. Did whoever scanned for codes scan for soft codes as well as hard codes? Most shops or facilities that scan for codes won't poll for soft codes unless you ask and give them a good reason. Such as your issue.

See image attached for parking aid module location in trunk.
