Thanks, that's very interesting info. Let me run this by my mechanic next time!
I am too still frustrated that this problem can't be solved...

This is a long shot, but you'll find other occurrences documented in the archives: The serpentine belt is treated with antistatic material. As it wears it can generate enough static electricity to interfere with some of the vehicle's sensors. Think of a Van De Graaff generator making your hair stand up at the science museum. My search of the archives indicated this is more common with an aftermarket belt than a VW one.
I spent over a year chasing CEL issues, mostly random misfire indications. Then I stumbled on the belt/static issue mentioned in the archives. Changed the belt - no problems for 4 years.
The belt was visibly bad, though - lots of loose threads. Your fault codes seem like there's a bad connector or ground somewhere. Or perhaps they induced the faults while working on the harness. Maybe clear them and drive for awhile and see if they come back. Does the van drive ok, without hesitation?
