Folks,
I must say the chaos continues. I recently had the steering wheel
changed on my VW Tiguan, apparently a common occurrence.
I kept bleeping and telling me that "travel assist" wasn't available and
you couldn't disable the very loud beep.
There must be some design issue with the capacitive "buttons" or some
sort of wiring short....
... however chatting to the parts guy about some other bits he said it
must have cost VW a lot as it took them a while to trace the fault and
fix the wheels design.
.. in the meantime some cars went through multiple wheels....

That’s a good business practice anyway. You want your high price system up and running as
fast as possible, so not having to do more than cursory diagnostics is a good thing I
think deck realize that with the VAX and it’s remote the diagnostic capability as for the
board breaks, IBM used to do that for all the boards they replaced. They even had a
special board breaking tool.
My CE from IBM said that it costs IBM more to diagnose a faulty board than it does to
make a new one so that’s why they do it. Breaking the board also ensures that the
engineers won’t get caught up in a side project trying to figure out what went wrong.
That's true for problems seen occasionally. When people realize a particular
issue appears "too often" it does become an engineering matter, because then it
indicates an issue with design or manufacturing or part selection.
For example, I remember a product that had a memory backup battery issue, which turned
out to be a change in plating for the battery holder. For engineering it turned into an
exercise in learning what "electrovoltaic series" means -- not something
familiar to most digital logic EEs.
