After a few suggestions to look at the head gasket possibility again, I did.
The oil is very clean but the coolant reservoir is about 3/4 low although very
clean. The head gasket was changed by the dealer at about 73K but that was
over 10 years ago. The car was in storage much of the time since then.
Is it possible I was chasing the wrong issue when I had the sudden the
hesitation in acceleration? There was a slight white smoke when I first
noticed the hesitation but it has gotten much worse. There is one thing to
note there was never an issue with the engine temperature, it was steady and
within normal range.
Is there a test to confirm that exhaust is mixing with the coolant and it's
either a bad head gasket or cracked head?
If it is the head gasket can I drive it to a repair shop for repair considering
it's not running hot or will I potentially cause more issues?
What can I expect to pay for a head gasket replacement?
Thanks,
Bob

However the KE-jet system was used in other cars, so a good Bosch
service centre may be the go.
Overall the system is not that complicated but diagnoses is easier with
the right tools and knowledge.
There are flow charts out there for the steps needed to diagnose the
KE-jet but they assume the availability of the correct tools.
By the sounds of it there is something major wrong, even if the system
goes into fail safe/limp home mode, it should still not bellow out
smoke, especially white smoke. As the system falls back to K-jet mode
and will be running a little rich.
White smoke is coolant being burned in the combustion chamber.

A head gasket R&R on a M103 is not difficult and should not be that
expensive.
The special tool required is a 12 point hex socket, which is not
expensive and you'll need a head gasket kit, which is also not expensive.
I oil has not got into the coolant, you won't need to flush the system
but grain the oil and remove the filter before doing the gasket, as the
filter gets in the way.
I prefer to drop off the manifolds from the head, as that makes pulling
the head off easier, some prefer to leave the manifolds on, works either
way.
