Thanks for the thorough followup. Pretty much demystifies the issue. I'm pretty impressed that your dealer took down all the stuff and insulated it.

We'll see what happens in the summer ...

Together the dealer and I measured 84- degrees c... Which is really hot.

Dealer took apart the entire trim, burnt himself on the uninsulated pipe, and spoke with BMW engineers. The engineers sent a peak and stich reflective insulation to be applied to the inside face of the interior trim in an effort to reflect the heat back into the heat box area. At the time we measured 41-c which was a big improvement.

More to come in the summer when the heat rises... So far it is tolerable
