So I’ve done 300 miles in my S 320 with 179K on it — almost all of them without incident.

having an intermittent issue with what I suspect is a sticky brake light switch. The symptoms are: ESP / Brake assist warning+ brake lights stuck on. This only happens now and again, and the fault clears when I turn the car off then on again. Am I right in thinking sticky brake light switch? There are no other electrical issues which would seem to rule out a faulty SAM. Any thoughts?

In the absence of a Diagnostic Check on SDS to confirm I'd say that a new (good quality) Brake Light Switch would be a cheap enough punt ;)
