Thanks Hendrik, I will try to get the numbers and bild month.
The regeneration valve/ERG I think I can find. Is the MAS the
throttle body, or is that a different component?
How/where do you find the idle speed controller?
Would any of these components possibly still have self-destructing wiring?

OK I am having a gander at the WIS and so far the MAS and
regeneration valve (which I understand the EGR valve to be) are
looking like culprits that can cause fluctuating idle.
The regeneration valve can be blocked off to eliminate it.
Also check that the vacuum hose from the regeneration valve to the
idle speed controller is in working order.
Another but more of an outside chance is insufficient ignition
voltage but that would not be dependent on engine temp.
It does help in cases like this to have the month and year of build
as well as the VIN and engine number as the WIS has dates in which
faulty components where installed.

Runs fine until warmed up, but a little tendency to search. (fluctuating RPM)
When warm, will die at stops, probably due to searching.
Any ideas what could cause this and how to test components other
than the stealership plug and $$$Charge$$$$ method?
