Several threads in MBO (and elsewhere) have dealt with this “mysterious issue”. These MBO threads were interrupted in 2010 without (that I am aware of) the problem being identified and solved.
I own a 2005 Mercedes E220CDI with 230.000 km on it that is suffering from this very same cold stall issue for the last 6 months.
In a rather succinct way, what happens is:
Engine started after car being parked overnight. Engine starts and idles very smoothly, but the moment D or R are selected from P, the engine stalls. If left idling (in my case) for as long as 8 minutes (depending on ambient temperature) one can switch from P to D or R without the engine stalling. Car runs very smoothly shortly afterwards. Engine stalling only happens “once a day” meaning that you can park your car for several hours and then be able to start the engine and instantly drive away without the engine stalling.
Several MBO members have reported and dealt with this issue: rich.g.williams, reuben and others made some real good contributions in (see last few pages)

The bottom line was that after a lot of effort, creative thinking and many $$$$ spent in trial and error “repairs” and infinite frustration, the cold engine stall issue went unsolved.
The torque converter and more specifically the torque converter clutch (TCC) was suspected the culprit for this cold stall issue. However no one could come out with a sensible explanation and proof of what could be causing the failure so the problem went unsolved.
I have run across an article published in the Torque Converter Rebuilders Association (TCRA) August 2010 issue which describes what appears as the identification of the root cause and fix for this cold stall issue.

The research was sponsored by SONNAX who now manufactures and sells a simple Clutch Release Kit that can be fit in the TCC by a torque converter rebuilder:

I am still finding my way to have this kit mounted in my torque converter in Spain, so I have no personal feedback yet about its effectivity in solving the issue but I thought you would be interested.
