Flaky shifting when cold...
'99 E320
There are so many threads on this that I really hated to just update one...
I had a common issue,
When the outside temp is cold, the trans seems to stay in first or seems to want to start out in a high gear and feels like it's slipping.
NO CEL
"D" not consistently lighting up
Problem goes away as the car warms up and the "D" indicator starts working.
I decided that the issue was probably that the shifter was cold and the old gear selector module was fussy until it warmed up.
So.... I opened the console heating vent (the one inside the console) thinking maybe warm air moving thru the duct would heat the module.
And it worked! ever since I opened the vent, no issues (it was 19 degrees when I left the house today.)
Give it a try, it might work for you!

Please read the thread I have copied below - pre-facelift - replacement of the gear selector switch is a deeper fix if you ever need to go there:

In your 99 W210 - the gear recognition switch is replaceable without major hassle - like a $120 for the genuine MB part.
The cold weather "like-limp-home-mode" below freezing is a symptom - once other possible causes are eliminated - switch replacement is relatively straightforward for your car. Plug-n-play no recodeing required..
