So the MU was replaced, but the symptoms continued to persist.
The decision was made to replace the clutch plates in the MCT and service the wet clutch.
After doing all that, the car was returned and the symptoms were gone.. for a few days before returning. The lack of creep upon cold start in D came back but was again only every few start ups, and there was no more jolting.
In the end we are going to replace the wet clutch and hopefully resolve all these issues.
Was Xentry used for a diagnostic etc ?
MB or free car repair shop ?
Sounds expensive and tedious to solve the problem.

Xentry was used for all the diagnostics, as well as all the adaptation live/standstill things.
Doing this at an independent workshop, as the only authorized dealer in my country charges many multiples more than what I am paying - not including how long it would have taken them to give me a slot and diagnose the problem.
I want to keep this car for as long as possible, so as long as she comes back working well - money can be replaced

okay i understand.
Is your shop specialised to automatic transmission or a normal car shop ?
How much milage (miles/ km) has your car ?
Sonds like you have a 9G ( or 7G ) ?

I'm only at 61500 km - live in a small city state so not much opportunity for long roadtrips. The tropical climate + stop/go traffic probably contributed to faster wear and tear on the components.
I have the 9G
