@bowfer I admire your persistence.
But how much longer are you going to put up with a car that cannot maintain a core function such as the ability to go at the national speed limit? There appears to be no real support from MG to resolve this and they seem to just be stringing you along. It is not your job to fault find the issue nor to identify the cause or linkage with other factors. The garage needs to take the car back and resolve the issue whilst providing you with a suitable replacement in the interim.
The problem appears to be a very rare one (as opposed to the more common oil leak or undertray) and of greater immediate pain, so I suggest that your car is a one off lemon.
Personally if I were you I'd reject it. You have sufficient evidence to do so.
