I would start by removing the plastic pipe you removed when replacing the MAF to verify that the rubber seal on the turbo inlet that the plastic hose fits over is intact and fitted correctly. If there is an air gap the engine ECU will be seeing LESS air from the MAF due to it getting air from a leak = less fuel = less performance. These engines run in open loop - there is no oxygen sensor in the exhaust pipe so the ECU will not be aware of un-burnt fuel. I have a 2003 Giverny green TD6 like you.
Transport mode is when the factory code the vehicle prior to shipping to save battery power - no radio and other features disabled. Easily changed if you have access to relevant software - i.e. BMW INPA, if not any BMW/Land Rover specialist will be able to change the mode
The issue between 12 then dieing 3... Id say is your issue with transporter mode. Deal only fix at one point . Unless you know someone with the software.

Perhaps you could have cleaned your old air mass flow sensor with an electric contact spray cleaner and not bothered to buy a used one 🤷🏾♂️
I could have but the plastic casing was broken on the old one so it needed replacing really.
