Hello again :)

How do I tell which plug on the loom is which? they both sit next to each other, both the same design/fitment and both have 3 wires of exactly the same colours...? Doesn't seem the best bit of thinking on BMWs part this time?

TIA!

you could continuity check them to the correct ecu pin and mark one of them for next time or only disconnect one at a time.

It's the one furthest from the intake.

Pin 48 on the ECU connector go's to the middle pin of the connector if you want to test.
