RHD - UK, Small white plastic plug???

[GlynG]

On my 2020 M3P - UK, therefore right hand drive - I have noticed a small white electrical plug socket - its located underneath the dash close to the A post on the right hand side and on the same panel with the footwell light in it. Does anyone know what this is for?

Its the diagnostic port. Slightly different plug but afaik does the same thing as the port we tap in for smt under the rear airvent.
