Any help would be awesome.

Your car uses the Runflat indicator RPA system.
If a tyre loses pressure, its diameter changes. This in turn alters the rotational speed of the corresponding wheel. This is detected and reported as a flat tyre and is indicated by a Yellow light illuminating on the dashboard.
You should ensure all your tyre pressures are as required and then the system is initialised from the iDrive as follows:
>Vehicle information.
>Vehicle status.
>Perform test.
>Start the engine - do not drive off.
>Start the initialisation with "Perform reset".
>Drive off.
Initialising is completed while the vehicle is in motion.
The complete procedure is on page 102 of the UK owners handbook. Yours may be different.
