M fault codes

Well I guess the question has to be firstly, was this a random check for the hell of it, or is the car actually doing something different which made you look.
If you only found them on a whim then reset and see if they come back.
If you checked for a reason then telling us the symptoms would be useful.

Car was low on fuel and I accelerated hard
It went into limp mode straight away with a restriction in supply
Pulled over ignition off and back on and it cleared
Put sone petrol in and drove fine even under hard acceleration
Then it’s come back three times since I haven’t cleared the faults
It’s an 07 Z4M

Looks like a TPS sensor to me for at least one if not all of those error codes.
One on top of the engine facing you and one underneath the airbox. Personally I would change both if they've never been changed, the one under the airbox is more likely to fail (more heat down there), but I've had the top one fail as well before.
Not too expensive these days and easy-ish to fit. Plenty of Youtube's / how to's on it
