Any idea what these warning lights mean?

I know what each light is of course, but seems strange they should have all just come on together?

Traction control wasn't turned off - the light came on itself.

Switching off and on again didn't make them go away...

I've got a warranty with breakdown so is it time to ring BMW or DIY troubleshooting?

Yes I know it needs a good dusting

I would start by looking at the ABS rings and sensors. All those things use the ABS sensors.

Just had a quick look in the manual (online through my signature if you want them) and it seems that the brake, ABS and DSC lights all at once mean there has been a DSC failure. Car is still driveable but get it checked.

Usually down to crud on the sensor or the steering angle sensor needing to be reset. You can do that with a few lock to lock turns.

Ok thanks all - I'll try the lock to lock turns and if that doesn't sort it then it's a call to BMW.

25mpg from a Z4M? How?

When these lights came on together on mine, it ran like an absolute dog. After switching off the ignition for half an hour it cleared and ran normally. Only error code that was stored and recognised by my OBD II reader related to mass air flow. It's been fine since and I've driven thousands of miles in the intervening period and there are no further error codes...
