Z4 engine problem? Advice please!

i believe its for emmissions.
this came on on mine 3 weeks ago, its ok to drive and thee is a good chance it will go out after a couple of days and not come on again - which is what mine did.
It's more than likely one of the sensors playing up, if its still on after a week take it to a dealer.

That is, as correctly stated, the "Check engine lamp" which means that the engine management system has detected and stored a fault in the memory. The car might go into limp mode, depending on what fault it has detected.
If this is the case, the ECU will work from an approximate value to carry out its calculations for fuelling and timing.
Any competant garage with a code reader should be able to download the fault code and tell you what triggered it.
It is usually safe to continue driving the car but treat it with respect until the fault is either rectified or the code reset and not recurring.

I had this three months ago and it was a faulty spark plug. It came on when using 3/4 to full throttle at higher revs. Switch the ignition on and off quickly clears it until next time. Failing that speak to BMW and make sure your car had the coils replaced in it's early days, coil failures can be common on these cars.

It can be almost any sensor on the engine. It could be either a lack of a signal from a sensor or an intermittent signal. If it drives normally it may be a glitch with a sensor and the ECU will reset and the mill light will go out. If it does, you'll miss out on knowing why it came on, so get it to a garage and get it on the diagnostic tool.
If it doesn't drive normally, lacking power and being 'fluffy' you're missing an important signal and the fuelling goes all to cock. It will default to a rich setting to prevent detonation, this will foul your plugs in time, so get it on the diagnostics as soon as you can.
