It might be a faulty power steering pump. Try checking the level of the power steering fluid. It is probably best you have your power steering system checked by a mechanic.
Does the noise occur only when the vehicle is moving?
Try moving the steering wheel from side to side, while stationary (but don't do it too often, or you might damage something). If the noise is still present when the car is stationary, then it probably is the power steering system.
If the noise only occurs while the vehicle is moving, it could be a problem with the differential/final drive, or even wheel bearings.

On the instrument cluster in the center there are two buttons (clock and s/r) .Press and hold the s/r (i think thats whats on the button) and turn the key to the first position. at first it will say TEST in the cluster. keep holding the s/r button and it will flash to your SIA (service meter) release the button and press and hold until it says reset (or reset flashes) and then press again. just play with it im going off of memory. just dont be afraid. as usual im sure your local bmw dealership would be glad to help

at the engine, there is a small sensor that helps increase or decrease the rpm of the engine. Perhaps yours is soo low, that when you slow down, it's almost about to stop.
The other problem could be the airfilter sensor. If it's not properly fixed or if the sensor itself is a bit damaged, than the engine is not getting enough air and so, let's the engine almost go off.
Please give further details if this has not helped.
