If you don't want the garage to check it out, you can get a cheap OBDII scanner (I got mine from ebay costing $27 delivered), and do a scan. The X5 comes with a OBDII port where you can plug it in.
It'll then provide you the code(s) which you can search the CD that come with the unit (or the net) to see what's causing the "Check Engine" light to come on.
And if it's intermittent, the scanner can also clear all errors. But the light will come back on if the fault is still there.
If your car seems to run well and idle smoothly and the "Check Engine" light comes on, most common cause are worn out O2 sensors - part of your exhaust/emission system. But as mentioned above, it'll be hard to tell until you know the error code.
