It could mean that you are low on anti freeze. Or if you do not have a temp gauge it could mean that the engine is getting hot.I would look in the owners manual if you have it and it should give you a much more detailed description of what it means.

A yellow explanation point symbol on the dashboard typically applies to the Tire Pressure Monitoring system. A thick ! inside a half drawn flat tire symbol to be complete and comes in yellow color when lit. Under normal vehicle set-up, if this indicator stays lit after the power-on selftest, you need to check your tires for any uneven pressures and adjust their pressures to correct specifications. Okay? : )
A red exclamation point inside a circle when lit indicates your parking brake is on, or your brake fluid level is low.
The below is taken from another site written a year ago:
What you are looking at is the Service Indicator. The green, yellow and red lights let you know when service needs to be performed. The green lights mean everything is still good. The yellow lights mean "anytime you're ready." The red lights mean do the service ASAP. There are also two other lighted areas. One says "inspection," the other says "oil change" (or oil service.) An oil change is an oil change. However, there are two inspections: Inspection 1 is normally at every other 15,000 miles; Inspections 2 is at every 30,000 miles. Your local BMW dealer should have a pamphlet listing all duties performed for each of the services. Inspection 2 can run you around $400-$800 depending on the service station/dealership's labor rates. Inspections 1 should be around 1/2 of that. You should have your oil changed about every 5000 miles. Dealership oil changes can range from $35-$65. A BMW that is well taken care of will last a long time.
FYI, don't be surprised if the SI (service indicator) board decides to **** out one day. I'm surprised to see yours is still working (they usually die within 10 years unless someone went thru the expense to have it replaced.) If/when it does go, just gauge your services by the mileage intervals I've listed above. I'd also recommend when you stop into (or just call) the dealership, go to the parts department and order an owner's manual for your BMW. Should be less than $20 and get to you in about a week unless they have one in stock. When the service tech has performed the necessary service(s), he will reset your SI board so that only green lights are showing.
there can be a yellow light in the cluster that looks like a small radiator or box with waves inside of it to indicate water. This light means that the coolant level sensor has detected a low coolant level. Typically the expansion tanks inside of these cars will crack from heat and age. A simple diagnosis is to check your coolant level and top it off. Do not forget to bleed it by unscrewing the bleeder screw found on the upper radiator hose while filling up the reservoir found on the right hand side of the radiator. once the coolant has been filled, tighten the bleeder screw back down but be careful not to over tighten. and finally screw on the expansion tank cap. run the vehicle to operating temperature and use a flashlight to inspect the engine bay for leaks. If there is a leak, it will need to be repaired. possible leaks are a cracked expansion tank, leaking radiator hoses, or a leaking water pump or thermostat.
