Why does engine light flash blue when coolant and oil is OK on 2002 Beetle?

What engine light? Most of the time, the blue light is the highbeam on light. More information can be found in your owner's manual. If you do not have one, then I suggest you get one. You need an owner's manual to know what items to service and when, and for specifications. You can order one from a dealer, find one at a salvage yard, or eBay.
Answer
I took mine in twice to get it looked at and was finally told that it goes on when you first start the car but then eventually goes off. I was also told that blue lights don't mean anything and it's the orange one's you have to worry about. Answer The engine coolant light can show either blue or yellow. Blue indicates the engine is not up to temperature and yellow/amber indicates an overheat condition. If the indicator never leaves the blue state (goes dark) you should get the cooling system checked (stuck thermostat?) If it turns amber find a safe pull off and shut off the car and let it cool down. (stop car symbol in the owner's manual.)
Answer
If the coolant light is flashing blue it means that you have a faulty coolant sensor, there are two coolant sensors and one of them is very cheap and needs to be replaced. Do check your coolant level and make sure not to over fill, check when engine is cold.

Can lack of coolant cause check engine light to flash?
It depends on what you mean by going off and on. If it happens like a flashing light (check engine) It will not be low coolant. It usually mean that you have a random missfire and that it is bad enough of a missfire that it is damaging your catalytic converter. You need to get to an auto parts store that will check your trouble codes.
