my car is throwing white smoke when it is warmed up on idles at stop lights it happens randomly it is quite embarrassing to cover the car in back of me with a big cloud, don't think its the head gaskets because car idles fine and runs great what do you guys think?
Any recommendations to mechanics in San Diego i was going to go to Cunningham bmw
I drive says increased emissions.

White smoke usually means coolant is getting into the exhaust - which is commonly caused by a failed head gasket.
Check your coolant level IN THE RADIATOR, not the overflow tank to see if its low.

OMG!!
First, WAIT FOR THE ENGINE TO COOL. Then open the radiator cap. If filled properly it should be just about full (a small amount of coolant may drip out). If you can't see any coolant and the radiator core is plainly visible then you are missing coolant.
Plase don't tell me the radiators in these cars don't have caps on them......

Wow! I REALLY need to start looking under the hood more often 
Normally, an expansion tank bleeds off excess fluid from the radiator when the pressure reaches a certain point. The pressure relief mechanism is actually built in to the radiator cap. So if there is no cap then what opens/closes to allow for the coolant to go in/out of the expansion tank?

When I refilled the expansion tank, I was wondering how can I be sure that the fluid is flowing through the radiator but I guess I-drive detects it somehow and also squeezing the 2 large hoses on both sides of the pump did confirm there were some hot fluid moving through the hoses.
