My Ride: 2007 328i coupe
I will have to add this(since it is my problem now)the LOWER RADIATOR HOSE TEMPERATURE SENSOR COOLANT!,I have a 2003 330ci A/T,the dash was constantly showing the lower coolant level warning light..it was hard to find,but today showed it was the culprit,the o ring in this sensor degraded and allowed a small amount of coolant to drip....my two cent here!
