My Ride: 2001 bmw 330xi
After 4 and half hours I finally just finished replacing my expansion tank, water pump, thermostat and hoses as well as lower hose temp sensor and fluid level sensor under the exp tank. Now the low coolant indicator light is on the dash. I put back the old fluid level sensor and the dash light is still on, coolant level is full. I bled the system for air, the heat is working fine in the car. Has anybody have any ideas what is wrong? Thanks.
