Low coolant light comes on for 1 minute after start

[Turbo951]

Hello:

I have a 2002 325xi. For the past several days when I first start the car, the yellow low coolant light comes on until the car warms up. I looked at the coolant overflow tank to see the level and it's slightly above the minimum mark. Any ideas what could be causing this? The car has never overheated nor has it gone over the middle mark on the temp gague. Any help would be apprciated.

Thanks!

Brett

Ever flushed the coolant?

Time to eat $160 at the dealer.

The same thing has been happening to my 2002 325I for a week or so. Did you get the situation resolved?

The coolant sensor is located in the bottom of the expansion tank, it is known to foul and/or fail and cause this problem. If the level is OK, you can remove and clean or replace the sensor.
