I have a 2006 BMW X3. The coolant sensor is lighting up in absence of a problem. What's the problem?

Asked by TWMB Nov 03, 2014 at 05:24 PM about the 2006 BMW 3 Series

Question type: Maintenance & Repair

I replaced the sensor a month ago and it was fine for about 3 weeks and is now lighting up again.  It's intermittent, but on more often now.  Each time I've checked the coolant, it's been full and no evidence of a problem.  I've not been able to link the light coming on with speed, incline, engine warm or otherwise; only that it's never on when I start the engine. I suppose it could be a defective sensor but could it be something else?  Thanks!

That new sensor itself could be faulty, parts that are not oem replacment parts have a higher failure rate.
