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!
