Thanks Ghost. Sounds like you're saying the tank may also need to be replaced, not just the sensor. I tend to agree...……not worth the trouble. Even though a new tank and sensor isn't very costly, I check fluids and pressures regularly anyway.
My '08 L322 with 89k miles displays the "Check Coolant Level" message. The coolant level is fine, and I recently installed a new sensor at the bottom of the expansion tank as recommended to cure this common problem...….but the message still come on.
Any ideas why?
Thanks.
