Review on URO Parts 61 360 855 by Jason Porter

It fits nicely in my aluminum Zionsville coolant surge tank for my e39 540i and there is no sign of a leak. BUT, the sensor stopped working a week after installation. I now get a constant low coolant warning in my cluster when turning the car on or off, even when the coolant level is more than high enough. Obviously these sensors fail very, very often, but I think the Uro version is no exception.
