CALIBRE K40 Front Sensor Issue
I have had my 2012 C300 for 2 months now, it came equipped with the Calibre K40 radar system, it worked well while it worked but now my front sensor is completely inactive, only my rear sensor will go off. Has anyone encountered this issue? If so what is the solution? Help would be appreciated before I take it into the shop

the wireless were all garbage and I replaced everyone I did, the hardwire was better. make sure the connector is twisted on tight on the back of the sensor up front. if wireless you might have to pair it to the brain, which was the problem with those turds. if wireless look for 12v on the brown wire

It is actually hard wired, which I'm now glad based on what you just said. I will have to take a look again at the front sensor. I don't wanna screw it up which is why I'm asking, but you're saying the wire that goes into the front sensor twists in and twists out? If that's the case maybe it just needs to be cleaned because it's been one hell of a winter up here in the NY.
