Help: Engineer Coolant Codes: 19537 16502 17698

[fritzner]

The green top G62 coolant sensor was replaced 2 to 3 years ago with the coolant flange. Also did the 034Motorsports breather house kit.

The G62 sensor is a cheap fix, but its kind of a PITA to get to. So I wanted to poll you experts to see what you think.
I can hear my fans running when I first start the car. Otherwise it runs well and the gauge always ramps up to the middle as it should.

Does the G62 fail again or might it be something else? Codes below.

You can check the wires and see if any possible compromise to the integrity of the wiring, tampering wity the signal strength. Shot in the dark, but worth a check.
