Hi There,

I recently drained and refilled with fresh g12 coolant. Car warmed up fine and level fine also. Approx a week later engine managemant light
came on. Did a scan and found g62 implausible signal. I replaced a green sensor with another from GSK and cleared fault. Nowengine managemant light is back again with g62 implausible signal.

Would draining the coolant have caused this in anyway?

Any thoughts, many thanks,

Sean
