corsa air temp display is showing --.- which Iam told indicates faulty sensor, got a new sensor and its still the same, checked the sockets and plugs along the front and they seem all plugged in - has anyone got any ideas where the fault could be. The sockets I have checked are the one the sensor plugs into and if you follow it along the front a second socket/plug near the nearside front. Have unplugged them and plugged them in again.
