Hi from new user. Bought my new Insignia 2.0 ltr cdti a few weeks back. But having problems when cold. The tick over is too high at about 1100 rpm. This makes driving a bit of a nightmare. Especially when cold. Have turned the heater fan down completely and this seems to work for a bit. Have read somewhere that turning heater level down to 18 helps but that doesn't work either. Windscreen mists up when fan reduced as well so a waste of time there. Just wondering what the problem could be and if this idle speed can be reduced to normal 900rpm just like my other diesel cars. Any suggestions. There's nothing in the hand book and dealer says it's normal. Oh Yeh. Something to do with pre heating they said.
I'm not convinced. Thanks in anticipation.
