  • 2018 Insignia B 2.0 cdti 6 speed manual Idle Speed. I

    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.

      Hi,

      Dealers will say anything to fob you off. Doesn't sound right though.

          Hi to all. Here's an update for my post. Firstly thanks for all your comments. Have found out that the new Insignia diesel has a fast warm up cycle. This takes the idle speed up to 1100 rpm. To lower the idle you have to knock the heater down to below 16 degrees. Also turn the fan off. Thus cancels out the fast warm up. Once the engine has warmed up to about 1/4 I can turn everything up. Such a stupid idea. If only GM had left things as they were with the previous model. Obviously the petrol models are unaffected including the new 1.5ltr. Thanks to all for the advice and I hope that what I've found out will help new prospective buyers out with their choice of new car. Cheers.

            That's a new one....Thanks for letting us know. I'm sure the same question will be asked again at some point.
