    incoming air temp control

    my 1.6 is using losing about 50 miles per tank of fuel on a motorway/a road run when the outside temp is quite cold(early morning/late evening). I know about cold air is denser etc but was wondering if the incoming air temp is controlled at all by being directed past exhaust manifold etc as some cars do and its controlled by a bi-metallic flap.
    I know that the 1.6 is a bit crap anyway, heavy car etc but I would at least expect consistent mpg.

    Any ideas.

    I dont think injector cars tend to do that nowadays. It used to happen on old cars with carbs to stop "carb icing" and so stalling on idle. Maybe with the cold weather the enrichment is staying on longer. Have you checked the coolant temp sensor incase it is giving dodgy readings to the ECU, they have a habit of going.

    would that show up on a ecu scan as it went to audi to be checked etc and the scan turned up nothing.
    they did decoke it though which made no difference, charge me for the privilege as that was'nt under warranty

    going back to the cold weather enrichment, how does that work? is it all via ecu with info from the coolant temp sensor?
    how could i check if this sensor works ok
