    Anyone else had this? Car is a 2004 A4 PD 130 Sport.

    Just started coming up when the weather has been really cold and the starter has to work harder. Brakes are no different in operation and there's plenty of life in the pads.

    I know diesels need a vacuum pump so wondered if it was not sensing vacuum quickly enough.
