I currently own an 57 plate 1.9TDI A3 Sportback - during the recent cold snap we have had i've started to experience problems starting the car. The engine turns over fine but just does not seem to fire. This never seems to happen from a cold start but usually after I have had the car running, turned the engine off and then tried to start it again. After a couple of times trying to start the car the battery dies. If I get a jump start the car fires up fine. I've not done anything to the car recently so can't think what is going on i'm a little reluctant to fork out on a new battery if there is something else amiss. Does anyone have any ideas?
