04 2.0 Flat battery x 2 - Dawsy
after standing in the snow for 3 days - flat battery. Due to the age of battery fitted a new one. Did a good 200 mile journey - car stood another 4 days - flat battery. this is a diesel car and have read somewhere there is a fuel heater - could this be the reason. Has this happened to anyone else and does anyone have any ideas as to why this has happened.

Either it isn't charging properly or something is draining it. Connect a voltmeter across the battery, it should read about 12 volts when not running and about 14 volts running. If that is OK, disconnect one battery terminal and connect the meter between the battery terminal and lead with the meter on the amps range, if it reads more than about 100ma something is draining the battery - dont try and start the car with the meter in circuit.
