I have not used my polo for over a year and the battery is dead, i have tried jump leads but still nothing. my next step is to change the battery, however on looking at the battery i have discovered that there is a small box ontop of the battery holding various wires (possibly the electrics for lights, radio etc) I would be grateful if someone could give me an idiots guide on how to change this battery. the vehicle is vw polo 1.4 cl 1998. my other problem is i have tried to move the car by pushing it, however the brakes have stuck (though i did leave the hand brake off throughout the year), can anyone confirm if the brakes could become damaged. you help and advise in this matter would be great.
