I have a 51 plate polo 1.4 which has previously had no problems. For about 3-4 weeks now, it keeps draining the battery. At first i thought it was me leaving something switched on/the door slightly open. Following a few charges of the battery it was replaced with another battery to see if this was the trouble. At first it would take about week before the charge would go again. Last night i replaced the fully charged battery and it managed to drain it straight away!

How is this possible? Has anyone else had the same/a similar problem. Please help this is soooo frustrating!
