I have a Volkswagen Polo. The problem is that it is not getting started sometimes. But sometimes it's get ignited without any problem. I took it to the service centre of Volkswagen. They just tried to start it and without any inspection told me that my car battery is nearly dead. But here is something contradictory which I noted. After remaining parked for even days my cars starts without any problem. But when I drive it and then stop anywhere and switch off the engine then it won't start. So if battery is nearly dead how is it possible that it is getting started without a problem after long standing but not after driving. Moreover when it doesnt start the brakes are heavily jammed. And are not pressable.
