I used my XF last wednesday and evething was fine. Parked it in the garage as usual. Friday morning since it was a nice day, I decided to go to work with my XF but the engine would not crank. Just hear cllic, clic from the starter. Jumped in my other car to go to work. Saturday I charged the battery. It was not very long to get fully charged, says about 45 minutes. Tried to start and again clic,clic. I left the keys at run position to check the lights in the dashboard and I noticed that the spoiler was lifting by itself? Never had this before.

The car has 82 000KM or around 51 000 miles on it. All the service maintenace have been done as required. The battery is about two years old. The starter and alternator are original, What could be the problem?
