My mini is dead ! After turning the engine off last night a fan came on and blasted away furiously. This often happenes but seemed to take longer than usual to stop but I left it assuming everything was OK. Ive just tried to get into the car this afternoon and the ingnition key wont open the car. Assuming the battery was dead ( drained by the fan last night ??) I opened the car with the spare key and my husband attempted to look at the battery. Suddenly the alarm has gone off and we dont know how to stop it !! We're noe waiting for the RAC to arrive ! Any ideas why the fan goes off and any ideas why my mini is dead ? Help !
