i bought a diesel Kia Ceed 1.6 CRDI GS end of July last year and since then the battery has been run flat at least 4 times. Each time the car has been left standing for a few days. no lights or other electrics left on. i took it into the dealer who could not find a drain on the battery. there were some problems with the radio freezing and we took the fuse in and out again. the radio then worked fine and there was no more probs with battery for several weeks. then the battery was flat one morning (nothing left on). the dealer has had it for 2 weeks and cannot find the fault... Any ideas or suggestions much appreciated!
