Since I have had a completely empty battery in the last few weeks 2 times in the morning (with all the theatre due to starting aid ADAC and so from the engine compartment, since even the boot or the automatic selector lever did not work anymore), I would like to change the battery now. I have to find out that I can not even expand the battery. The maintenance booklet describes very lapidary that nut the bracket should be loosened and removed, but: I cannot discover any bracket, the battery sits as if cast in her place, nowhere to see a fastening. Behind there is still a plastic / foam covered part that I can not identify (floor heating? a part for the air suspension?). Can someone with a same model (S 320 CDI L, full equipment) please give me a tip on how the battery is removed? Many thanks to all and many greetings King Lion
