Hello together, when I lock the vehicle (SL350 Built. 2004) over the remote control is after a few days the comfort battery unloaded. It is a Silverline AGM and new, the previous banner was therefore not at the end. If I leave the vehicle unlocked everything is good, the battery does not discharge. The alarm system, which is often described here as a causer, has not been triggered so far … Whether I should change the alarm siren anyway ? Thank you and best regards Werner
