Hello, I’ve been driving a Mercedes SLK for quite some time now, because Mercedes doesn’t seem to get the serial error with the tightness in the trunk area I’m looking for help in this way. It can’t be that when it rains the trunk under the carpet is running full and then the complete control unit so to speak drains off. Maybe you can help me someone else without I’m out for a new control unit with installation again 600€. I need either a schematic of this module, a partial extension or at least the indication of the corresponding resistors. It is the central control unit of the central control unit of a Mercedes SLK 230 Kom. Bauj. 98/99 Greeting cmcloud
