Roof Control Panel E70, E81, E87, E90, E91, E92, E93: Introduction
Prior to the introduction of the roof control panel, the wiring in the roof was extremely complex. Individual lines were required for the following functions:
- Interior lighting (front and rear)
- Sliding/tilting sunroof
- Anti-theft alarm system
- Lighting for make-up mirrors
- Electrochromic interior mirror with connection for electrochromic exterior mirrors
- Rain-light sensor or rain-light solar sensor
- Condensation sensor
Both basic and High variants of the roof control panel are available.
The High variant of the roof control panel is fitted in conjunction with specific optional equipment: e.g. sliding/tilting sunroof or with option 563 "Lighting kit".
The roof control panel optimizes the wiring in the roof as follows:
- The roof control panel is the interface for the wiring in the roof.
- The roof control panel also features other components, depending on the equipment fitted and the national version:
- Sliding/tilting sunroof switch
- Emergency call button
- Microphone
- Indicator lamp for front-passenger airbag deactivation
- Ultrasonic interior motion sensor (E70 only)
This summary of wires and components in the roof control panel optimizes the previous construction.
