BMW 3 E93 Convertible Comfort Module Installation

The module only uses functions which were originally built into the vehicle. All data relevant to convertible top control (e.g. limit switches, window position, speed) will be continuously monitored. All OEM safety functions (under / over voltage cut-off, thermal protection, etc.) remain intact.

The module's functional scope and operation:
• Tap function for the top's switch:
Now you need only to tap (>2s) with your finger on the convertible top switch, then the top will automatically open or close. This automatic operation can be interrupted at any time by simply tapping on the switch again in the opposite direction. When the top switch is tapped again in the same direction while the roof moves, the windows will stay open at the end of the roof movement. You can start the top's operation, pull out the ignition key, get out of the car and lock it – the top will continue to automatically close or open without the ignition.
• Operating the top while driving (up to a speed of 50 km/h maximum):
Up to a pre-programmed speed (though not greater than 50 km/h), you can operate the top while driving.
• Threshold speed adjustment:
Press the central switch for the window lifts in the drivers door in direction “close“ for >4s (windows must be closed) and the current speed will be set as new threshold limit. An acoustic signal will be sounded as confirmation that the new speed has been set. The maximum threshold speed is 50Km/h. The default programmed speed is 50Km/h for a new module.
• Operating the top per OEM remote control:
Press the Open switch on the remote control >3s and the top will open automatically. Closing the top works in the same way except that the Close button on the remote control is used. When the switch is pressed again in the same direction while the roof moves, the windows will stay open at the end of the roof movement. As a safety precaution, opening the top can be terminated with the Close button or closing the top can be terminated with the Open button. You can start the top's operation, start the engine and drive away while the top is still moving – it will continue the movement until it’s opened/closed completely.
• Battery Safe Function:
The module will go to power down mode automatically when it is not needed. It will then consume less then 0,2mA – that means that the battery.
