Roof Module - BMW 3-series convertible Complete Vehicle Workbook

Roof Module

The roof module consists of 3 roof panels, linkage, main mount and the hydraulics. The movement sequence of the retractable hardtop is
driven by a central hydraulic system with hydraulic 8-cylinder activation, with an additional 2 gas pressure dampers in the main mount.
A total of 8 hydraulic cylinders and 6 gas pressure dampers are used in the retractable hardtop. The hydraulic system is controlled via the
Convertible top module (CTM) and is built into a multifunctional tray in the luggage compartment floor.
A central electric motor in the front roof panel serves to lock the entire retractable hardtop system. The roof shells are interlocked using
drive cable tubes, similar to a sunroof drive. The roof module weighs about 215 lbs (approximately 95 lbs. more than a soft top)
