Original BMW Convertible Top Control Module for BMW Z4 E85 Roadster and M Roadster (2003–2008)

This Original BMW convertible top control module, which BMW calls the folding top module, controls the movement of the soft top on the E85 BMW Z4 Roadster and M Roadster from 2003–2008. A top module of this kind reads the driver's top switch and commands the drive that raises and lowers the roof, so the full open and close sequence depends on it. BMW shows this version in production from November 2007 onward. It is made in Germany and sold as a single module. When a Z4 top stops operating correctly, this module is one of the parts that can be behind the problem.

As with every Original BMW Part, this module is backed by a 24-month parts warranty.

This module is cross-referenced to several earlier part numbers. Part number 61-35-7-199-997 replaces 61-35-7-199-819, and it also cross-references to the earlier numbers 61-35-6-925-897, 61-35-6-936-801, 61-35-6-943-232, 61-35-6-947-655, 61-35-6-954-776, and 61-35-6-986-879. If the label on the module in your car shows any of those numbers, this is the current part that takes its place. Send us your VIN and we will confirm the right module for your Roadster.

Common Questions

Will this fit a 2004 Z4 Roadster built before November 2007?
Yes. BMW marks it as retrospectively interchangeable with the earlier 61-35-7-199-819, so it fits Roadsters built before this version entered production.

Does the M Roadster use a different top module than the 3.0i and 3.0si?
No. The S54-powered M Roadster uses this same part number as the six-cylinder Roadsters.
