2004–2010 BMW 645Ci 650i M6 Convertible Top Hydraulic Motor Pump w/ Cylinders & Cables OEM

Restore reliable, factory-correct convertible top operation on your BMW 6 Series with this genuine OEM hydraulic pump assembly, complete with the original cylinders and lines.

This is the complete hydraulic power unit that raises and lowers the folding soft top on the E63/E64-chassis BMW 6 Series — the pump motor, hydraulic cylinders, and connecting lines as a single assembly, not a bare pump. It retains the original mounting configuration and hydraulic circuit design used across the 645Ci, 650i, and M6 convertible.

Pre-owned genuine OEM unit, pulled from a single donor vehicle. May show normal cosmetic wear from age and prior installation. You will receive the exact unit shown, not a stock photo or substitute unit.

Verify Fitment Before Ordering

The E63/E64 platform used this hydraulic pump assembly consistently across 645Ci, 650i, and M6 convertible trims for this year range — but always confirm against your vehicle before ordering. For additional fitment support, send us your VIN and a clear photo of your original pump's part number or connector before ordering.

Why Choose a Genuine OEM BMW Convertible Top Pump?

• Matches factory hydraulic pressure and cycle timing exactly
• Original electrical connectors — no rewiring or adapter needed
• Correct mounting geometry for a proper reinstall
• More straightforward installation than piecing together aftermarket cylinders and a separate pump

This is a single-unit assembly pulled from one donor vehicle — once sold, we may not see another complete kit like it.

Installation

Professional installation is recommended — this is a hydraulic system integrated with the vehicle's Convertible Top Module (CVM), not a bolt-and-go part.

A convertible top that won't open or close isn't always the pump. On this platform it's commonly the rotation sensor misreading position, a Convertible Top Module fault, or a window alignment/seal switch issue — all of which can throw the same "top not locked" symptom as a failed pump. Confirm the pump and cylinders are actually the fault, not the sensor or module, before ordering.
