Original BMW Micro Power Module (MPM) Control Unit for 5 Series, 6 Series, M5, and M6 (2004–2006)

On 2004–2006 BMW 5 and 6 Series cars, including the M5 and M6, the Original BMW Micro Power Module 61-35-9-266-274 is the trunk-mounted control unit that supplies power to the radio, navigation, and LCD screen systems and puts the car's electrical system to sleep when it is switched off. A power module like this sits between the vehicle's supply and the systems it feeds, switching them as the car wakes and shuts down. BMW names it the control unit Micro Power Module, usually shortened to MPM. The current number has been in production since December 2011, is made in Germany, and is sold individually.

Original BMW Parts, including this module, carry a 24-month parts warranty.

BMW rates this number as bilaterally exchangeable with the earlier 61-35-6-982-347, meaning either part can stand in for the other. The same module also replaces 61-35-6-937-010, 61-35-6-966-270, 61-35-6-938-358, and 61-35-6-939-655, so an old unit carrying any of those numbers takes this part. BMW applies the module to the E60 sedan and E61 wagon 5 Series and the E63 coupe and E64 convertible 6 Series, across M54, N52, N62, N62N, and S85 engines.

Common Questions

Why do Micro Power Modules fail?
Most fail from water intrusion. The module sits in the trunk, where water can get in and reach it.

My car has a body gateway module behind the glove box. Does it need this part?
No. Because of these water-related failures, BMW redesigned the electrical system on E60 and E63/E64 models and replaced the Micro Power Module with a body gateway module behind the glove box, so cars built after that change do not use an MPM.

PMB Performance can help sort out MPM questions on E60, E61, E63, and E64 cars before you buy.
