Frequently Asked Questions

What is a BMW DME MOSFET failure?

The DME (engine computer) uses MOSFET transistors to drive components such as the injectors. When one fails, the DME can no longer drive that circuit, causing misfires or related fault codes on one or more cylinders.

Which BMWs use the MSD80 DME?

The Siemens MSD80/MSD81 is used on many N43, N53 and N54 equipped BMWs, including E9x and other E-series models.

Does a repaired DME need programming?

Repairing your own DME keeps its software, coding and immobilizer data, so it normally goes back in without re-programming.
