Engine Computer Repair

Expert Engine Computer (DME / ECU) Repair Services

The Engine Control Unit (ECU), also known in German vehicles as the Digital Motor Electronics (DME), is the absolute brain of your engine. It dictates ignition timing, fuel injection, and turbocharger boost. When the engine computer suffers an internal hardware failure, your vehicle will suffer from persistent engine misfires, lack of power, or an inability to start at all. Diagnosing a failed ECU can be incredibly frustrating, and replacing it at a dealership is often prohibitively expensive.

Our engine computer repair service focuses on deep, component-level restoration. We don’t just patch software; we replace the burned-out MOSFETs, blown capacitors, and damaged ignition coil drivers inside your factory ECU.

Specializing in BMW & MINI DME Repairs

While we handle a variety of engine computers, our lab specializes in high-performance European engine management systems, which are known for specific, recurring hardware faults. Our core services include:

  • BMW N54 MSD80 DME Repair: A permanent rebuild service for the notoriously fragile MSD80 engine computer used in the 135i, 335i, and 535i. We fix internal hardware faults that cause chronic cylinder misfires (commonly cylinders 1, 2, or 3) and blown ignition coil drivers.
  • Bosch MEVD Series Repair: Specialized component-level repair for the Bosch MEVD17.2.6 (BMW N55 engine) and MEVD17.2.2 (MINI Cooper S / Countryman). We diagnose and repair specific internal circuit breaks caused by heat and vibration.

Why Trust Us With Your ECU?
