Overview

BMW MSD80 ECU Repair & Replacement Service (N54 Engines)

We specialise in BMW MSD80 ECU repair and replacement for N54-powered models, including:
135i, 335i, 1M, X6, and 740i.

The MSD80 ECU is well-known for MOSFET and internal power circuit failures, which can cause injector faults, misfires, or complete no-start issues. 

How It Works

  1. Send us your original ECU, CAS, and key.

  2. Once received, we will repair or replace your ECU — typically same or next business day.

  3. Your repaired or replacement ECU, CAS, and key will then be dispatched back to you immediately.

Optional Add-Ons

You can select additional services at checkout, such as:

  • Extra key / remote programmed (Blank manual blade will be included as well, not cut)

  • Stage 1 ECU tune (for improved performance) No engine modifications are required, suits a stock vehicle with automatic transmission only.
