N55 ECU Engine Control Module — F10 535i / F25 X3 — Overview

When your N55's ECU fails, the symptoms hit fast — rough running, limp mode, persistent fault codes, and a car that simply won't perform the way it should. This direct-fit replacement Engine Control Module, carrying OEM reference numbers 7629420 and 0261S07331, is engineered to restore full factory-level management of fuel injection, ignition timing, and power delivery to your BMW's turbocharged inline-six without the steep cost of a dealership unit.

Built specifically for the F10 535i and the 2011 F25 X3, this module slots into the existing ECU mounting location and reconnects to the factory wiring harness without modification. Once properly coded to your vehicle's VIN, it resumes adaptive parameter management across all driving modes — keeping the N55's characteristic balance of efficiency and thrust intact, whether you're cruising on the highway or pushing through mountain switchbacks.

The onboard diagnostic architecture is retained in full, meaning your shop's scan tool will communicate with the module just as it would with the original unit. Fault identification stays fast and accurate, reducing diagnostic time and getting your car back in service sooner. Each unit is subjected to a quality inspection prior to shipping to verify it meets the electrical and functional standards the N55 platform demands.

Important installation note: ECU replacement on BMW vehicles requires VIN-specific coding to align the module with your car's immobilizer, transmission, and peripheral systems. Professional installation by a BMW-trained technician or a shop equipped with ISTA or compatible coding software is strongly recommended. Skipping this step will result in a no-start condition or limited functionality regardless of module quality.
