Engine ECU Control Module 1430273 BMW E46 – OEM Used & Tested

Descriere

This engine ECU control module carries OEM number 1430273 and is a genuine used, tested unit for the BMW E46 — the third-generation 3 Series produced across saloon, touring, coupe, compact, and convertible variants. Extracted from a written-off donor vehicle, it has been cross-referenced against original factory specification data.\n\nThe ECU processes high-frequency sensor data — from the crankshaft position encoder, map sensor, and intake air temperature probe — to compute precise injection timing and fuel quantity for each cylinder. It additionally controls the VANOS variable camshaft advance mechanism on equipped engines to broaden torque delivery and reduce exhaust emissions.\n\nA defective ECU on the E46 commonly presents as cylinders misfiring at idle or under partial load, a cold-start idle that refuses to stabilise, hesitation when pressing the throttle from low speed, and an engine management light that returns shortly after fault codes have been cleared.\n\nOffered as a genuine used and tested part, this ECU is identified by OEM number 1430273. Verify this number against your exact E46 engine variant and model year prior to ordering. Installation should be performed by a qualified BMW technician, and software adaptation or VIN coding will be required after the module is fitted. A 14-day return policy is in place.
