Description
Part number 8510832-01 identifies this Engine ECU Control Module, a genuine BMW component produced for the E90 3 Series. Recovered from a written-off donor vehicle and subjected to thorough testing prior to listing, this used module provides an authentic, cost-effective solution for E90 engine management restoration.
The E90 3 Series ECM processes throttle pedal input, crankshaft and camshaft position signals, and intake manifold pressure data to manage fuel injection timing, spark advance, and VANOS variable valve timing actuation. Precise management of these functions sustains the E90’s characteristically sharp throttle response and fuel efficiency across mixed driving conditions.
ECM deterioration in the E90 3 Series is often signalled by a hesitant or jerky throttle response, rough idle, intermittent misfires logged against specific cylinders, and a check engine light that recurs after being cleared. Some owners report reduced torque output especially at lower revs, or the vehicle defaulting to limp-home mode with restricted power output.
This part is sold used and tested — verify OEM number 8510832-01 is the correct reference for your E90 specification before ordering. Professional installation is recommended, and coding or adaptation to your vehicle’s DME will likely be required after fitting. A 14-day return policy applies to this item.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
