Descriere
Carrying OEM number 8D0907557H, this genuine Audi A4 B5 Engine ECU Control Module has been carefully sourced from a written-off B5 platform vehicle. Bench-tested to confirm it operates within the original manufacturer parameters, it is listed here ready for professional installation.
On the A4 B5, the 8D0907557 series ECU governs fuel injection quantity and timing, spark advance, throttle response, cold-start enrichment, and evaporative emissions purge control. Diesel engine variants use Bosch EDC15 management for injection and boost mapping, while petrol units operate through the Bosch Motronic ME7 framework.
When an A4 B5 ECU begins to fail, drivers often notice unexplained check engine warnings, erratic fuel economy, hesitation on acceleration, persistent misfires across multiple cylinders, difficulty restarting after a warm soak, or a no-communication fault with the ECU during a diagnostic session.
This unit is used and thoroughly tested. Verify OEM number 8D0907557H matches your car’s engine code and model year before purchase. Professional fitting is essential. Post-installation VCDS adaptation, injection quantity coding, and immobiliser alignment will be required. 14-day returns accepted.
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.
