Description
Part number 8E0907311E is a genuine used, tested Engine ECU Control Module for the Audi 80 (B4 platform, 1991–1996), a compact executive vehicle noted for its balanced handling, longitudinal engine layout, and the option of quattro permanent four-wheel drive. This ECU was originally manufactured to OEM standard for the Audi production line.
Acting as the brain of the engine management system, this module controls fuel injection duration, spark advance timing, exhaust gas recirculation interaction, and deceleration fuel cut-off. It continuously adjusts the air/fuel mixture using closed-loop feedback from the lambda probe, optimising both performance and emissions output.
A deteriorating ECU on the Audi 80 platform may cause symptoms including irregular idle oscillation, misfires under acceleration, poor cold-start response, or a sudden inability to start. The fault may not always trigger a clear diagnostic code, making ECU substitution a valid diagnostic step when sensors and wiring check out correctly.
This module was removed from a carefully selected written-off Audi 80 and tested prior to despatch to verify it meets the 8E0907311E OEM specification. Installation by an Audi-trained or qualified independent technician is recommended. Variant coding to the host vehicle may be required. Our 14-day return guarantee applies.
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.
