Description
Carrying OEM reference 8D0907401F, this genuine Audi A4 B5 Engine ECU Control Module was recovered from a written-off B5 platform car. Bench-tested against the original manufacturer specifications, it has been confirmed operational and is ready for installation by a qualified technician.
This Motronic ME7 unit controls the full engine management cycle on the A4 B5 — spark advance, sequential injection, MAF-based load calculation, knock retard, and evaporative emissions. On automatic-equipped vehicles it also exchanges torque request data with the gearbox TCU to manage seamless power delivery.
Signs of ECU failure on the A4 B5 include an engine management light that will not clear, rough running particularly from cold, misfires on one or more cylinders, unexpected limp mode, or fault codes pointing to injector driver circuits or internal controller errors.
Sold as used and tested. Verify that OEM part number 8D0907401F matches your car’s engine code and model year before purchasing. Fitting by an experienced technician is recommended. Immobiliser coding via VCDS or a VAG specialist tool will be required. 14-day returns apply.
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.
