Description
The part number 8E0907401 belongs to a genuine Audi A4 B6 Engine ECU Control Module. Sourced from a written-off donor car, this unit has undergone testing to confirm it meets the original operating parameters of the B6 platform before dispatch.
The A4 B6 petrol range relied on Bosch Motronic ME7.1 to manage spark timing, sequential fuel injection, idle stabilisation, and exhaust emissions. This ECM also communicates with the ABS, airbag, and gearbox modules across the vehicle CAN bus, forming the heart of the engine management network.
Symptoms pointing to a failing A4 B6 ECU include an illuminated engine warning light, stored fault codes for sensor driver stages, rough or lumpy idle, difficulty starting, unexpected stalling, or sudden loss of performance under load.
Sold as used and tested. Cross-reference OEM number 8E0907401 with your vehicle data before purchasing. Qualified technician installation is advised. Adaptation coding via VCDS or dealer diagnostics may be required after fitting. 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.
