Description
OEM number 4B2907401E — this is a genuine Audi A6 C5 Engine ECU Control Module recovered from a written-off example. Each unit is checked against original manufacturer data and dispatched only after passing full functionality tests.
The A6 C5 platform used Bosch Motronic ME7.1 management across its petrol range, coordinating fuel injection, ignition timing, torque output, and throttle response. This ECM handles real-time sensor data from the MAF, lambda, and knock sensors to maintain optimal combustion.
A failing ECU on the A6 C5 can produce hard starts, rough idling, misfires, unexpected limp-mode, or a persistent engine management light with fuel-trim or sensor fault codes stored.
This unit is used and fully tested. Always confirm the OEM number 4B2907401E matches your vehicle before ordering. Professional installation is strongly recommended. Coding or VCDS adaptation to the vehicle may 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.
