Description
Listed here is OEM part 3D0907401 — a genuine used, tested Engine ECU Control Module for the Volkswagen Phaeton (2002–2016), Volkswagen’s flagship luxury saloon built on the exclusive D1 platform. Offered with V8 petrol, W12 petrol, and V10 TDI diesel powertrains, the Phaeton was among the most technically complex vehicles Volkswagen ever produced, and its engine management systems reflect that ambition.
The Phaeton’s ECU manages an advanced multi-cylinder injection strategy tailored to the 3.0 TDI or V10 TDI diesel architecture, controlling high-pressure common rail injection events, two-stage turbocharger sequencing, active engine mounts, and the coordinated emissions management systems required for a large-displacement luxury diesel. The complexity of this management system demands a properly functioning OEM control unit.
Failure of the Phaeton’s engine ECU is a serious event that can cause complete inability to start, loss of all engine power modes, erratic torque delivery across the rev range, disabling of the adaptive air suspension interaction, or a cascade of fault codes across multiple control modules linked via the Phaeton’s CAN bus architecture.
This unit was carefully recovered from a written-off Phaeton and tested against the 3D0907401 specification prior to despatch. Given the Phaeton’s sophisticated electronics, installation must be carried out by a VW-trained specialist or luxury vehicle auto-electrician with access to factory-level diagnostic equipment. ECU coding is required. A 14-day return period 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.
