Description
OEM number 038906012C is a genuine Audi A3 1.9 TDI diesel Engine ECU Control Module — one of the most widely used VAG diesel management units. This example has been removed from a written-off donor vehicle and verified operational through bench testing.
Built around the Bosch EDC15 diesel management platform, this ECU governs fuel injection quantity and timing, EGR valve operation, boost pressure control, and glow-plug sequencing on the 1.9 TDI engine. It interprets signals from the MAF, rail pressure, and coolant temperature sensors to optimise diesel combustion.
Failure indicators on the 1.9 TDI include excessive black or white smoke, poor throttle response, rough running at idle, unexpected engine shutdown, or a stored ECU power stage fault code reported during diagnostic scanning.
This is a used and tested unit. Confirm that OEM reference 038906012C corresponds exactly to your vehicle variant before ordering. Professional fitting is recommended. Immobiliser coding and injection quantity adaptation via VCDS will likely 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.
