Engine Control Unit Volkswagen Siemens Simos 10.12 03F906070J 5WP44744

Simos is a family of Siemens (later Continental) ECUs for petrol engines. This Simos 10.12 unit has VW number 03F906070J and manufacturer number 5WP44744 in the Siemens VDO numbering system. It controls fuel injection, ignition and the throttle. Our data does not include a specific Volkswagen model, so we base matching solely on the numbers.

Numbers on the label

  • 03F906070J – Volkswagen part number
  • 5WP44744 – Siemens manufacturer number
  • Simos 10.12 – ECU family

The letter J at the end of the VW number denotes the software or hardware version. A 03F906070 unit with a different letter may contain different data, so compare both numbers in full before buying.

Symptoms of a possible fault

  • no start with a working fuel and power supply,
  • engine warning light on and loss of power,
  • rough running, misfires with no coil fault,
  • the ECU does not respond to the diagnostic tool.

Start by checking the earths, fuses and connector condition – some of these faults originate in the wiring rather than in the unit itself.

  • Where to buy a used automatic transmission control unit? Complete guide

    The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.
