The ME7.4.5 communicates via high-speed CAN for diagnostics and flashing. Grey Connector -> Pin B3 CAN Low: Grey Connector -> Pin A3 4. K-Line (For older tools) K-Line: Grey Connector -> Pin C1 Boot Mode & Flashing Tips
If you're trying to read the full internal flash (ST10F275), remember that this ECU usually requires adding two 6k8 resistors and removing one resistor on the board to trigger the bootstrap. Always verify your board version before soldering! me7.4.5 pinout
This report details the pinout configuration of the Bosch ME7.4.5 Engine Control Unit (ECU). This ECU is a prominent Motronic system utilized primarily by PSA Peugeot Citroën and Renault for 1.4L, 1.6L, and 2.0L gasoline engines (specifically the TU5, EW10, and F4P/R engine families). Understanding the pinout is essential for engine conversion specialists, diagnostics technicians, and ECU tuning professionals. The ME7
Note: "ME7.4.5" refers to a Bosch Motronic engine control unit family used on various Volkswagen Group gasoline engines (commonly found in VW/Audi 1.8T, 2.0, etc.). Pinouts can vary by vehicle model, connector type, and hardware revision. Below is a concise, commonly encountered ME7.4.5 pin mapping for the 60‑pin (or 55/60) rectangular main harness connector used on many 1.8T installations. Treat this as a general reference; confirm against your vehicle’s service manual or measured signals before wiring or diagnosing. Always verify your board version before soldering
: One specific resistor on the ECU board must be removed to enable the mode. Professional Tools
Below is the definitive pinout for the ME7.4.5. Pins are numbered 1 through 121. Pins marked “---” are unused in most manual-transmission 1.8T applications.
