Bosch Me711 Pinout [better] Guide

Bosch ME7.1.1

Finding a complete, accurate pinout for the ECU—commonly found in VAG (Volkswagen Audi Group) and some Porsche vehicles—is essential for bench flashing, boot mode operations, or diagnostics. Bosch ME7.1.1 Bench Pinout (Standard VAG)

| Feature | ME7.1 (rare) | ME7.1.1 (common) | |-------------------------|-------------------|----------------------| | Injector pins | 85-88 only | 82-85 | | Extra 5V sensor supply | No | Yes (pin 60) | | Secondary O2 sensor | Not pinned | Pin 100 | | Electronic throttle | Sometimes cable | Always drive-by-wire | bosch me711 pinout

| Pin Number | Pin Name | Description | | --- | --- | --- | | 50 | CAN_H | CAN bus high | | 51 | CAN_L | CAN bus low | | 55 | K-Line | Diagnostic interface | Bosch ME7

• Processor: Infineon C167CR (similar to ME7.5 but with less internal flash)
• Memory: External 29F800 flash chip (requires boot mode for flashing)
• Sensors: Uses a MAP sensor (Manifold Absolute Pressure) rather than a MAF? No—ME711 typically retains a Hot-Film MAF. However, it lacks some of the torque model complexity of ME7.
• Actuators: Controls electronic throttle (E-Gas), ignition coils with integrated drivers, and injectors (high impedance).
• Common Vehicles:

  Conclusion

  Physical Identification

  pins 27, 28, and 29

  The ME711 requires constant voltage on (Terminal 30). Without these, the ECU is dead. Ground integrity on pins 43, 44, 45, and 121 is critical. A common failure is a corroded engine-to-chassis ground strap, causing erratic sensor readings (especially TPS and MAP). Processor: Infineon C167CR (similar to ME7
