The ME7.1.1 ECU has multiple different printed circuit board (PCB) revisions. Therefore, the physical point where you short Pin 24 can vary. On some boards, there are dedicated solder pads. On others, you must connect directly to the leg of the flash chip itself. Always double-check your specific ECU's board layout before attempting this.

NefMoto and other standard K-Line flashers often fail if the baud rate is set too high on generic FTDI cables. Lower the latency timer to 1ms in your Windows Device Manager settings and force a slower speed (e.g., 38400 or 57600 baud) in your software. bosch me711 pinout
The ME711 is a hybrid of two diagnostic eras. It features a on Pin 43 (Connector C), which is the classic slow communication used by VAG-COM (VCDS) to read fault codes and measuring blocks. Simultaneously, it supports early CAN-Bus (High on Pin 51, Low on Pin 52) for communication with the ABS module and instrument cluster.
Hold the ground on Pin 24, turn on the +12V ignition power (Pin 21), wait 3 seconds, and then remove the ground probe from Pin 24. The ME7

Note: While some ME7.1.1 variants support high-speed CAN flashing, the K-Line (Pin 43) remains the most reliable and universally supported method for bench flashing. Bootmode Pinout: Recovering a Bricked ECU On others, you must connect directly to the
The following pin assignments are standard for basic bench connections, allowing for communication with the ECU without needing the full vehicle harness. Connection Type Pin Number(s) Description Terminal 31 Main Ground Permanent Power (+12V) Terminal 30 Constant Battery Power Ignition Power (+12V) Terminal 15 Switched Ignition K-Line Diagnostic communication line CAN High High-speed CAN bus signal CAN Low High-speed CAN bus signal
When upgrading from ME7.1 to ME7.1.1, you may need to reorganize the pins, often described as "repinning" to ensure power and ground are in the correct slots.
