🔌 Note: If you are building a bench harness to flash the ECU, you only need pins 62 (switched 12V), T2/T3 (constant 12V), T1 (ground), and 104 (K-line). The Bosch ME7

The Bosch ME7.1.1 (often shortened to ME711 in casual conversation, though the correct industrial suffix is 7.1.1) is one of the most iconic Engine Control Units (ECUs) from the late 1990s and early 2000s. Found predominantly in Audi, Volkswagen, Seat, and Skoda models with 1.8T 20V engines (codes like AEB, ATW, AWM, and B5), this ECU represents a sweet spot between analog simplicity and early drive-by-wire sophistication.

For tuners diagnosing a no-start condition, wiring a standalone harness, or repinning an ECU for a swap, understanding the Bosch ME711 pinout is non-negotiable.
