Bosch Me711 Pinout [repack] Access

This is the primary method used by tuners and enthusiasts on NefMoto or S4wiki to perform an "Immo-Off" (immobilizer delete) or to recover a unit that no longer communicates via the diagnostic port. Standard Bench Pinout (Common VAG/Audi)

To understand the importance of the pinout, one must first understand the architecture of the ME7.1. Unlike its predecessors which relied heavily on standalone subsystems, the ME7.1 was an integrated system. It utilized a powerful 32-bit Motorola processor (often the MPC555) to manage air-fuel ratios, ignition timing, and boost pressure simultaneously to achieve optimal torque. This complexity is reflected in its physical form: the ME7.1 typically utilizes a robust connector system with 134 pins (often split into specific sectors). Without a comprehensive pinout diagram, this connector is an impenetrable wall of plastic and metal.

If you are swapping an engine and using a wiring diagram labeled "2001 Audi A4 1.8T" – that is ME7.1.1. Use the pinout above.

Looking at the harness plug (not the ECU), with the locking lever at the top:

The ME7.11 uses a connector (two rows: A & B). This guide covers the most common functions.

Connector B (often black) — pins B1→B28 (examples)
