Bosch ME7.4.5 is a common Engine Control Unit (ECU) used primarily in Peugeot and Citroën (PSA) vehicles with the 1.6 16v (TU5JP4) engine

. Accessing its pinout is essential for bench diagnostics, ECU cloning, or recovery via boot mode Essential Bench Connection Pinout

For a standard bench connection (diagnostics and standard reading), the following pins on the

middle connector (often referred to as Connector B or the 48-way connector) small connector (Plug C) are typically used +12V Power Supply (K30): Ignition (+12V):

(Sometimes also pins F2 and G2 depending on the specific hardware version Ground (Masse/GND): K-Line (Communication):

Note: For direct connection using universal cables like F32GN037C, some manuals specify power should be connected to POL4 and POL5 pins Boot Mode Pinout (ECU Recovery)

If the ECU is unresponsive ("bricked"), you must put it into to flash the internal memory directly

Here is the pinout for the ME7.4.5 (Bosch Motronic ME7.4.5), commonly found in early 2000s VW/Audi 1.8T (20v) engines, as well as some SEAT, Škoda, and certain BMW models.

ECU Connectors:
The ME7.4.5 uses three main connectors: T121 (engine harness), T94 (vehicle harness), and T80 (secondary functions). The most referenced for tuning/repair is T121 (121-pin). me7.4.5 pinout
