Bosch Me20 Pinout Verified Page

Before pinning the module, verify your hardware number on the ECU casing (e.g., Bosch part numbers starting with 0 261 20X XXX or Mercedes numbers like A 02X 545 XX XX ). The layout typically separates heavy-duty power and ground feeds from sensitive sensor inputs and data communication lines. Verified Pinout Data

Primary engine sensors (crank, cam, knock).

Bosch ME 2.0 Engine Control Unit (ECU) is a standard fuel injection and ignition system found primarily in Mercedes-Benz Before pinning the module, verify your hardware number

often require specific cables (e.g., F32GN037C) and "boot mode" connections for direct processor access. Troubleshooting and Repairs

The Stack Exchange result (result 0) provides a pinout from Bosch, which is crucial for the "verified" aspect. I'll cite that source. I also have some information about ME2.0 and ME2.1 from the BenzWorld thread, including diagnostic pinouts and flashing procedures. I also have information about pedal value sensors and EVAP purge systems from 124performance.com. I can also include safety precautions.
