Save an untouched backup of the original bin file before modifying any timing, fuel, or immobiliser parameters.
operates inside a durable aluminum casing engineered to survive severe under-hood environments. To accurately identify pins, hold the module with the .
If you mistakenly use a 32A pinout on a 33A, you will likely ground critical outputs (e.g., swapping A8 with A4). Always verify the label on the ECU case: “Continental Simos 33A.6”.

Safely writing modification files, adjusting pedal response maps, or managing emission systems. The Simos 3.3A Core Bench Pinout Specification
: Standard connection to the ECU case or designated ground pins.
For the Siemens (often labeled with part number 06A 906 033 A ) found in VAG vehicles like the Audi A3 1.6i, the "top" or bench pinout is primarily used for reading pincodes, IMMO OFF procedures, or cloning. Simos 3.3A Bench Pinout Save an untouched backup of the original bin
The SIMOS 33A is most commonly found in and 1.8L TSI engines (EA211 engine family).
Here is a general representation of the Simos 33A pinout top view:
The physical ECU unit typically carries part numbers like 06A906033 or 06A906033xx and the internal hardware is often identified by a starting with 5WP4xxxx , such as 5WP40019 05 or 5WP40019 07 . This makes it a close relative of the SIMOS 3PC and other SIMOS 3.3 variants that share much of the same core architecture and pinout philosophy. If you mistakenly use a 32A pinout on
Highly documented in tuning communities like ECU Connections , making it easy to troubleshoot or modify.
Typically mapped to massive chassis ground pins or specific smaller pins on the primary connector block (e.g., Pin 1 or Pin 2 depending on the exact layout version).
Physically, the ECU is divided into distinct connector sections (plugs), usually referred to as Plug A, Plug B, Plug C, and Plug D.
