If bench reading fails, some variants require grounding specific pads on the PCB (BSL mode) to enable programming. Always "probe" or verify continuity to the processor pins before applying voltage to unknown pads.

For the most reliable and current information, consider joining specialized forums like MHH Auto or Cartechnology.co.uk and posting a specific request for your ECU's part number (e.g., 06A906033BD). The community is often willing to share detailed pinouts, especially for bench reading or immobilizer bypass procedures.

Some variations may use Pin 43 specifically for the K-Line diagnostic signal required for reading the EEPROM or flash memory on the bench. Professional Bench Tools Can’t copy the link right now
