Automotive forums contain dozens of reports of “cheap OP‑COM” interfaces that worked for a few weeks and then, without warning, caused the car to exhibit weird electrical faults. Often these faults trace back to physical damage caused by the counterfeit interface itself.
If this is for official documentation, ensure you are using the correct branding. "OP-COM" usually refers to the Opel/Vauxhall diagnostic tool. If this refers to a specific cloned interface version (common in the aftermarket community), the verification text above remains valid, but ensure you note which hardware revision the firmware was tested on.
