Siemens SID804 Immo off solution for PSA models
The Siemens SID 804 ECU is used in a variety of PSA group diesel vehicles, primarily in mid-2000s, such as Peugeot 1007 and Citroën C3 with 1.4 HDi engine. This ECU is known for its compatibility with advanced immobilizer systems that, while secure, can present challenges during ECU replacements or key issues. Our solution offers a precise method to disable the immobilizer function without interfering with the ECU’s core operation.
This immo off solution is ideal for scenarios where key loss, immobilizer faults, or ECU cloning makes bypassing the immobilizer essential. Unlike immo virgin procedures—which reset the ECU for reprogramming—our immo off disables the immobilizer logic entirely, allowing the engine to start independently of the original key signal.
