The Peugeot 2008 does not have a secret numeric "engineering code" in the conventional sense. Access is granted via button sequences or touchscreen taps, not a password. The so-called "code" most owners seek is either the anti-theft radio code or a myth perpetuated by aftermarket head unit forums. For genuine diagnostics, use the documented long-press or multi-tap methods described in sections 3.1 and 3.2. For any configuration changes, a dealer-level DiagBox tool is mandatory.
