The Engineering Mode (often mislabeled as a "hidden menu" requiring a secret code) is a factory-installed diagnostic overlay within the Peugeot 2008’s infotainment system (SMEG, NAC, or RCC head units). Contrary to popular belief, there is no universal "unlock code" for full engineering access. Instead, this paper documents the standard diagnostic procedures, the software version access codes, and the specific sequences required to view critical vehicle data (e.g., battery voltage, GPS coordinates, radio signal strength, and firmware versions).
The Engineering Mode on a Peugeot 2008 is a read-only window into your car’s electronic soul. It won’t give you a magic “code” to unlock horsepower or disable stop-start, but it will help you catch a failing battery, spot odometer fraud, or confirm a CAN bus glitch before your mechanic charges you an hour’s labor.

The term "Engineering Mode" in the context of the Peugeot 2008 (typically the first generation K0 and the second generation P24) usually refers to accessing the hidden diagnostic menus within the infotainment system (SMEG/NAC/RCC units) and the instrument cluster. These hidden menus allow for hardware testing, system configuration, and error checking that are not available to the standard driver.
Disclaimer: This guide is for educational purposes. Accessing engineering menus and altering settings can cause system instability or void warranties. Proceed at your own risk.
Accessing Engineering Mode (also known as the "Hidden" or "Spy" menu) on a Peugeot 2008
allows you to view system logs, check GPS signal strength, and verify software versions. The method for entering this mode depends on whether your vehicle uses the older SMEG system or the newer NAC/RCC infotainment platforms found in second-generation models (2019–2025). Accessing Engineering Mode (NAC & RCC Systems)
For modern Peugeot 2008 models, follow these steps to trigger the hidden menu:
Press and Hold the Music Button: Locate the "piano key" button with the musical note icon and hold it down for approximately 4 to 6 seconds.
Enter the Access Code: A prompt will appear asking for a four-digit code.
Common Code: 1111 is the standard code used to access "Spy Mode".
Alternative Method (Screen Taps): If the button hold does not work, some systems require specific screen interactions: Tap the House icon (home).
Go to the Bluetooth dialer screen and enter *#*#888 followed by the green call button. Select Guest Login to enter the diagnostic pages. Accessing the Service Menu (SMEG Systems) For older models with the SMEG navigation system: Turn the ignition on and wait for the system to boot.
Press and hold the MENU button for several seconds until the service menu appears.
This menu typically includes detailed software and map version information. Critical Safety Warning
Do Not Modify Settings: Engineering Mode is intended for diagnostic purposes. Changing values without expert knowledge can lead to system instability or "bricking" the infotainment unit.
Document Before Changing: If you must adjust a setting, take a photo of the original configuration first so you can revert if necessary.
System Reboot: If the system becomes unresponsive, you can usually perform a soft reboot by holding the power button for 10 seconds. Hidden Menu - Peugeot Forums
Accessing the Engineering Mode on a Peugeot 2008 (typically for models equipped with the NAC or RCC infotainment systems) involves a specific physical trigger followed by a numeric passcode. This mode is primarily used by technicians to view system diagnostics, GPS data, and firmware versions. How to Access Engineering Mode
