This guide provides the instructions and common codes needed to access the Engineering Mode (also known as the Hidden Menu) on the Peugeot 2008.
This menu allows you to view diagnostic data, battery voltage, temperature, radio signal strength, and screen sensor data. It is useful for troubleshooting issues or checking system health without a mechanic.
Manufacturers vary across model years and infotainment versions. A commonly reported method (for research/diagnostic use only) is:
Note: Exact button combinations differ by model year and head-unit firmware. If you need the exact code/sequence for a specific year and head-unit version, provide the model year and infotainment firmware version.
Engineering Mode (also called Service Mode or Diagnostic Mode) is a hidden manufacturer menu on the Peugeot 2008 infotainment/comfort system that grants access to system information, software versions, certain diagnostic screens, sensor values, and calibration/settings not normally exposed to users.
The user is guided to provide:
"The pop-up won't appear!"
"None of the codes work!"
If the common codes fail, your specific VIN may be tied to a specific dealer code. In this case, specialized software (like Diagbox) is required to extract the specific engineering code for your unit. However, 0514 works for the vast majority of Peugeot 2008 Mk1 models.
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.
