These are the tablet-style units (NACw) found in the facelifted 2008 and the all-new 2008 (P24). Accessing this mode is more cryptic and requires a "Red Button" or "Engineering Button" code.
The Engineering Mode on a Peugeot 2008 is a hidden diagnostic menu within the infotainment system (NAC or RCC units) that allows technicians and advanced users to view real-time system data. While it offers deep insights into your vehicle's software and hardware performance, it should be used with caution, as changing certain settings can lead to system instability. Common Engineering Mode Codes for Peugeot 2008
Accessing the menu requires a specific code based on your vehicle's infotainment hardware:
Code 1111: Primarily used for NAC (Navigation System) units.
Code 7503900: Typically used for RCC (Radio System without built-in Navigation) units.
Code 25041045: Reported for some newer models (circa 2024) to access advanced variant coding. How to Access Engineering Mode
The method for entering these codes varies slightly depending on your Peugeot 2008's generation and unit type:
RCC Systems: Press and hold the Music/Radio button (often marked with a musical note) for approximately 6 seconds. When the keypad appears, enter 7503900.
NAC Systems: Press and hold the Music/Piano key for roughly 5–10 seconds. When prompted for a four-digit code, enter 1111.
Alternative Method: For some touchscreen-only versions, tap the House/Home icon, navigate to the Bluetooth dialer (ensure your phone is disconnected), and enter *#*#888 followed by the call button. Features Available in Engineering Mode
Once inside, you can access several sub-menus designed for troubleshooting:
Spy Mode: Generates system logs (spy lists) that can be exported to a USB drive for error analysis.
HMI Monitor: Provides detailed info on the radio, audio levels, and interface settings.
Connectivity: Displays real-time status for Bluetooth, Wi-Fi, and USB ports, including the ability to toggle USB hub activation.
GPS Positioning: Shows the number of satellites connected and current coordinate accuracy.
System Info: Detailed CPU load, RAM usage, and temperature readings for internal components like the power amplifier and storage. Important Safety Warning

System Risk: Do not change any settings or toggle switches unless you know exactly what they do; incorrect changes can lead to a "black screen" or disable the reverse camera.
Warranty: Accessing these menus typically does not void a warranty, but bricking the system through these menus likely will not be covered for free repair.
Here’s a deep, detailed post aimed at owners, DIYers, and techs researching the Engineering Mode (also called Test Mode or Dealer Mode) on a Peugeot 2008, specifically focusing on how to access it and what the codes/data mean.
Title: Deep Dive: Peugeot 2008 Engineering Mode – Hidden Codes, Live Data & What It Really Tells You
If you’ve stumbled across terms like “Engineering Mode Peugeot 2008 Code” or seen videos of someone holding down the “Mode” button while starting the car, you’re likely after more than just a party trick. You want real vehicle telemetry without a $5,000 diagnostic tool.
Let’s cut through the noise. Here’s exactly how to access the hidden Engineering Mode on your Peugeot 2008 (2013-2019 era, typically with SMEG or SMEG+ head unit) – and more importantly, what those cryptic codes actually mean.
Full read/write access requires DiagBox v9.x with a VCI (Vehicle Communication Interface). This allows:
There is no public code to emulate DiagBox via the touchscreen.
Once inside, you will see a list of technical folders. Here are the most useful ones:
You cannot use Apple CarPlay or Android Auto to bypass the engineering mode. These are sandboxed environments. However, apps like "Car Scanner" (using a Bluetooth OBD2 dongle) will give you more data (engine RPM, coolant temp, turbo boost) than engineering mode will.
