When owners discuss "Engineering Mode" on a Peugeot 2008, they are usually referring to one of two distinct interfaces:
| Generation | Model Years | Head Unit | Most Likely Code |
| :--- | :--- | :--- | :--- |
| First Gen (Phase 1) | 2013 – 2016 | SMEG | *#*#3347#*#* |
| First Gen (Phase 2) | 2017 – 2019 | SMEG+ | 3347 (via preset buttons) |
| Second Gen (Phase 1) | 2020 – 2023 | NAC Wave 3/4 | *#*#32277#*#* |
| Second Gen (Facelift) | 2024 – Present | NAC Wave 5 (i-Cockpit) | Dynamic / Dealer only |
Once you successfully bypass the engineering mode code, you will see a wall of data. Here is what the most critical lines mean for your Peugeot 2008. Engineering Mode Peugeot 2008 Code
This is the most commonly used section.
| Goal | Example Sequence (varies by model) |
|------|-------------------------------------|
| Access BSI Engineering Mode | Hold Mode + End call buttons, then press Start twice without brake |
| Reset service indicator manually | Ignition off → Hold trip reset → Turn ignition on → Wait 10s → Release |
| Enable DPF regeneration via Diagbox | Security code: 03114 (for certain BlueHDi ECUs) |
| Deactivate auto stop-start permanently | Engineering menu → BSI → Comfort → SSI option → Set to "Not present" | When owners discuss "Engineering Mode" on a Peugeot
Note: Real engineering mode entry often requires a professional scan tool (Diagbox v7 or v9) and a 5‑digit alpha‑numeric code generated by the PSA server after VIN authentication.
You will find countless forum threads and YouTube videos asking for the Peugeot 2008 engineering mode code. This is because the system is password-protected to prevent accidental changes. Unlike older Peugeot models (like the 207 or 308) that used simple codes like *#1234# or *#*#3347#*#*, the new Peugeot 2008 (2020–present) has a dynamic or model-specific code. | Generation | Model Years | Head Unit
Crucial Note: There is no single universal code that works on every Peugeot 2008. The code depends on the head unit's hardware version and software release. However, after years of community research and dealership leaks, several standard codes have been identified.
Once inside, you’ll see several screens. The most useful is “Vehicle Data” or “Display Check.” Here are the codes and values you’ll encounter, decoded:
| Code/Field | What It Really Means | Typical Healthy Value | |---|---|---| | VIN | Vehicle Identification Number | Matches your registration | | RTC | Real-Time Clock (battery-backed) | Correct UTC time | | ODO | Odometer (stored in BSI & ECU) | Should match dash | | Distance since reset | Trip computer memory | Varies | | ECU ID | Engine control unit software version | Alphanumeric code | | BSI | Built-in Systems Interface (body computer) | Version & checksum | | Audio Codec Temp | Internal temperature of radio module | 25–55°C | | Battery Voltage (raw) | Voltage at head unit (≈ alternator/battery) | 12.2V (off) / 14.4V (running) | | GPS Fix (if equipped) | Number of satellites locked | 4+ for accuracy | | CAN Bus errors | Lost messages between ECUs | Should be 0 or very low (<5) |
Follow this sequence precisely. Interrupting the boot cycle may lock the system temporarily.
