Open the Hidden Diagnostic Menu

Last updated: June 12, 2026

The Peugeot 2008 (Mk2/P24, 2019–present) shares its i-Cockpit dashboard and Stellantis IVI touchscreen with the 208 of the same era, and that head unit hides a genuine Engineering Mode you can open yourself — just your fingers and a code, no Diagbox and no garage. It is a service screen that reveals the infotainment’s software versions and crash logs. This guide covers the touchscreen 2008 Mk2, including the all-electric e-2008.

What Engineering Mode shows

This is the IVI system’s built-in technician page, so expect plain text rather than the usual graphics. On the 2008 Mk2 it typically exposes:

• System / version information — the IVI software build and the radio (BSRF) module version, so you can tell whether a dealer update applies to your car.
• Logging — the spy logs the screen records whenever an app inside it crashes or hangs.

It is read-only in practice. Unlike a dealer’s Diagbox session, this owner mode will not recode features or change vehicle options — you can look at versions and pull logs, and that is all.

How to open it

Do this parked, with the ignition on and the touchscreen fully booted to the normal home display.

1. Place three fingers flat on the touchscreen together.
2. Press and hold all three for at least four seconds until a numeric keypad appears.
3. Enter the code 1232020 and press the tick / confirm button.
4. Engineering Mode opens with the System and Logging options.

The three fingertips need to touch the glass at the same moment — if a normal menu reacts instead, lift off and try again with a cleaner simultaneous press.

Reading it

Use System to read the IVI and radio versions before asking a dealer whether your 2008 is on the latest software. Open Logging if the display has been freezing or restarting by itself — fresh spy logs confirm a genuine software fault you can raise at the service desk, rather than a stray one-off.

How to exit

Tap the back or home control to leave, or cycle the ignition off and on. The IVI always reboots into the normal owner interface, and nothing you viewed is changed or stored.

Frequently Asked Questions

Is the procedure the same as the Peugeot 208?

Yes. The 2008 Mk2 uses the same IVI head unit as the 208 Mk2, so the three-finger hold and code 1232020 open the identical Engineering Mode. If you know the 208 method, it transfers directly.

Does it work on the electric e-2008?

It does. The e-2008 runs the same IVI infotainment, so the gesture and code are unchanged. The pages cover the screen’s own software, not the drive battery.

Can I unlock hidden equipment from this menu?

No. The owner-accessible Engineering Mode only reads versions and transfers spy logs. Activating extra features still needs a dealer tool such as Diagbox — that capability is not exposed here, which is why the mode is safe to enter.

The keypad will not appear — what am I doing wrong?

Let the screen finish booting first, then press with three fingertips touching at once and hold for a full four to five seconds. A glancing or one-finger-late touch is read as ordinary taps and the keypad will not come up.

Will this show battery voltage or temperatures?

The 2008 Mk2’s IVI Engineering Mode is built around software versions and logs, not live electrical read-outs. To check the 12V battery, measure it at the terminals with a multimeter rather than relying on this screen.

If a warning light or fault message is showing on the dash alongside any screen trouble, your 2008 may have stored a diagnostic trouble code — you can look up what it means on autodtcs.com.
