The SMEG 317AR3 update fixed a genuine embedded software defect that undermined the reliability of an otherwise well-engineered refrigerator. Firmware version v2.0.4 resolves sensor lag, defrost interruption, and post-outage display freezes. Owners experiencing temperature swings or ice buildup should check their unit’s firmware version (press and hold ‘Mode’ + ‘Coldest’ for 5 seconds to display current FW). If below v2.0.4, the update is strongly recommended.
Final verdict: The fix is robust, the update process is straightforward (with a USB tool), and the unit performs as originally advertised. SMEG has quietly restored its reputation for this model – but only after the patch.

The 3.17.A.R3 update was a significant maintenance release for the first-generation 7-inch touchscreen units. It was primarily designed to stabilize the user interface and resolve early bugs reported by owners of the then-new Peugeot 208. Key Fixes and Improvements
The "fixed" aspects of this update primarily addressed functional annoyances and system stability:
Radio Mute Persistence: Fixed an issue where the radio would not stay muted after restarting the vehicle. The SMEG 317AR3 update fixed a genuine embedded
Navigation Search: Improved the satellite navigation to allow for full postcode searches (7 digits in the UK), whereas previous versions often only accepted the first 3 or 4 digits.
Touchscreen Responsiveness: Addressed minor lags and "ghost" inputs on the 7-inch interface.
Bluetooth Connectivity: Improved pairing stability with early smartphone models.
Map Rendering: Resolved occasional "weird colors" or missing icons (like the car cursor) after map updates, though factory resets are still sometimes required for this specific fix. How to Verify Your Version For service documentation or to request a USB
To check if your system is running version 3.17.A.R3 or needs an update:
Access System Info: Hold the "Menu" or "SRC" button (depending on your model) for approximately 5 seconds. View Version: Select "System Version." Identify the Code: 3.xx: Original SMEG system. 5.xx: SMEG+ (Plus) system. 6.xx: SMEG+ iV2 (with MirrorScreen). Update Path
If you are currently on a version lower than 3.17, you can update to this version via a FAT32-formatted USB drive. Note that while 3.17.A.R3 fixed many early issues, later versions like 3.21.A.R1 are considered the final stable releases for this specific hardware generation. Compatibility This firmware is typically compatible with: Peugeot: 208 (2012+), 2008 (2013+). Citroën: DS3, C3, and early C4 models.
