How to deactivate the seatbelt warning chime on Skoda Octavia 4 (NX) Iamcarhacker

By Juraj · Last updated: May 2, 2026

This guide shows how to silence the seatbelt warning chime and the corresponding warning icon in the Virtual Cockpit on a Skoda Octavia 4 (NX, 2020+). After coding, the car no longer beeps or flashes the icon when you’re driving without a fastened seatbelt — a single adaptation in module 17 (Instruments) flips it off.

Video: How to turn off the seatbelt warning chime on Skoda Octavia 4 NX (OBDeleven one-click app)

The video walks through doing this with OBDeleven’s one-click app. The 7 manual steps below are what’s happening underneath if you’d rather do it through the adaptation menu in OBDeleven Pro or VCDS.

Technical overview

Item	Details
Vehicle	Skoda Octavia 4
Year	2020
System	17 – Instruments (digital cockpit / Virtual Cockpit)
Procedure type	Adaptation (single channel, multiple variants)
Difficulty	Easy
Time required	~5 minutes
Prerequisites	OBDeleven Pro/Ultimate or VCDS, SFD unlock, ignition ON,

Step-by-step procedure

Engine off, ignition off. Plug your OBDeleven dongle (or VCDS cable) into the OBD2 port under the dashboard on the driver’s side.
Switch the ignition on and open OBDeleven or VCDS.
Select control module 17 – Instruments.
Open Adaptation – 10.
Unlock SFD protection. In OBDeleven this is under the SFD menu and requires you to be signed into your account; in VCDS it’s the SFD flow under “Security Access”.
From the top dropdown, select the channel Deactivate_belt_warning.
From the bottom dropdown, select Yes and validate.

That’s it. Cycle the ignition off → wait a few seconds → on. The next time you drive, no chime, no flashing belt icon.

If you change your mind, repeat steps 1–6 and select No in step 7.

Additional Information & Compatibility Notes

Before using or purchasing any diagnostic tool for this procedure, always verify compatibility with your exact vehicle model, year and system configuration. Supported functions may vary depending on software version, hardware revision and regional limitations.

A few things specific to this procedure:

Disables the warning for the driver and front passenger seats. Once written, neither position will trigger the chime or the icon. Rear seat belt monitoring on this platform is purely informational (no chime), so it isn’t affected.
The seatbelt itself still works. This is purely a UI change — pretensioners, airbag interaction with seatbelt status, and crash data recording all continue to function normally. You’re only suppressing the warning, not the safety system.
Reversible. Set Deactivate_belt_warning back to No to bring the chime back. No fault codes generated either way.
SFD unlock is per-session. Each time you reconnect to write to module 17 you’ll need to unlock SFD again. Reading channels works without it.
Legal & inspection considerations. In the EU, an active seatbelt warning is part of the vehicle’s type approval (UN/ECE R16). Disabling it can be flagged at periodic technical inspection (STK / TÜV / MOT depending on country) and may also affect insurance in the event of a claim. Check your local rules before deciding whether to apply this — in some countries this exact change is grounds for failing inspection. The coding is reversible, so a common workflow is to switch it off for daily use and reverse it before inspection.
