| = Volkswagen SFD, SFD2 & Service Reminder Reset (SRI) with VCDS =
| |
| | |
| == Overview ==
| |
| | |
| Volkswagen Group introduced SFD ('''Schutz der Fahrzeugdiagnose''' – Protection of Vehicle Diagnostics) in 2020 to enhance cybersecurity and control access to vehicle software. In 2024, a second layer called '''SFD2''' was introduced, requiring cryptographic validation for critical changes.
| |
| | |
| This page explains how VCDS interacts with SFD and SFD2 systems and provides step-by-step instructions for resetting the Service Reminder (SRI) on protected vehicles.
| |
| | |
| == What is SFD and SFD2? == | |
| | |
| '''SFD (v1)''' restricts coding, adaptations, and other “write” functions unless a one-time unlock token is used. VCDS supports this system using a manual token entry method.
| |
| | |
| '''SFD2 (v2)''' is used in 2024+ vehicles and protects specific data changes using encrypted, per-operation validation. SFD2 requires Volkswagen’s online infrastructure and is currently unsupported by VCDS.
| |
| | |
| SFD and SFD2 do '''not''' block:
| |
| * Reading fault codes (DTCs) | |
| * Viewing live data (Measuring Blocks)
| |
| * Performing an Auto-Scan
| |
| | |
| == How VCDS Works with SFD ==
| |
| | |
| VCDS supports SFD by:
| |
| * Detecting SFD-protected modules
| |
| * Displaying the module's challenge string
| |
| * Allowing manual entry of the corresponding unlock token
| |
| | |
| VCDS does not generate or request unlock tokens itself. Tokens must be obtained separately and are valid for:
| |
| * One module only
| |
| * One session (approximately 90 minutes)
| |
| | |
| '''SFD2 is not supported by VCDS.'''
| |
| | |
| == Manual Unlock Process in VCDS ==
| |
| | |
| # Open VCDS and connect to the module
| |
| # Attempt a function (e.g., Adaptation or Security Access)
| |
| # Copy the displayed challenge string
| |
| # Submit the challenge to a trusted token provider
| |
| # Paste the returned release token into VCDS
| |
| # The module unlocks for ~90 minutes
| |
| | |
| == Resetting the Service Reminder (SRI) ==
| |
| | |
| === Vehicles Without SFD (Pre-2020) ===
| |
| | |
| Older vehicles do not require SFD unlocks.
| |
| → [https://www.ross-tech.com/vcds/tour/sri-reset.php SRI Reset Tour Page]
| |
| | |
| === Vehicles With SFD ===
| |
| | |
| Some newer vehicles (e.g., Golf 8, ID.4) have SFD in:
| |
| * '''17-Instruments''' | |
| * '''5F-Infotainment'''
| |
| | |
| Steps:
| |
| # Retrieve the challenge string in VCDS
| |
| # Obtain and enter the unlock token
| |
| # Perform the SRI reset within the 90-minute window
| |
| | |
| === Vehicles With SFD2 / Gateway Filtering ===
| |
| | |
| Newer platforms may also use a diagnostic filter in '''19-Gateway'''.
| |
| | |
| Steps:
| |
| # Retrieve and unlock 19 using a token
| |
| # In 19, go to Adaptation and set:
| |
| <code>DE16611 – Diagnosis filter: temporary deactivation → not active</code>
| |
| # This disables the diagnostic filter for ~20 km
| |
| # Unlock 5F (or other protected modules) using tokens
| |
| # Perform the SRI reset
| |
| | |
| <span style="color:orange;"><b>Tip:</b> While in R-Mode, you can collect challenge strings for both 19 and 5F and request both tokens at once.</span>
