The exact list of vehicles equipped with a Security Gateway changes over time. Manufacturers extend protection to new platforms, diagnostic tools gradually add support, and some models may differ by market, model year or specific equipment. Even so, there are vehicle groups where the workshop should expect SGW/SFD in advance.
The following overview is based on DevCom’s long-term experience and serves as an indicative aid. Before a specific service operation, it is always advisable to verify current support in the diagnostic tool and on the DevCom portal.
Stellantis / FCA
The Security Gateway is implemented in a number of FCA/Stellantis brands from the late 2010s. It typically concerns brands such as Abarth, Alfa Romeo, Chrysler, Dodge, Fiat, Jeep, Lancia, Maserati, RAM and Vauxhall. For Peugeot, Citroën and Opel, DevCom’s material highlights selected light commercial models such as Boxer, Jumper and Movano.
On these vehicles, the workshop should expect that some special functions, actuator tests or, in some cases, fault memory clearing may not be available without authorised access.

Volkswagen Group: MQB Evo / MQB2020 and MEB
In the Volkswagen Group, SFD protection typically concerns vehicles based on MQB Evo / MQB2020 and MEB platforms. Examples include Audi A3 8Y, SEAT León KL, Škoda Octavia IV, Škoda Scala, Škoda Kamiq, Volkswagen Golf 8, Volkswagen Caddy, Cupra Formentor and Volkswagen Multivan.
For electric vehicles on the MEB platform, overviews include, for example, Audi Q4 e-tron, Cupra Born, Škoda Enyaq, Volkswagen ID.3, ID.4, ID.5, ID.6 and ID. Buzz. On these vehicles, the workshop should expect protection of advanced diagnostic functions, especially coding, adaptations, basic settings and other interventions in ECU configuration.

Mercedes-Benz
For Mercedes-Benz implementation comes since 2020, first used in the S-Class generation W223. Affected models include, for example, C 206, E 214, EQE, EQS, CLE, S 223, SL 232, AMG GT 192 and GLC 254.
On newer vehicles, diagnostic access may be restricted more strictly than only for a particular service function. The workshop should therefore verify in advance that it has the correct access and supported diagnostics available.

Hyundai, KIA and Genesis
SGW appears in some Hyundai/KIA models as early as 2018. For KIA, examples include Ceed, EV6, K5, Sorento, Sportage, Stinger, Telluride and Xceed. For Hyundai, overviews include Elantra, i20, Ioniq 5, Nexo, Palisade, Santa Fe, Staria, Tucson and Venue. For Genesis, examples include G70, G80, G90, GV70 and GV80.
Again, the list is indicative. For a specific vehicle, the model year, equipment and electronic architecture are decisive. If the workshop is preparing for a special function or actuator test, it is better to expect possible SGW protection and verify access in advance through DevCom Diagnostic portal, or via technical support.

How to use this article in practice
- as a supporting link from articles about SGW and SFD
- as an indicative aid for customers trying to understand why an advanced function cannot be started
- as a basis for a future updated page with supported brands and models
- as material for sales communication relating to TSPro and Troodon diagnostics
The main message is simple: SGW/SFD is not an exception, but a new standard. Workshops that want to work professionally with modern vehicles need diagnostics that can not only communicate with control units, but also correctly handle authorised access from vehicle manufacturers.
