Citroën diagnostic tools – precise vehicle diagnostics with Vident iLink400 & iAuto701

Citroën has always stood for a spirit of innovation, unconventional technology, and French automotive charm. Founded in 1919 by André Citroën, the brand is now part of the Stellantis Group. Known for models like the revolutionary DS, the 2CV (Duck), and modern vehicles like the C3 Aircross, Citroën is also a pioneer in electronic vehicle systems. Comfort, creativity, and complex control units characterize the Citroën portfolio. This is precisely why a conventional OBD2 scanner is often insufficient. Anyone wanting to reliably maintain a Citroën vehicle or professionally read fault codes needs a diagnostic tool with deep system integration and brand-specific software – such as the Vident iLink400 or the iAuto701.

At Auto-Diagnostik.de you can get two high-performance diagnostic tools specifically designed for the requirements of modern Citroën vehicles. Whether you run an independent garage or are an ambitious private user – with these tools you can access manufacturer-specific control units, perform complex service routines, and remain flexible even with newer model series.

Why do Citroën vehicles require a specialized diagnostic tool?

Within the PSA Group, Citroën utilizes a complex on-board network system with a central BSI (Body of Servitude Intelligent) control unit. This module handles numerous control and monitoring functions – from automatic headlights to central locking, from sensor queries to communication with other control units. It also incorporates brand-specific features such as the control of automated manual transmissions (ETG), the management of FAP particulate filters and AdBlue systems, as well as the integration of electronic comfort functions.

A universal OBD2 tester typically only covers the engine control unit and provides no useful information on airbags, ABS, ESP, air conditioning, or on-board electronics. Resetting fault codes or relearning components is also not possible with basic devices. Therefore, a more in-depth, brand-specific diagnostic solution is essential for Citroën – both in workshops and for dedicated Citroën drivers.

The Vident iLink400 – targeted Citroën diagnostics at a professional level

The Vident iLink400 is a brand-specific diagnostic tool that comes with unlockable Citroën software. This gives you access to almost all vehicle-specific control units – including comfort modules, safety systems, and emissions-related components.

Functionality for Citroën:

Reading and deleting fault codes in control units
Access to BSI system, airbag, ESP, ABS, transmission, comfort functions
Service reset, resetting the oil change indicator
FAP filter regeneration and ash load reset
AdBlue system check, tank level sensor check
Calibration of sensors and actuators (steering angle sensor, throttle valve, etc.)
Battery Management – Battery adjustment after replacement

The iLink400 is updateable, offers a German-language user interface, and is particularly suitable for users specializing in Citroën or PSA vehicles. Targeted brand integration ensures clear menu navigation and highly efficient diagnostics. The device operates without a PC, is portable, and boasts a robust design.

Advantages of the Vident iLink400 for Citroën:

OEM-level diagnostic depth for virtually all Citroën systems
Brand-specific special functions: FAP, EGR, ETG, AdBlue, BSI

The Vident iAuto701 – a multi-brand solution with direct Citroën support

The Vident iAuto701 is aimed at users who service multiple vehicle brands but still want manufacturer-specific diagnostic depth. Unlike the iLink400, the Citroën software is already pre-installed – without any additional activation or license unlocking. This makes the iAuto701 a ready-to-use solution for Citroën and many other manufacturers.

Typical applications of the iAuto701 at Citroën:

System-wide fault diagnosis in engine, transmission, brake systems, airbag & comfort modules
Real-time data display: sensors, injection parameters, voltage values
Service interval reset including oil service, inspection, brakes
EPB reset, calibration of chassis sensors
BSI access for configuring comfort functions
Particulate filter regeneration and ash condition check

Thanks to its intuitive menu, fast system navigation, and multilingual interface, the iAuto701 is extremely reliable in both everyday workshop use and mobile applications. For independent workshops or Citroën drivers with other brands in their fleet, this device is a highly recommended alternative to the brand-specific iLink400.

BSI – the heart of Citroën diagnostics

The Intelligent Servitude Unit (BSI) is the central gateway for many Citroën control units. It coordinates comfort systems, communicates with the engine control unit, controls the lights, the immobilizer, and many safety-related functions. Only diagnostic tools with direct access to the BSI can change configurations, program new keys, or initialize specific sensors. Both the iLink400 and the iAuto701 have the necessary functions to fully access the BSI module.
