4F5LCD is an open-source printed circuit board by Code99it, from the Code99it/4F5LCD repository on GitHub. It is a 2-layer board of 155 × 78 mm with 88 parts on 134 nets, routed with 702 tracks and 76 vias.
It is built around the SN65HVD230D, MCP2515-I and MBRS340, with the SMAJ33A among its other parts. Its parts include 45 capacitors, 22 ICs, 10 crystals, 3 connectors and 2 diodes. It belongs with the ESP32 boards of this library.
Dieses Projekt ersetzt bei Fahrzeugen der VAG-Gruppe mit Plattform 4F (C6) das kleine Display in der Mitte des Kombiinstruments durch eine spezielle Mikrocontroller-Lösung. Die Bedienung erfolgt über die linken Tasten am Lenkrad:
This project replaces the small display in the center of the instrument cluster with a custom microcontroller solution for vehicles of the VAG group using platform 4F (C6). Operation is via the left steering wheel controls:
Dieses System greift ausschließlich lesend auf die fahrzeuginternen Bussysteme (z. B. CAN-Bus) zu.
Es werden nur Statusinformationen wie Temperatur, Drehzahl oder Komfortdaten erfasst.
Kein Zugriff auf sicherheitskritische Systeme (Bremsen, Airbags, ESP, ABS, Antrieb).
Eine Beeinflussung, Veränderung oder Steuerung dieser Systeme ist weder vorgesehen noch implementiert.
No access to safety-critical systems (brakes, airbags, ESP, ABS, drivetrain).
Only status information such as temperature, RPM or comfort data is collected.
This system uses read-only access to the vehicle’s internal bus systems (e.g. CAN bus).
Any manipulation, alteration or control of these systems is neither intended nor implemented.
Für Menüauswahl und Displayanzeige wird schreibender Zugriff auf nicht sicherheitsrelevante Steuergeräte verwendet.
Dieser Zugriff ist funktional begrenzt und beeinflusst weder Fahrverhalten noch Fahrsicherheit.
Write access to non-safety-critical control units is used for menu selection and display output.
This access is functionally limited and does not affect driving behavior or safety.
Sniffing im Rahmen des gesetzlich zulässigen Reverse Engineering (§ 69e UrhG) zur Interoperabilität.
Es wird keine Original-Software extrahiert, kopiert oder verändert – nur das Datenverhalten dokumentiert.
Sniffing under the legally permitted reverse engineering (§ 69e UrhG) for interoperability.
No original software is extracted, copied, or modified – only data behavior is documented.
Du nutzt das System ausschließlich zu Test-, Entwicklungs- oder Forschungszwecken.
Dauerbetrieb im öffentlichen Straßenverkehr erfordert Einzelabnahme (§ 21 StVZO) bei TÜV/DEKRA etc.
Use exclusively for testing, development, or research purposes.
Permanent use on public roads requires single-vehicle approval (§ 21 StVZO) from TÜV/DEKRA, etc.
Nicht autorisiert, geprüft oder freigegeben durch einen Fahrzeughersteller; keine offizielle Verbindung zu Herstellern der VAG-Gruppe.
Jegliche Nutzung erfolgt auf eigene Verantwortung.
Not authorized, tested, or approved by any vehicle manufacturer; no official affiliation with any brand of the VAG group.
Any use is at your own risk.

The 84 most common of 88 parts.
It measures 155 × 78 mm and has 2 copper layers, 1.6 mm thick.
88 parts, built around the SN65HVD230D, MCP2515-I, MBRS340 and SMAJ33A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Code99it/4F5LCD repository on GitHub, at the commit this page was made from: the board is PCB printed circuit board/KiCad/4F5LCD.kicad_pcb and its schematic PCB printed circuit board/KiCad/100powersupply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Code99it before reusing the design.
