Bored Systems: VW & Audi Open Source Development

BoredSystems.com is an automotive development platform focused on Volkswagen and Audi technology. Built by a VW/Audi Certified Technician (Electrical Diagnostics, Networking, High Voltage Expert), Bored Systems develops open-source software and tools for diagnostics, and vehicle networking.

Primary focus areas include:

  • Haldex AWD control systems
  • CAN bus analysis
  • VW/Audi SSP documentation
  • Embedded firmware development
  • Vehicle networking and electrical diagnostics

OpenHaldex SS: Haldex AWD Control for VW & Audi

OpenHaldex SS v1.1 is the current Bored Systems AWD application, powered by SignalScope. It supports conventional Haldex Gen 1, 2, 4 and 5 Volkswagen Group vehicles.

  • Editable AWD maps with live tracing
  • Automatic behavior profiles built from vehicle signals
  • Supported diagnostics, calibration and CAN logging
  • Configuration backup and restore

A LILYGO T-2CAN N16R8 and factory-style connector pair make a reversible inline build, usually about $50 in parts. Check the AWD system first: Mk8 Golf R and 8Y RS3 torque-splitter differentials are not currently supported.

The SS application is proprietary, with free official firmware for personal, non-commercial experimental or off-road use. Legacy MIT-licensed S3 resources remain available.

SSP Search Engine: VW & Audi Factory Documentation

The SSP Search Engine is a searchable archive of Volkswagen and Audi Self-Study Program (SSP) documentation.

This tool allows enthusiasts, technicians, and developers to explore factory documentation covering:

  • Vehicle networking architecture
  • Engine management systems
  • Transmissions and drivetrain
  • Infotainment systems
  • Chassis electronics
  • High-voltage systems
  • CAN bus communication

Designed for the DIY and VAG community, SSP Search centralizes factory-level technical knowledge into a structured searchable interface.

CAN Frame Library (Coming Soon)

The upcoming CAN Frame Library is designed for VAG/PQ/MQB development and reverse engineering.

Planned features include:

  • Searchable CAN frame logs
  • Filter by year, make, model, and platform
  • Frame ID indexing
  • Signal visualization tools
  • Time-based CAN log graphing

Future integration with OpenHaldex may allow optional community-driven CAN data contribution.

SignalScope: API Runtime + S3 User Tooling

SignalScope is split into two tracks: a reusable API runtime backend and a user-facing S3 CAN tool frontend.

Section layout includes:

  • /signalscope/api: backend API docs and integration patterns
  • /signalscope/s3: user workflow docs for reverse engineering and UI usage
  • Board portability guidance and single-core/dual-core notes
