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-S3: Free Haldex AWD Controller for VW & Audi

OpenHaldex-S3 is a free, open-source Haldex controller for Generation 1, 2, and 4 AWD modules in Volkswagen and Audi transverse AWD vehicles.

Supported platforms include:

  • VW Golf R
  • VW R32
  • Audi TT
  • Audi A3
  • Audi S3
  • PQ-based AWD vehicles

OpenHaldex-S3 installs inline using factory connectors and requires no permanent wiring modifications.

Build cost: Under $50
Build time: Under 1 hour
Installation: Lift rear seat -> Plug in -> Drive

Users can configure AWD locking behavior by:

  • Throttle position
  • Vehicle speed
  • Engine RPM
  • Custom maps
  • Fixed torque split modes (50:50, 60:40, 100:0 and more)

OpenHaldex-S3 delivers advanced AWD control without harness modifications or closed-source hardware.

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-S3 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
