Syvecs SYV-4WD-HALP-VAG is a professional standalone AWD/4WD controller module for the MQB platform Haldex all-wheel drive system. It is designed for Audi S3, VW Golf R7.1 and R7.5 models where the standard Haldex controller is locked without adjustment options. With the Syvecs controller, AWD torque control can be fully optimized according to the power level and application of the project.

The system is particularly suited to track, sprint and high-performance street builds where standard AWD logic limits traction control and performance.

Key features

Full Haldex AWD torque control

• Adjustable front/rear wheel drive distribution for different situations

• Map-specific AWD strategy for different grip conditions

• Possibility of 2WD / burnout mode

• Duty maps and limiters for controlling Haldex solenoids

• Optimizing AWD strategies for high power levels

The Syvecs controller replaces the OEM Haldex logic and enables fully customizable AWD operation.

Driving control & performance

• Better grip for track, sprint and winter use

• AWD strategies with traction control and launch control functions

• Map change with Drive Mode button (AWD Select maps)

• Optimized torque distribution based on speed, load and G-forces

The system uses vehicle CAN data such as steering angle, brake pressure, RPM, TPS, G-forces and wheel speeds to generate precise AWD strategies.

Safety & Security

• Limp protection for slip, current and temperature

• AWD remains active in critical situations

• Overheating and overcurrent protections

• Cooling pump control

The OEM Haldex controller can disengage AWD under load, but Syvecs safely maintains control even at high power levels.

Data & adjustment

• Over 40 adjustable maps for AWD strategies with SCal software

• Sending CAN data to other ECUs and instrument clusters

• Support for external sensors and adjustment potentiometers

• Works with any motor control

The Syvecs controller replicates OEM CAN data and allows for complete integration into the car's systems.

Why Syvecs AWD Controller for the MQB project?

The MQB Haldex all-wheel drive is designed for standard power. In high-power turbo or racing builds, the precision of AWD torque control determines traction, driveability and drivetrain durability.

Syvecs SYV-4WD-HALP-VAG offers:

• Full control over the Haldex AWD system

• Better starts and better traction control

• Optimized AWD strategy for track and sprint use

• Full integration with Syvecs ECU systems

Aptitude

• Audi S3 (MQB AWD)

• VW Golf R Mk7 / Mk7.5

• Seat Leon Cupra AWD models

• High-performance street, track and sprint projects

Note: Not compatible with RS3 / TTRS models.
