Product Description

This is a refurbished original Siemens Haldex control unit with OEM number 1K0907554C, developed for second-generation Haldex AWD systems used in Volkswagen Group vehicles. The module manages rear axle engagement by controlling the hydraulic operation of the Haldex clutch and communicating with ABS / ESP and drivetrain systems.

What This Control Unit Does

  • Controls the Haldex coupling for rear-wheel engagement on demand
  • Communicates with the vehicle’s ABS / ESP and drivetrain modules
  • Monitors system operation and stores diagnostic trouble codes
  • Controls pre-charge pump activation and clutch pressure strategy
  • Supports stable AWD function in normal driving and low-traction conditions

A faulty Gen 2 Haldex ECU can cause total loss of rear drive, intermittent AWD operation, CAN communication errors, or ESP / ABS warning lights. This refurbished version is resealed with new silicone for durability comparable to a new module and is tested before dispatch.

ℹ️ Coding Support Online support is included in case the module needs to be coded after installation. If you need advice with diagnostics or setup, contact us and we will help you choose the correct procedure for your vehicle.

Great selection of parts. Reasonable pricing. Fast delivery and super service/support. My new Haldex ECU worked like a charm, once the car had recognised it (took a couple of restarts of the car and fault code clearing with OBDeleven). Highly recommend!
