Every Haldex control unit sooner or later will fail causing the loss of the AWD/4wd system operation and the dreaded ESP light on the dashboard. The main cause of failure in this system is the Haldex control ECU which is bolted to the side of the rear differential by two hex bolts.

Haldex Controllers fail because the seals on the rear side of the ECU let salty road water to ingress inside the unit, which evaporates leaving a salt build up which eats away at the PCB inside causing components to fail and the PCB's tracks to corrode away to nothing.
