If your VAG Group vehicle , VOLVO, Jaguar LAND ROVER has four wheel drive it’s likely the real wheels are driven through a Haldex coupling
| The Haldex Coupling is a very sophisticated piece of engineering and it needs to be looked after with regular oil changes. This multiplate Coupling is submerged( wet clutch system) that engages upon slip and transfer power to the rear final drive; controlled by computer and built in fine engineering tolerances. A Haldex pump pre-charges the oil inside the unit allowing the multi plate coupling to engage faster. If dirty Oil and filter are not refreshed, performance will largely be affected by faulty pump and vehicle will experience engine power loss to the rear wheels It is recommended to refresh the Haldex Oil every 35 ,000 km and Filter replaced every 70,000 km. |
