Haldex Gen 5 controller
Factory manners.
Your rules.
In Stock, your car drives exactly as it left the factory. When you want more, you decide how much the rear axle joins in, and switch it with the buttons already in your car.
Why GripLink
Works with your Haldex, not around it
Stock means stock
Leave it in Stock and the car is exactly as the factory made it. Nothing is flashed or coded, and unplugging it returns the car to standard.
OEM+
The factory system keeps its own judgement, with sharper reflexes. It locks up sooner and harder in the moments it would anyway.
Your car's own buttons
Press the ESP button and your chosen mode is ready. Hazards on and it drops straight to front-wheel drive. Everything switches back by itself.
