Owners of modern diesel vehicles, such as Volkswagens, will have noticed a blue AdBlue® cap next to their diesel cap. It can be helpful to know exactly what AdBlue is and how it's helping your vehicle to reduce its effect on the environment.

Volkswagen have come up with a clever solution to assist in solving this problem... Trailer Assist! When needing to reverse a trailer with a boat or caravan attached, all the driver needs to do is put the vehicle into reverse, press the Park Assist button and use the mirror adjustment buttons to enter the direction in which the trailer needs to follow. The vehicle will now steer automatically with the trailer on the back, however the driver is still responsible for gear-shifting, acceleration and braking.
