Since it was founded in 1909, Audi has been at the forefront of automotive innovation. It was the first to conduct crash tests, one of the first to use a dual-clutch gearbox, and in 1921, became the first German manufacturer to make a production car, the Audi Type K, with left-hand drive.

Impressively, Audi is also the most successful carmaker in the history of the World Car Awards, winning 11 titles since 2005 and five World Performance Car Awards as of 2022. Find out whether Audis are expensive to repair in this guide or take a look at how their maintenance costs compare with SEAT and Skoda.

There are two types of parking sensors. Ultrasonic sensors emit high-frequency sound waves that bounce off objects, allowing the receiver to calculate how far away they are. Electromagnetic sensors work by creating an electromagnetic field around the vehicle and monitoring it for any disturbances. Both systems allow you to park more quickly and safely and give you greater confidence during difficult manoeuvres.

The most common reasons for parking sensor failure are bad wiring, dirt and debris, and a malfunctioning sensor. A specialist technician can advise you whether you need a parking sensor repair or entirely new parking sensors fitted.

Although some older cars do not come with parking sensors, most makes and models allow them to be installed. You could even install a parking sensor and camera to give you extra awareness of your surroundings.
