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.

Ticking and rattling are two closely related noises you might hear from your car. If you listen closely to where the sound is coming from and when it happens (while accelerating, for instance), you might be able to work out the cause.

The first thing to check is whether the engine oil is low, requiring a top-up - this is the best-case scenario. If your car is rattling and the sound is coming from the engine, it could be caused by a loose serpentine belt or timing chain. From the car's rear, it might be a loose exhaust or a broken catalytic converter, and the other possibility is worn suspension, which can cause rattling from the front or rear of the vehicle.

Possible explanations for ticking include worn spark plugs, knocking engine rods, dirty valve lifters and misaligned valves. You can learn more about these issues here.

Ticking and rattling noises should be taken seriously as they sometimes indicate a problem with the engine that could cause further damage if ignored.
