Compare Porsche ticking or rattling noise repair quotes from specialist garages

Porsche is known for its high-performance luxury sports vehicles - the best-selling model being the Cayenne. The company's founder, Ferdinand Porsche, created the world's first hybrid vehicle in 1899. It was called the Lohner-Porsche and was driven by electricity with a fuel-powered generator to charge the batteries, though it never made it into production.

Porsche continues to break new ground to this day; in 2017, the Cayenne S Diesel model earned the Guinness World Record for towing the heaviest vehicle, pulling an enormous Airbus A380 aeroplane weighing 285 tonnes.

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.
