Compare Porsche electrical fault 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.

A car's electrical system has many components, including the starter motor, battery, alternator, indicators, lights, radio, power steering and heater. The battery stores electricity generated by the alternator and sends it to the vehicle's ancillary circuits.
