It depends on the price and the level of cover. As a minimum, I would expect it to cover the air conditioning, brake system components, clutch components, cooling systems, diesel particulate filters (DPFs), electrics, engines, gearboxes, sat nav system, flywheel, ignition, steering, turbochargers and suspension.

You might save money and get better cover by taking out an independent warranty. For more information, see:www.honestjohn.co.uk/cheap-car-warranties/
