The tune-up is a routine maintenance procedure which is essential for the efficient and economical operation of your vehicle's engine. Regular tune-ups will also help prolong the life of the engine. A gasoline engine tune-up should include the following:
Volkswagen recommends a tune-up service every 15,000 miles (24,000 km). Keep in mind that not all of these procedures may be applicable to your car and not all procedures are performed at each interval. For example, the valves are not adjustable on all engines and it may not be necessary to replace the fuel filter at every interval. Refer to General Information And Maintenance for additional information of the services performed during this maintenance interval.
During the tune-up, it is a good idea to look around the engine compartment for problem areas and head them off before they get expensive. Look for fuel, oil and coolant leaks, deteriorating radiator and heater hoses, loose and/or frayed belts. These little items have the ability to develop into major headaches.
