When should I service my Audi A6 Mk4?
Generally, the A6 uses a service indicator to let its owner know when the car needs a service, though even so, an oil and filter service should be carried out at least every two years or 15,000km, whichever comes first. Every three years the brake fluid should be replaced, the cabin filter should be done every two years or 30,000km and at 60,000km it is recommended to replace the fuel filter and the automatic transmission fluid (and its oil filter, too if it's the dual-clutch gearbox). The air filter lasts 90,000km. If for some reason the car is on a fixed interval service, then the oil service is due every year or 15,000km and for the petrol engines, the spark plugs should be replaced every 90,000km or six years.
Does the Audi A6 Mk4 have a timing belt?
The TFSI petrol engines and the V6 TDI diesel all use timing chains. The 2.0 TDI diesels use timing belts and they must be changed every 210,000km, regardless of time.
