How many kilometers does the timing belt of Audi A6L2.0T need to be maintained? How soon does the spark plug need to be replaced? After driving 80 thousand kilometers, do you need to clean the throttle? The first problem is that the timing belt should be replaced every 60-80 thousand kilometers or every two years, whichever comes first. This belt is rubber. Even if you don't drive for one day, you should replace the car for two years, including the water pump and tensioner. The second question is that the ordinary spark plug is replaced at 40 thousand yuan, and the platinum is about 60 thousand yuan. The third question is whether the throttle valve needs cleaning to see if it is dirty. There is no prescribed mileage.
