There are many "traps" in the maintenance of 4S shops. How can I not be cheated?

I once met a friend who was maintaining a car. A corolla less than two years old has done 20,000 kilometers of routine maintenance for this car in a shop in 4S. After the after-sales consultant warmly received his friends, he directly listed the maintenance items of 10. Asked about the maintenance cost, and quoted a price of more than 2000 after sale. At that time, Fan didn't like it. Looking at the maintenance list carefully, it is found that in addition to the necessary maintenance items, many additional recommended maintenance items have been added: an antifreeze that is completely unnecessary to change, +300 yuan; Maintenance of air conditioning pipes, cleaning of throttle valves, fuel injectors and other "cleaning" items, +700 yuan.

You know, this car has only been more than two years, and it has only driven more than 20 thousand kilometers! These are totally unnecessary maintenance items. The essential items for normal routine maintenance of 20,000 kilometers are mainly the replacement of "three filters" such as engine oil filter and air conditioner filter element, and routine inspection such as cleaning air conditioner. Even if you do it in a 4S store, you usually only need 6 700 yuan. General automobile maintenance can be divided into two categories: minor maintenance and major maintenance. Minor maintenance refers to the daily maintenance of the car when it uses 5000~ 10000km. The simplest routine part of minor maintenance is "changing oil and filter" and other items. It's hard to be fooled into adding a lot of money to a vehicle that only needs semi-synthetic oil, synthetic engine oil.

Major maintenance refers to the medium maintenance after the car has traveled 20,000 kilometers. Possible routine items include: replenishing coolant, cleaning engine fuel system, brake pads, etc. , that is, various cleaning agents and additives. In fact, most cleaning agents and additives are optional items. Even if the owner wants to treat his car better, the same product can be solved at the price of 1/3 when he goes to the outside repair shop, which is the place with the greatest "moisture" in the routine maintenance project. However, if you are worried about the authenticity of the supply of goods in the repair shop, the owner can also buy it on a reliable platform and get it replaced in the repair shop, and the price will be given a certain discount. In addition, although oil cleaning is also one of the maintenance items, it is generally recommended to use vehicles with a mileage of more than 20,000 to 30,000 kilometers, and new cars are not needed. In fact, the most fundamental thing is to learn to refuse, so that it will not be "routine" by 4S stores.
