Every car has carbon deposits. It is not recommended to clean carbon deposits if there is no problem. The return on investment is not proportional. Many cars have been damaged by themselves. For 95% of the current scenarios of cleaning carbon deposits, I think it is unnecessary. If you want to clean the carbon deposits on your 4S, you need to give a certain price based on the make and year of your car as a reference.
4S stores generally charge between 200-800 for cleaning carbon deposits, but please pay attention to the problems inside:
1. Clean the throttle without disassembling it, spray the cleaning agent directly on the rag, and then wipe it off. In this case, it cannot be cleaned.
2. Washing the fuel injector and pouring the cleaning agent directly into the fuel tank will not clean it.
3. Do not look at the carbon deposits in the spark plugs, and do not diagnose the working conditions of the engine
After buying a new car, if you park it in a 4S shop, will the people in the 4S shop do anything to the new car? This question can be clearly told to you, no, unless you are mentally retarded, I will explain it in detail from my personal point of view below.
First, the 4S store is directly owned by the manufacturer and has authoritative after-sales service. If you are found to have dismantled or assembled your car, you will face legal penalties. If you do so, you will be compensated two for one, and the manufacturer will directly remove the 4S store.
Secondly, those who can open a 4S store are quite powerful in terms of capital and connections, so they will not be greedy for this small advantage and take this risk.
Third, after buying a new car, go through all the procedures and maintain it, drive it home directly and keep it by yourself. Why should you put it in a 4S store?
Summary, take good care of personal things, do not have the intention of harming others, and do not have the intention of guarding against others!
I think it is better to go to a 4S shop for maintenance, because from my experience, some repair shops outside are generally larger and some are smaller. These repair shops generally do not pursue repeat customers and have no sense of responsibility. Although the maintenance cost is less than that of a 4S shop, it only involves changing the engine oil.
Let’s talk about the maintenance of the 4S shop. The car I drove before was a Dongfeng Honda. It was very cheap to maintain it outside for more than 300 yuan, and the 4S shop was about 500 yuan. Once I wanted to do maintenance outside for a cheap price, but I lost the battery clip in the engine compartment. When I asked, I said I didn’t see it. I was almost furious! Later, I almost always did maintenance at 4S stores. In fact, it was not that expensive. 4S stores often held events and the event prices were very cost-effective!
What the 4S store pursues is service and quality. Indeed, they will perform a full-body inspection on the car there and use engine oil that is suitable for the engine. It is not necessarily expensive or the best brand of engine oil, but the engine oil that is suitable for the engine is the best. For my car, the 4S store uses Dongfeng Honda XRV-specific engine oil, which is not available outside!
