Is it free to check engine failure at a 4S store?

[DelConnor]

Whether the car 4S store charges for inspection without repair depends on the situation. Generally, if the inspection is conducted within the warranty period, there is no charge. If the car is out of warranty, then a fee is required. Going to the car 4S store for fault inspection: Currently, the electronic control systems of cars are very advanced. As long as there is a vehicle fault, the onboard computer will generate a fault code. The car repair technician uses a computer to diagnose the fault code generated by the driving system, and then, based on the car owner's description, can quickly determine the location of the problem and provide targeted treatment. Car fault repair: When a car has a fault, it rarely requires the repair technician to dismantle the car and check the fault location bit by bit. Basically, the above method is used simultaneously. Therefore, if the car is out of warranty, going to the car 4S store for vehicle inspection is mostly charged.
