Does 4S Store Maintenance Include Carbon Deposit Cleaning?
2 Answers
4S store maintenance includes carbon deposit cleaning. Below are the specific details of 4S store maintenance items: 1. Engine system: Replace the engine oil and oil filter. Check if all lubricating fluids in the engine compartment are lacking and if related components are loose. 2. Lighting system: Check if the lighting system is functioning properly. 3. Vehicle tires: Check if the vehicle tires are excessively worn. 4. Shock absorbers: Check if the shock absorbers are leaking oil. 5. Vehicle chassis: Check if the vehicle chassis has any scratches, damages, looseness, or rust issues.
When it comes to whether 4S shops clean carbon deposits during maintenance, it's actually quite common but not automatically included every time. Carbon deposits mainly come from accumulated residual fuel or engine oil in the engine, which can affect acceleration and fuel consumption over time. During regular maintenance at a 4S shop, they will inspect the engine system, but cleaning carbon deposits is usually an additional service, such as using specialized cleaning agents or equipment. You need to request this service yourself, and it also requires an extra payment, ranging from a few hundred to over a thousand yuan. I often go to 4S shops myself and always ask them to add this service because I drive an older car and frequent traffic jams make it prone to carbon buildup. I recommend calling to confirm before going for maintenance to avoid a wasted trip. Also, try to avoid short-distance, low-speed driving in daily use, and using good-quality fuel additives can help prevent this issue.
