What is the stop-start fault?

How many months in advance can a vehicle undergo its annual inspection?

Vehicles can undergo their annual inspection up to three months in advance. Below are the relevant details about the annual inspection: Conditions: Vehicles whose condition does not match the records on the driving license or archives, or whose license plates or driving licenses are damaged, incomplete, illegible, or self-made. Notes: The vehicle's exterior must not be modified. The color of window sunshades or anti-explosion films cannot be too dark (items inside the vehicle must be clearly visible from one meter away; this mainly applies to vans and trucks, but does not affect small cars with fewer than five seats). Vans and trucks must have enlarged rear license plate numbers. The number of spring leaf plates cannot be increased or decreased. The number of seats in a van cannot be more or less than specified. A fire extinguisher must be present. The cargo compartment of a box truck cannot be modified (no side doors, no roof openings, no tailgates). The size of the tires cannot be altered, and the tread patterns of tires on the same axle must be consistent. Vehicles with unresolved traffic violations or those impounded by the court cannot undergo the annual inspection.

What are the effects of water submersion on a vehicle?

Water submersion can have the following effects on a vehicle: Interior mold: Most car interiors are made of water-absorbent materials, and rainwater contains numerous impurities and bacteria. The enclosed nature of the vehicle's interior creates an environment conducive to mold growth. If interior components are not promptly cleaned and dried, fabric and leather surfaces may develop mold spots, which not only affect appearance but also produce unpleasant odors and increase bacterial contamination. Engine damage: Many people attempt to forcibly start their vehicles to drive them out of flooded areas without confirming whether the engine has taken in water. If the engine is already flooded, forcing it to start can cause severe connecting rod deformation. In such cases, insurance companies often deny claims. Transmission failure: If water levels rise above the engine compartment, the transmission is highly likely to take in water. Once the transmission is flooded, the vehicle may experience slipping, shaking, or jerky gear shifts, potentially shortening the transmission's lifespan or even rendering it irreparable.

What parts need to be repaired after a vehicle is flooded?

After a vehicle is flooded, the following parts need to be repaired and checked: Battery; The negative terminal of the battery should be disconnected as soon as possible to prevent short circuits in various electrical components due to water ingress. Engine; Check the engine to see if water has entered the cylinders, as this can cause the connecting rods to bend and damage the engine. Brake fluid; Inspect the brake fluid, as water contamination can lead to brake failure. Transmission; Check if water has entered the transmission, as internal water ingress can cause the gear oil to deteriorate, potentially leading to severe gear wear. Engine oil; Examine the engine oil for water contamination, which can cause the oil to degrade, losing its lubricating properties and resulting in severe engine wear.

How long after vehicle painting can it be exposed to water?

In hot weather, it generally takes 6-7 hours, while in bad weather it takes about 12 hours. Additional information: Precautions: Do not wash the car for three days after painting to avoid leaving stains. If you choose quick touch-up paint, the vehicle can be exposed to water immediately after pickup and is not afraid of rain, because the UV clear coat used in quick touch-up paint is entirely high-molecular environmentally friendly resin. After UV lamp curing, it forms a mesh protective film that is heat-resistant, UV-resistant, dust-resistant, and highly flexible, making it waterproof and suitable for waxing. Car maintenance: A car's appearance is often the first thing people notice about a vehicle, and exterior care is an important part of car maintenance, specifically the preservation of the car's surface paint.

Is It Serious If Water Gets Into the Vehicle's Exhaust Pipe?

There is an impact. Water entering the exhaust pipe can lead to severe consequences such as water entering the engine. If only the exhaust pipe has water, it is essential to remove the accumulated water as soon as possible to prevent impurities in the water from clogging the three-way catalytic converter or damaging the oxygen sensor. To drain the water, simply increase the throttle to expel the water through the exhaust. Below is relevant information about vehicle wading: Introduction to Vehicle Wading: Vehicle wading, as the name suggests, refers to driving a vehicle on low-lying, waterlogged roads, passing through water. This generally occurs during rainy weather in low-lying areas where inadequate drainage leads to water accumulation on the road. Precautions for Vehicle Wading: Before wading, observe the road conditions carefully; during wading, maintain steady power; after wading, inspect the electrical system. If a car stalls in water, the primary reason is usually water entering the exhaust pipe, though in some cases, electrical damage may also occur. Once the car stalls, do not attempt to restart it, as this may cause water to enter the intake tract and damage the valves, potentially leading to severe engine damage. The vehicle should be towed to a 4S shop immediately for professional handling.

What Causes Abnormal Noises When Starting the Vehicle?

Abnormal noises during vehicle startup can be caused by low engine temperature, transmission failure, belt slippage, gear wear, etc. Low engine temperature: When the engine temperature is too low, it cannot function properly. The car's three-way catalytic converter expands when heated, leading to abnormal noises during startup that disappear after a while. This is a normal phenomenon caused by the expansion of the three-way catalytic converter. Transmission failure: One of the reasons for abnormal noises during startup is transmission failure, which causes internal gears to rub and produce noise. Worn engine belts or chains can also create friction or cause abnormal noises due to idling during startup. The solution is to replace the timing belt. Belt slippage: Over time, belts can stretch and become loose, leading to slippage and abnormal noises during ignition. The solution is to replace the car belt. Gear wear: This noise is caused by the meshing of the starter gear and the engine flywheel gear. Frequent use over a long period can result in severe gear wear, leading to misalignment and grinding sounds. The solution is to replace the gears.
