Who to Contact When a Fully Paid New Car Lacks a Certificate of Conformity?

According to relevant regulations, a new car without a factory certificate of conformity cannot only be exempt from vehicle purchase tax but also cannot be registered and licensed by the traffic management department. In accordance with relevant laws and regulations, when consumers purchase a new car, the dealer must deliver not only the car itself but also the certificate of conformity, user manual, invoice, and other credentials to the consumer. After the vehicle purchase is completed and the consumer has paid in full, they can contact the dealer for resolution. Below is an introduction to the certificate of conformity: 1. Overview: The certificate of conformity is another important credential for a car and is essential for vehicle registration. Only cars with a certificate of conformity meet the national requirements for motor vehicle equipment quality and related standards. 2. Content: The purchase invoice is the most important proof when buying a car and is also one of the credentials required for vehicle registration. Therefore, when purchasing a car, you must request the purchase invoice from the dealer and confirm its validity. 3. Other Documents: Some vehicle engines come with a separate user manual, and certain optional equipment for some vehicles may have specific requirements or regulations. In such cases, consumers should request the relevant credentials from the dealer.

What is the difference between a 7-seater SUV and an MPV?

The differences between a 7-seater SUV and an MPV: 1. Styling differences: 7-seater SUVs still maintain the exterior characteristics of SUV models, while MPVs follow a more stable and business-oriented design. The appearance of the car can also easily distinguish between a 7-seater SUV and an MPV. 2. Different seating layouts: Generally, 7-seater SUVs have a 2+3+2 seating arrangement, while MPVs usually have a 2+2+3 layout. MPVs typically feature sliding doors, whereas 7-seater SUVs have traditional side-opening doors. The sliding doors in MPVs were originally designed to make it easier for rear passengers to get in and out. 3. Space differences: 7-seater SUVs usually have a body length of around 4.7 meters, while MPVs are generally about 4.9 meters long. 4. Handling differences: Although 7-seater SUVs have increased in size, their handling and off-road capabilities are not compromised, retaining a certain level of off-road performance. MPVs, on the other hand, are more conservative in terms of power and are tuned for comfort, focusing more on passenger experience. As a result, MPVs have relatively lower chassis and larger bodies, making them appear slightly bulky and less agile in handling compared to 7-seater SUVs.

Where is the charging port for the Audi A6 data cable?

The USB port of the Audi A6 is hidden in a box under the rear seat air conditioning. Open it to find a USB port and power supply. The Audi A6 does not have a USB port in the front row, only in the rear. The USB port of the Audi A6 is designed for data transfer. Below is the relevant introduction: 1. Working principle: The in-car power supply converts DC-12V or DC-24V to DC-5V, and then uses the unified USB interface to charge the corresponding electrical devices with the DC-5V output. Since different devices have varying power requirements, the power of the USB car charger also varies significantly, mainly differing in the current output of the USB car charger. 2. Precautions: To avoid damaging the vehicle's electronic devices, never connect accessories that output current to charge the vehicle's battery. Do not connect devices that use a voltage level different from the value indicated on the socket. Carefully unplug the connector from the power source to prevent damage. Improper use may result in serious injury or cause a fire. Therefore, when the key is left in the car, never leave children unattended in the vehicle to avoid injury risks.

What is the symbol for the heater?

The heater switch symbol is generally displayed as a "thermometer" or with red and blue color markers on both sides. By rotating the knob, the red area indicates gradually increasing temperature. Automatic air conditioning allows you to set a temperature and then press the AUTO button, where the system will automatically adjust based on the interior temperature of your car. Below is an introduction to the heater: 1. Principle: The main motor drives the plunger oil pump, combustion-supporting fan, and atomizer to rotate. The oil pump delivers the inhaled fuel to the atomizer via the fuel pipeline. The atomizer mixes the atomized fuel with the air inhaled by the combustion-supporting fan in the main combustion chamber through centrifugal force, which is then ignited by the glowing glow plug. After full combustion in the rear combustion chamber, the process reverses, transferring heat to the medium—coolant—in the water jacket interlayer through the inner wall of the water jacket and the fins above. The heated medium circulates throughout the pipeline system under the action of the circulation water pump (or thermal convection) to achieve the heating purpose. The exhaust gas from the heater is discharged through the exhaust pipe. 2. Function: Heats the engine's circulating medium—antifreeze—directly transferring heat to the interior radiator and defroster, providing a heat source for cold engine starts and cabin heating.

What Causes Difficulty Starting After Warming Up the Engine?

Reasons for difficulty starting after warming up the engine: 1. Fuel injector leakage: While fuel injection is normal, leakage constitutes additional fuel supply. The more severe the injector leakage, the richer the air-fuel mixture becomes, leading to hard starts when the engine is warm. 2. Damaged carbon canister purge valve: During warm starts, fuel atomization is already normal and doesn't require additional fuel vapor. If the carbon canister continues supplying vapor to the intake, it creates an overly rich mixture, making starting difficult. 3. Fuel quality: After shutting off a warm engine, the engine compartment remains hot. If the fuel is highly volatile, it can form excessive vapor pressure in the fuel rail. When this pressure exceeds the fuel system pressure, vapor lock occurs, causing overly lean fuel vapor injection and starting problems. 4. Intake air temperature sensor: Similar to the coolant temperature sensor, this sensor adjusts fuel injection. However, while a faulty coolant sensor causes cold start issues, a faulty intake air temperature sensor leads to warm start difficulties. 5. Engine carbon deposits: Carbon buildup strongly absorbs gasoline. Excessive carbon on intake valves, throttle bodies, or pistons can absorb fuel, creating an overly lean mixture that affects starting. This issue can also occur during cold starts.

Is the Audi Q3 Quattro authentic?

The new Audi Q3 is authentic and features full-time four-wheel drive. Below are the relevant details: 1. Positioning: The Audi Q3 is an SUV based on the same PQ35 platform as the Volkswagen Tiguan, positioned below the Q7 and Q5 in Audi's model lineup. To distinguish it from Volkswagen models, the Audi Q3 has been tuned for more dynamic driving performance and a luxurious, distinctive exterior. It will be equipped with adaptive dampers, similar to those found on the TT. 2. Powertrain: Audi initially offers three four-cylinder engines for the Q3. The standard gasoline model is equipped with a 170-horsepower 2.0TFSI engine, while the top-tier Q3 model features the 211-horsepower 2.0TFSI engine from the Q5, achieving a 0-100 km/h acceleration time of 6.9 seconds. The 2.0TDI diesel engine delivers a maximum power of 140 horsepower. 3. Full-time four-wheel drive: The Audi Q3 brakes before entering a turn, follows the mountain road's path to find the optimal line, and accelerates out of the turn. This series of maneuvers is perfectly matched with Audi's powerful Quattro full-time four-wheel-drive system, which ensures safety by providing strong traction after exiting the turn, allowing the driver to experience the joy of seamless control. The Quattro system demonstrates its robust capabilities on mountain roads, with excellent body stability and steering precision under the intervention of the S-Line suspension package.
