What is the difficulty ranking of Subject 2 in the driving test?

The difficulty ranking of Subject 2 is as follows: reversing into a parking space, stopping and starting on a slope, parallel parking, curve driving, and right-angle turns. Below is an introduction to Subject 2: 1. Purpose of the Subject 2 test: The Subject 2 test mainly examines the candidate's ability to control the vehicle and park it in a semi-clutch state. The requirements for candidates are primarily technical skills and mindset, as long as there are no major issues during regular training. It also tests the candidate's sense of direction. 2. Content of the Subject 2 test: The test items for cars C1 and C2 include reversing into a parking space, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (some regions also include a sixth item: high-speed toll card collection).

Can You Apply Light Braking When a Vehicle Has a Flat Tire?

Yes, but do not brake too hard, as it may lead to dangerous situations like skidding or rollover. Here are the relevant details: 1. Solutions for a Flat Tire: In the event of a flat tire, the driver should slow down gradually while firmly gripping the steering wheel and turning it in the opposite direction of the flat tire to maintain straight-line driving. If a flat tire occurs while driving on the highway, move the vehicle to the right and transfer it to a safe area as soon as possible. 2. Tire Maintenance: Regularly and appropriately rotate the tires on the vehicle (ensure tire checks during primary and secondary vehicle maintenance) to maintain even tire wear and extend their service life; slightly larger outer diameter tires should be installed on the outer wheels.

What Are the Reasons for Low Engine Oil Pressure?

Engine oil pressure may be low due to insufficient oil quantity, low oil viscosity, or poor oil pump performance. Engine oil serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. If the engine oil pressure is low, it is necessary to promptly identify and resolve the issue. Detailed explanations: 1. Use of inferior oil: Sludge blockage caused by engine oil. After using inferior oil, sludge is prone to form inside the engine, which can block the oil passages. The solution is to switch to high-quality oil, preferably following the vehicle's oiling instructions. 2. Oil passage blockage: An engine with blocked oil passages will have reduced oil flow, which can easily lead to insufficient engine oil pressure. In this case, the blocked oil passages need to be cleaned. 3. Low oil viscosity: If the oil viscosity is too low, the oil pump cannot press the oil into the oil passages. The natural solution is to change the oil.

What kind of engine oil should be used for the 2021 Bora?

The Volkswagen Bora originally uses semi-synthetic engine oil with the specification SM5W-40. Below is relevant information about the Bora: 1. Product Features: 7 major upgrades + 5 additional configurations comprehensively enhance riding comfort. The 2011 Bora 1.4T model not only provides consumers with a significant improvement in driving pleasure through enhanced power and handling but also achieves a new level of riding comfort through comprehensive upgrades in interior and exterior design as well as configurations. It is reported that the 2011 Bora 1.4T model features 7 major upgrades and 5 additional configurations, including improvements such as a frameless wiper, rear-window antenna, split front grille, new wood grain interior trim, chrome package, aluminum brushed interior trim, and a redesigned leather steering wheel, as well as new additions like the choice of upper gray and lower black interior, USB port, Aux-in audio interface, secondary door unlocking function, and a driver-side sun visor with a vanity mirror. 2. Appearance Overview: The wheelbase of the 2011 Bora is 97mm longer than that of the previous model, reaching 2610mm, which is close to the wheelbase of many B-segment cars. This increase in wheelbase significantly expands the interior space of the 2011 Bora, with almost all the additional length used to improve rear seating space, greatly enhancing the comfort for rear passengers.

What Are the Reasons for a Sudden Increase in Fuel Consumption in a New Car?

The reason for a sudden increase in fuel consumption in a new car is a malfunctioning oxygen sensor, which requires inspection and repair at a 4S shop. Below is relevant information about the oxygen sensor: 1. Introduction: The oxygen sensor is used to detect the concentration of oxygen in the exhaust and sends feedback signals to the ECU. The ECU then adjusts the fuel injection volume of the injector to keep the air-fuel ratio of the mixture near the theoretical value. 2. Function: The sensor measures whether there is excess oxygen in the exhaust after engine combustion, i.e., the oxygen content, and converts this information into a voltage signal sent to the engine computer. This allows the engine to achieve closed-loop control based on the excess air factor, ensuring that the three-way catalytic converter maximizes the conversion efficiency of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) in the exhaust, thereby optimizing the conversion and purification of emission pollutants.

What is the valve-like warning light?

The valve-like warning light is the engine malfunction indicator. Below are the specific causes of engine malfunctions: 1. Sensor failure: Including coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, triggering the engine warning light. 2. Poor maintenance: Inadequate engine maintenance is the most common cause of engine warning light activation. Vehicles have specific maintenance schedules, and failure to adhere to these schedules combined with poor driving habits increases the engine's operational burden. 3. Fuel quality issues: This includes both fuel and engine oil. The fuel used in cars typically has specific octane ratings, while engine oil comes in semi-synthetic and fully synthetic varieties. Failure to use the required specifications can lead to engine wear over time. 4. Poor combustion mixture: Issues such as faulty spark plugs, ignition coils, fuel pump failures, or clogged fuel lines can cause poor combustion in the engine. This leads to carbon buildup or engine knocking, which the oxygen sensor detects and reports to the ECU, triggering the warning light as an alert.
