After the system is evacuated, close the high and low pressure manual valves on the manifold gauge. Open the refrigerant tank valve, then loosen the nut at one end of the manifold gauge hose to allow gas to escape for a few minutes, then tighten the nut. Turn the high-pressure side manual valve to the fully open position and invert the refrigerant tank. Inject the specified amount of liquid refrigerant from the high-pressure side. Close the refrigerant tank charging valve and the high-pressure manual valve on the manifold gauge, then remove the gauge.

Does the Lavida consume engine oil excessively?

Volkswagen Lavida does not have excessive engine oil consumption. Oil consumption and burning engine oil are two distinct concepts: 1. Oil consumption: This refers to the inevitable phenomenon where a portion of the engine oil, which lubricates the pistons during combustion chamber operation, adheres to the cylinder walls and gets burned. As driving time accumulates, the oil level will naturally decrease accordingly, which is considered normal oil consumption. 2. Burning engine oil: This occurs when engine oil enters the combustion chamber and participates in combustion along with the air-fuel mixture. Signs of burning engine oil include blue smoke from the exhaust pipe, noticeable lack of power during acceleration, or checking the oil dipstick - as long as the oil level remains between the maximum and minimum marks between maintenance intervals, it is normal.

What Causes the Clicking Noise When an Audi Starts Moving?

A clicking noise when an Audi starts moving may be caused by the following reasons: 1. Hydraulic lifters: Air entering the hydraulic lifters due to low oil pressure or wear in the lifters themselves. 2. Valve clearance: Excessive valve clearance caused by wear in the valve rocker arms. 3. Dirty throttle body: Accumulation of sludge and carbon deposits leading to a dirty throttle body. 4. Carbon canister purge valve operation sound: This is a normal sound and the vehicle can continue to be used. If the noise is too loud, it is recommended to have it checked at a 4S shop. 5. Three-way catalytic converter: A 'clicking' sound within the first half-minute after a cold start, which then disappears, is usually due to the expansion of the three-way catalytic converter as it heats up.

What is the reason why the Audi Q5's brake pedal is hard and cannot stop the car?

It may be caused by external mechanical jamming or internal oil circuit blockage (possibly located in the oil cylinder area). Below is relevant information: 1. Definition: The Audi Q5 is a dynamic and versatile SUV. With its excellent performance and technological advantages, the Michelin Pilot Preceda PP2 high-performance sports tire has recently become the original equipment tire for the premium midsize SUV Audi Q5. 2. Introduction: The Audi Q5 is a midsize SUV model developed based on the production platform of the Audi A4. The stylish exterior of the Audi Q5 continues the design style of the Audi Q7, featuring the brand's signature chrome-plated "large grille," highlighting its fashionable and dynamic design. The integrated headlights make it look more lively compared to the A4 model. The rear design of the Audi Q5 combines the styles of the Audi A3 Sportback and the new A4. In terms of interior space, the Audi Q5 is slightly more compact than the Audi Q7, accommodating only five people.

What does the Lavida dual warranty mean?

The meaning of a vehicle's dual warranty is that the vehicle has two 3-year warranty periods, totaling 6 years of warranty coverage. Below is relevant information: 1. Introduction: The automobile three-guarantee policy is an abbreviation for "repair, replacement, and refund" implemented by retail businesses for the goods they sell. It refers to a credit guarantee method adopted by the seller for the items purchased by the buyer within a certain period after the goods enter the consumer market. 2. Scope of application: All newly launched vehicles for sale must provide a warranty period of no less than 3 years or 60,000 kilometers. Any quality issues that arise within the warranty period can receive free repairs, including parts and labor costs. The conditions for this warranty period are generally an "or" relationship, meaning there are two conditions for free warranty service: one is within 3 years of driving time, and the other is within 60,000 kilometers of driving distance. If either of these two conditions is exceeded, the vehicle cannot receive free maintenance and repairs.

What is the fuel consumption per 100 kilometers of the Trumpchi GS8?

The Trumpchi GS8 has a combined fuel consumption of approximately 10.7 liters per 100 kilometers. The GS8 is equipped with two engines: one is a low-power version of the 2.0-liter turbocharged engine, and the other is a high-power version of the 2.0-liter turbocharged engine. The low-power version of the 2.0-liter turbocharged engine has the model code 4B20M1. This engine has a maximum power of 148 kW, a maximum torque of 320 Nm, a maximum power speed of 5200 rpm, and a maximum torque speed range of 1750~4000 rpm. The engine uses multi-point injection technology and features an aluminum cylinder head and a cast iron cylinder block. The high-power version of the 2.0-liter turbocharged engine has a maximum power of 185 kW, a maximum torque of 390 Nm, a maximum power speed of 5250 rpm, and a maximum torque speed range of 1750 to 4000 rpm. This engine is equipped with DCVVT technology and uses an aluminum cylinder head and a cast iron cylinder block. This engine is paired with a 6-speed automatic manual transmission. The front suspension of this car uses a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during a cold start, requiring more gasoline to burn, which increases fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.
