Audi A4L currently has China 5 and China 6 standard models on sale, and there is no further subdivision into China 6A or 6B yet. Introduction to China 6A and 6B: Currently, the country divides the China 6 standard into two phases, China 6a and China 6b, with plans to implement them nationwide in 2020 and 2023, respectively. On July 1st of this year, some cities have already started implementing the China 6 standard. Introduction to the Audi A4L: As an entry-level Audi model, the Audi A4L performs quite balanced overall. After all, it is designed for the masses, and only by being more balanced can it meet the different needs of various consumers as much as possible, catering to those who prefer the golden mean.

I recently bought an Audi A4L and specifically checked the emission standards. All brand-new Audi A4L models currently on sale comply with China 6b, with no China 6a versions available anymore. The China 6b standard is much stricter than China 6a—for example, carbon monoxide emissions are reduced by half, and particulate emission limits are more stringent. This change is mainly due to the national policy upgrade in July 2020, which required all newly produced gasoline vehicles to meet China 6b standards. As a luxury brand, Audi acted quickly and upgraded its engine technology early on. You don’t need to worry about emission issues when buying a new car. However, if you’re looking at a used A4L produced between 2019 and early 2020, it might still be China 6a. I recommend checking the vehicle conformity certificate when purchasing a car, as it clearly states the emission standard.

Current Audi A4L buyers don't need to worry about emissions at all, as all models uniformly meet China 6b standards. China 6b is significantly stricter than China 6a, primarily by lowering the emission limits for nitrogen oxides and particulate matter. Policy-wise, since July 2020, all new vehicles must comply with China 6b, and major manufacturers like Audi have certainly planned ahead. There's also a hidden benefit to buying China 6b vehicles: they tend to retain better resale value in the used car market, especially in cities with driving restrictions. I know Shenzhen started strictly enforcing China 5 vehicle bans in urban areas last year, while China 6b models remain unaffected. If you're considering a used Audi A4L, check the production date - those manufactured before July 2020 might only meet China 6a standards.

What is the valve adjustment method for the 430 Weichai P12?

430 Weichai P12 valve adjustment method: 1. Turn the engine to the compression top dead center of cylinder 1 (align with the OT mark, intake valve of cylinder 6 opens), adjust the intake valve clearance of cylinders 1, 2, and 4 to 0.4mm. 2. At the flywheel end, turn the engine counterclockwise to align with the "16" mark on the outer edge of the flywheel. First adjust the exhaust valve clearance of cylinder 1 to 0.5mm, then adjust the brake clearance of cylinder 1 to 1.35mm. 3. Continue turning the engine counterclockwise at the flywheel end to align with the "25" mark on the outer edge of the flywheel. First adjust the exhaust valve clearance of cylinder 5 to 0.5mm, then adjust the brake clearance of cylinder 5 to 1.35mm.

Is the Qashqai a three-cylinder or four-cylinder?

The Qashqai is a four-cylinder vehicle. Relevant details are as follows: 1. Exterior Design: The new Qashqai's exterior design is bolder and sharper compared to the new X-Trail, retaining the 'V' shaped front grille, a signature design language of Nissan, paired with sharp headlight clusters, leaving a lasting impression. The side profile of the new Qashqai is not overly adorned with lines but adopts the conventional rounded styling of urban SUVs, with a pronounced three-dimensional effect at the rear, though the overall aesthetic is somewhat understated compared to the striking front face. 2. Interior: Inside, the new Qashqai's cockpit resembles that of the new X-Trail, featuring a floating large-size display, a full LCD instrument panel, a three-spoke multifunction steering wheel, and an electronic gear shift, among other elements, with technological features and a sense of premium quality surpassing the current model. There are also corresponding upgrades in power. According to overseas market information, the new car will be equipped with a 1.3T four-cylinder engine, paired with a 12V mild hybrid system, with a maximum output of 138 horsepower for the manual transmission version and 156 horsepower for the CVT version.

When to Replace Transmission Fluid?

The transmission fluid in a car should be replaced every two years or every 40,000 kilometers, with the specific interval depending on the vehicle model. The hazards of not replacing transmission fluid in time: 1. Deterioration of transmission: Prolonged operation under high-speed and high-temperature conditions can cause the transmission to deteriorate. A deteriorated transmission will accelerate the wear of mechanical components, and severe deterioration may even damage internal transmission parts. 2. Weak vehicle acceleration: If the transmission fluid is not replaced for a long time, the vehicle may experience weak acceleration when starting, along with slight slipping during driving. 3. Increased transmission wear rate: If the transmission fluid is not replaced for an extended period, it will become thicker, obstructing the transmission cooler. This obstruction leads to rising transmission temperatures, which in turn accelerates the wear rate.

How to Deal with Severe Low-Frequency Noise After Soundproofing?

Severe low-frequency noise after soundproofing is likely due to the use of incorrect soundproofing materials. It is recommended to use white sound-absorbing cotton (white cotton, Shirley cotton, ultra-fine fiber cotton), which can effectively absorb low-frequency noise waves generated externally or internally. Relevant details are as follows: 1. Avoid full coverage: If vibration damping sheets are chosen as the soundproofing material, do not opt for full coverage. While full coverage of vibration damping sheets can eliminate high-frequency noise during driving, the main noise inside the car is low-frequency noise. Therefore, using full coverage vibration damping sheets will not significantly reduce noise. 2. Counterproductive: Do not assume that more soundproofing projects will yield better results. If vibration damping sheets are applied along with additional sound-absorbing layers like white cotton, it may have the opposite effect, leading to noticeable low-frequency noise and even symptoms like dizziness and tinnitus.

What is DSG Transmission Death Flashing?

DSG transmission death flashing refers to a malfunction in the DSG transmission where the gear indicator continuously flashes, gears cannot be used normally, shifting becomes difficult, and the transmission temperature rises rapidly. DSG Introduction: DSG refers to the transmission model used by Volkswagen. DSG (Direct-Shift-Gearbox) translates to 'Direct Shift Gearbox' in Chinese. Unlike conventional semi-automatic transmission systems, DSG is based on a manual transmission rather than an automatic transmission, making it a member of the AMT (Automated Manual Transmission) family.

What are the causes of friction noise when turning the steering wheel of an Audi Q5?

Here are the reasons for the friction noise when turning the steering wheel of an Audi Q5: 1. Lack of oil in the shock absorber's plain bearing: Listen near the hood to determine if the noise is coming from the top mount of the shock absorber. If the noise is from the plain bearing of the shock absorber, applying some grease to the plain bearing may help. If the noise persists after greasing, replacement is necessary. 2. Loose stabilizer bar bushings: Check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noise not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, but damaged ones must be replaced.
