Audi shaking when starting cold may be caused by: insufficient temperature inside the engine, large spark plug gaps, or aging ignition coils. The solutions include: keeping the engine warm and regularly cleaning the fuel system. Audi is a luxury car brand under Audi AG, a subsidiary of the Volkswagen Group in Germany, representing classic car models. The company is headquartered in Ingolstadt, Germany, and has subsidiaries in many countries including China. Taking the Audi A6L as an example: it is a car series developed by FAW-Volkswagen Audi based on the new A6 in Germany, with a body length, width, and height of 4915mm, 1874mm, and 1455mm respectively, and a wheelbase of 2912mm.

The most common cause of Audi's cold-start shaking is the aging of engine mounts, also known as engine mount bushings. Rubber components harden and crack over time, especially noticeable in cold weather, where you can feel the steering wheel and seats vibrating as soon as the car starts. Last time I encountered this issue, I couldn't even balance a coin on the steering wheel at idle. Additionally, aging transmission mount bushings can cause similar problems, with a noticeable 'clunk' during initial acceleration. It's recommended to focus on inspecting these rubber support components—replacing them can make the car feel brand new. For models with start-stop functionality, if shaking is accompanied by a 'click' sound during start-stop cycles, it's almost certain the engine mounts are to blame.

How to Deal with Paint Spots on a Car?

Solutions for paint spots on a car: 1. Soak a towel in thinner and gently wipe the paint spots. Thinner can dilute the paint and is effective in cleaning paint spots. Rinse with clean water afterward. However, thinner is toxic, volatile, and somewhat corrosive, which may damage the car paint, so extra caution is needed when using it. 2. Gasoline can dissolve paint effectively and has minimal corrosion. The steps for use are the same as with thinner. 3. Alcohol can be used to wipe away paint. Dip a soft cotton cloth in alcohol and gently wipe the paint spots. 4. Essential balm can dissolve paint and can also be used to clean paint spots, with the same method as alcohol.

Can You Make a U-Turn Over Double Solid Yellow Lines?

Making a U-turn over double solid yellow lines is not allowed and constitutes a traffic violation. According to the "Road Traffic Safety Law," violators will be fined 200 yuan and receive 3 penalty points. On long roads, solid white or yellow lines (or dashed lines) are typically marked in the middle sections or before intersections. U-turns are prohibited wherever solid lines are present. Permissible U-turn scenarios: U-turn allowed at intersections with U-turn signs: If there is a clear U-turn sign at an intersection, a U-turn is permitted. If there is a U-turn traffic light, follow its instructions. In the absence of a traffic light, assess the situation and make a U-turn only if it does not obstruct other vehicles or pedestrians. U-turn allowed where no explicit prohibition exists: If there are no signs explicitly prohibiting U-turns or left turns, a U-turn is allowed. "No explicit prohibition" means the intersection lacks signs like "No U-Turn," "No Left Turn," or solid center lines, in which case U-turns are permitted. U-turn allowed over yellow grid lines: Yellow grid lines indicate no-stopping zones, typically painted at intersections prone to congestion due to temporary stops, important facility entrances, or other critical locations. Stopping on these lines (including waiting at traffic lights) is a violation. However, while parking is prohibited in yellow grid zones, U-turns are allowed unless there is a central barrier. U-turn allowed with a U-turn traffic light: If a dedicated U-turn traffic light is present, proceed only when it turns green. U-turn allowed despite "No Left Turn" signs: A "No Left Turn" sign does not necessarily prohibit U-turns unless explicitly stated. Important U-turn precautions: Check road markings: Never attempt a U-turn over solid lines under any circumstances. Continue driving until a suitable location is found. "No Left Turn" signs implicitly prohibit U-turns: Even if "No U-Turn" is not posted, a U-turn is impossible at such intersections since the maneuver requires a left turn first. U-turns must be made from the innermost left-turn lane: U-turns are prohibited if initiated from the second left-turn lane. Yield to straight-moving traffic: Always prioritize vehicles going straight to avoid accidents and liability. Lane arrow guidance: The leftmost lane may not always have a left-turn arrow. If marked with a straight arrow, U-turns are forbidden even without explicit prohibitory signs. No U-turns on crosswalks: Making a U-turn on pedestrian crossings is also a violation.

How to Brake Properly While Driving

Methods for braking while driving: Pay attention to turning signs on the roadside before making a turn, brake gradually and downshift while turning. For manual transmission vehicles, it is recommended not to brake while steering in curves to avoid skidding. If an obstacle is detected ahead, first activate the turn signal, release the accelerator, then gently apply the brakes to reduce speed while checking the rearview mirror for traffic conditions behind, and find the right moment to change lanes. Additionally, even for cars equipped with ABS and airbags, avoid slamming the brakes all the way down as this can cause severe damage and excessive wear to brake discs and pads.
