What Causes Severe Jerking in Mercedes-Benz 9-Speed Transmission?

Severe jerking in Mercedes-Benz 9-speed transmissions can be attributed to the following reasons: Persistent internal contamination: Transmission jerking often occurs not due to valve body damage, but rather from stubborn internal dirt and impurities. When these contaminants accumulate within the valve body, they can form blockages that prevent effective oil pressure regulation, leading to jerking, impact, and slippage issues. Transmission overheating: Overheating is another critical factor, accounting for over 90% of automatic transmission failures. High temperatures degrade transmission fluid quality and friction characteristics, increasing wear and generating noise. Additionally, sludge (impurities or contaminants) forms inside the transmission (e.g., in the valve body), causing jerking and harsh shifting.

Do I Need to Enroll in a Driving School to Retake the Test After My Driver's License is Revoked?

You need to enroll in a driving school to retake the test after your driver's license is revoked. If your license is revoked (but not suspended or canceled), you can schedule the test once your application conditions are approved, and there is no specified waiting period before retaking the test. During the one-year probationary period, if you accumulate 12 penalty points, your driving privileges for the probationary vehicle type will be revoked, regardless of the vehicle type. If your driving privileges are revoked due to accumulating 12 points, you must re-enroll and retake all test subjects to obtain a new license. The test subjects are as follows: Subject 1: Road traffic safety laws, regulations, and related knowledge. The exam question bank structure and basic question types are formulated by the Ministry of Public Security, while provincial traffic management departments establish their own question banks based on local conditions. Subject 2: Field driving skills, including test items such as reverse parking, hill start, right-angle turns, curve driving, and parallel parking. Subject 3: Road driving skills, including basic test items such as pre-driving preparation (walking around the vehicle counterclockwise, fastening seatbelt, turning on left indicator, shifting gear, releasing handbrake, honking), starting, driving straight, changing lanes, passing intersections, pulling over, crossing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving. Subject 4: Safe and civilized driving knowledge, covering related topics on safe and civilized driving.

Can Cola Be Used to Clean Headlights?

Cola can be used to clean car headlights. Methods of cleaning headlights with cola and the effects of not cleaning: Methods of cleaning headlights with cola: Pour cola onto the headlights, then wipe with a clean towel. If the effect is not obvious after one attempt, repeat the process multiple times. Finally, rinse with clean water and dry. Using cola to clean car headlights has a certain cleaning effect because cola contains acidic substances such as carbonic acid and citric acid, which can dissolve some rust and grease. Effects of not cleaning car headlights: Over time, the headlight covers will gradually become dirty, yellowed, and aged. If not cleaned, the light transmission will decrease, leading to dimmer car lights, affecting driving, and accelerating the aging of the headlight covers.

Solutions: Clean throttle body carbon deposits; Check if battery voltage is abnormal. Reasons for abnormal noise during cold start include: Poor operation of fuel tank exhaust valve; Fluid impact inside the return pump; Partial blockage inside the fuel filter. Engine: A machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc.

At a crossroads, should straight-going vehicles yield to left or right turns?

At a crossroads, yielding to either left or right turns when going straight is not in compliance with regulations. The correct yielding rules and related regulations are as follows: Correct yielding rules: The correct yielding rule is that turning vehicles must yield to straight-going vehicles. When straight-going vehicles encounter turning vehicles, it is the turning vehicles that must yield to the straight-going ones, not the other way around. If a traffic accident occurs because a turning vehicle fails to yield to a straight-going vehicle, the turning vehicle will bear full responsibility. Other related yielding regulations: If there are traffic signs or markings, yield to the party with the right of way; in the absence of traffic signs or markings, stop and look before entering the intersection and yield to vehicles coming from the right; for vehicles coming from opposite directions, right-turning motor vehicles must yield to left-turning vehicles.
