Consequences of not changing transmission oil: It will affect the performance of the car. During the use of the transmission, friction between metal components will generate debris and impurities. Over time, the transmission oil will become dirty, oil passages will become blocked, leading to rough gear shifting, poor transmission efficiency, weak acceleration, and to some extent, increased fuel consumption. The reduced effectiveness of transmission oil can easily cause poor lubrication, accelerated component wear, and corrosion of mechanical parts, thereby shortening the service life of the transmission. Transmission oil needs to be checked regularly and is generally replaced every 80,000 kilometers. Transmission oil serves to lubricate and clean the transmission, ensuring its normal operation.

Can 4S shops modify cars?

4S shops cannot modify cars. It is best to go to a professional modification place. For registered motor vehicles, it is not allowed to arbitrarily change the registered structure, construction, or characteristics. Unauthorized changes to the vehicle's appearance, engine performance, or adding a turbocharger are all prohibited. If the owner really needs to modify the vehicle, they must first apply for record at the vehicle management office before proceeding with the modification. According to the "Motor Vehicle Registration Regulations": Article 9 states that applying to change the body color, replace the body or frame of a motor vehicle requires filling out the "Motor Vehicle Modification Registration Application Form" and submitting legal certificates and proofs. The vehicle management office shall make a decision to approve or disapprove the modification within one day from the date of acceptance. For approved modifications, the owner of the motor vehicle shall submit the vehicle for inspection to the vehicle management office within ten days after the modification. The vehicle management office shall confirm the motor vehicle within one day from the date of acceptance, retrieve the original driving license, and reissue a new driving license. Notes on vehicle modification: Replacing the headlights with xenon lamps is safe for driving itself, but drivers must comply with the regulation to switch from high beam to low beam when approaching an oncoming vehicle at about 100 meters at night, so as not to affect the visibility of other vehicles. Adding spoilers, car stickers, body kits, or modifying car audio systems generally do not affect safety and are therefore permissible. Installing a sunroof reduces the safety performance due to changes in the roof structure and load-bearing capacity. Changes and modifications to the engine are considered major modifications and must be applied for.

Does an A2 driver's license require annual review if there are no demerit points?

A2 driver's license does not require annual review or submission of a medical examination report if there are no demerit points within one cycle. According to Article 70 of the Ministry of Public Security Order No. 139, motor vehicle drivers shall, in accordance with the provisions of laws and administrative regulations, regularly undergo review at the traffic management department of the public security organ. Drivers holding a license for large passenger vehicles, trailers, urban buses, medium-sized passenger vehicles, or large trucks shall undergo review at the traffic management department of the public security organ within 30 days after the end of each scoring cycle. However, if there is no demerit record within a scoring cycle, the review for that scoring cycle is exempted. Annual review considerations: During the annual review, the vehicle management office will inspect the vehicle's lights. If the vehicle's lights are found to be too dim or too bright, it will be deemed unqualified and will not pass the annual review. If the lights are too dim, check the light circuits and whether the bulbs are aged, and replace related components if necessary. If xenon headlights have been installed, it is recommended to restore the original headlights before the annual review to pass the inspection.

What are the precautions for buying a car with FAW Leasing loan?

FAW Leasing loan car purchase precautions are as follows: Need stable high income support: Without stable and relatively high income, it is difficult to maintain high monthly expenses, leading to financial imbalance or inability to afford payments. For families with mortgages, it is even more important to rationally weigh income and expenses to avoid impulsive consumption that could affect financial conditions and quality of life. Be cautious about zero down payment, low-interest rate, and other promotions: In fact, most of these promotions are based on raising car prices and increasing agent fees. Therefore, do not let small gains compromise consumer rights. Legal and reliable auto loan procedures should be processed at commercial banks or formal auto finance agencies that comply with the "Auto Finance Company Management Regulations." Do not forget to repay principal and interest on time: According to commercial bank regulations, borrowers should deposit the installment repayment principal and interest in advance in the settlement account. If the borrower fails to repay on time, the bank will require a certain amount of late fees and may take measures such as repossessing the mortgaged vehicle or holding the guarantor accountable. Additionally, the bank will record a negative credit history for the borrower, making future loan applications difficult or even leading to a "blacklist" by multiple banks.

How to Spray Water with Windshield Wipers?

To spray water with the windshield wipers, pull the wiper control lever (the lever on the right side of the steering wheel) toward the driver. Windshield wipers are tools installed on the front glass of motor vehicles to prevent rain and other debris from obstructing the view. The method for replacing wiper blades is as follows: 1. Remove the wiper arm. Lift the wiper arm to locate the clip position, press the clip, and slide the wiper arm off in a parallel direction along the inner side. 2. Replace the wiper blade. Before replacing, distinguish between the two ends of the wiper blade. Pull the wiper blade out from one end, remove the steel strip inside the old blade, and transfer it to the new wiper blade. 3. Locate the arrow direction marked on the inner side of the wiper arm and insert the new wiper blade into the arm. Remove the blade from the sealed end, using a flat-head screwdriver to assist in prying the clip position if needed, then remove the steel strip and transfer it to the new blade. 4. After replacing the steel strip, insert the new wiper blade in the direction of the arrow (the end with the notch should be inserted first). 5. Install the wiper arm by pushing it back in the parallel direction.

What is the solution for the p227900 fault code?

p227900 fault code refers to the intake system failure of the car. In this case, it is recommended to clean the throttle valve or remove carbon deposits from the engine. Here is some relevant information: 1. The meaning of the p227900 fault code is an intake system leak. Simply put, it means that external air enters the cylinder directly without passing through the air flow meter or throttle valve, and when the value monitored by the air flow meter deviates from the actual value, this fault code will be generated. It is recommended to inspect the intake system. 2. The p227900 fault code is more common in Volkswagen cars. The appearance of this fault code indicates that the airflow in the car's intake system is low, which means there is an intake system leak, and external air enters the cylinder directly without passing through the air flow meter or throttle valve to participate in the reaction. It could also be caused by a damaged air flow sensor.
