The BMW 3 Series uses Harman Kardon audio system. Maintenance tips for BMW 3 Series audio system are as follows: 1. Head unit: The circuit board and plastic components in the head unit are significantly affected by weather conditions. The parameters of electronic components on the circuit board vary with temperature changes. Therefore, when the car interior temperature is high, it's advisable not to turn the volume too loud, as this not only affects sound quality but also reduces the system's lifespan. 2. Mechanism: The mechanical part consists of metal and plastic components combined with circuit boards. Since metals and plastics have different specific heat capacities, they respond differently to temperature changes. When the car interior is very hot, avoid rushing when changing CD discs - let the mechanism operate automatically without applying force. For multi-disc changers, don't repeatedly press the disc change button; allow the system to control the operation automatically.

Is an Appointment Required for Subject 4?

Subject 4 does not require an appointment. Subject 4, also known as the Subject 3 Safety and Civilized Driving Knowledge Test, must be taken on the same day after passing the Subject 3 Road Driving Skills Test. In some regions, applicants can simultaneously schedule appointments for both Subject 2 and Subject 3 Road Driving Skills Tests. If the appointments are successfully made, the tests can be taken consecutively. After passing both Subject 2 and Subject 3 Road Driving Skills Tests, applicants can take the Subject 3 Safety and Civilized Driving Knowledge Test on the same day. Additional Information: 1. The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates: Article 38: Applicants learning to drive on training grounds and roads must obtain a Learning to Drive Certificate as required. The Learning to Drive Certificate is valid for three years, and applicants must complete Subject 2 and Subject 3 tests within this period. Those who fail to complete the tests within the validity period will have their previously passed subject scores invalidated. The Learning to Drive Certificate can be in paper or electronic form, both of which hold equal validity. Applicants can print or download the Learning to Drive Certificate via the Internet-based Comprehensive Traffic Safety Service Management Platform. 2. Article 44: Each subject test allows one retake for those who fail. Those who do not take the retake or fail the retake will have their current test session terminated and must reschedule the test. However, Subject 2 and Subject 3 tests can only be rescheduled after ten days.

What to Do If You Fail the Driving Test Five Times?

If you fail the driving test five times, you must either re-register and pay for training again or choose to give up. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" issued by the Ministry of Public Security, during the validity period of the driving skill test permit, the number of scheduled tests for the subject two (road driving skills) and subject three (practical driving test) must not exceed five times. If a candidate fails the fifth scheduled test, the results of other subjects that have already been passed will be invalidated. More details are as follows: 1. The driving test consists of four parts: subject one and subject four are theoretical tests; subject two and subject three are practical driving tests. There is no limit to the number of times you can schedule the theoretical tests (subject one and subject four). For the practical driving tests (subject two and subject three), each subject can only be scheduled five times, but each scheduled test includes one retake opportunity on the spot. This means there are ten test opportunities for each of subject two and subject three. 2. The passing score for subject one and subject four is 90 points. For the C1 driving license test, subject two requires a score of 80 points or above to pass. Subject three, commonly referred to as the road test, requires a passing score of 80 points for the C1 test. As long as the required score is achieved, the test is passed.

Can a small chip in car paint be repaired?

A small chip in car paint can be repaired. The methods for repairing car paint are as follows: 1. Minor scratches on the body: If the damage is only on the surface layer of the paint, it can be completely repaired by waxing. 2. Damage to the body paint: If the scratch is slightly deeper and some of the paint has been scraped off, but the primer is not damaged and there is no serious deformation, the paint can still be well restored by waxing. 3. Damage to the primer and deformation: If the scratch on the car body appears white, it indicates that the scratch has reached the primer. To repair this type of paint damage, the corresponding area of the paint must be sanded off, followed by body repair, and finally, repainting with the various layers of paint. The cost of painting and repairing different car parts varies; paint is also divided into imported and domestic paint. For high-end imported models, it is recommended to use imported paint.
