What to Do If You Forget the Annual Inspection for Your Private Car?

If the vehicle has exceeded the annual inspection deadline, the first thing to do is to stop driving it on the road and promptly complete the annual inspection procedures. For vehicles that have exceeded the inspection period by less than one year, no penalties will be imposed when completing the inspection procedures at the vehicle management department. Here are some precautions for the annual vehicle inspection: 1. Warm up the vehicle: During the inspection, the exhaust emissions will be tested for compliance, specifically the oxygen sensor and the three-way catalytic converter. Their optimal operating temperature is between 400 to 800 degrees Celsius, so warming up the vehicle in the external inspection area before the exhaust emission test can increase the pass rate. 2. Clean the vehicle body in advance: Before the annual inspection, the owner should clean the vehicle body, engine compartment, and chassis in advance. This not only provides convenience for the inspectors but also helps in passing the inspection.

Does the BMW 3 Series require replacing the oil pan when changing transmission fluid?

The BMW 3 Series requires replacing the oil pan when changing transmission fluid. The sludge deposited at the bottom of the oil pan contains carbonized transmission fluid and metal powder from transmission wear, which can cause significant damage to the gearbox. Therefore, the oil pan should be replaced along with the transmission fluid. Below are common transmission faults: 1. Oil leakage: Oil seeping from the transmission housing or oil pan can be caused by aging seals with poor sealing performance, or manufacturing defects leading to pinholes in the housing. 2. Engine stalling when engaging gear: Stalling when shifting into D or R may be caused by a damaged lock-up solenoid valve or a stuck lock-up control valve. 3. Locked gear: Incorrect input/output signals from the transmission, faulty components or circuits, or communication issues between the transmission computer and other system computers can cause this. 4. No response when engaging gear: The vehicle doesn't move after shifting into D or R and releasing the brake. This is often due to damage to the input shaft or reverse clutch, or failure of the D/R brake. 5. Abnormal noise: Unusual sounds from the transmission area during driving are usually caused by worn parts or improper installation of the transmission.

What to Do When the Car Floor Soundproofing Cotton Gets Wet?

Soundproofing cotton getting wet is definitely due to incomplete sealing of the car body. Here is the relevant information: 1. Inspection Methods: Check if the sealing strips are aged, cracked, or incomplete, leading to poor sealing and water ingress; whether the waterproof membrane inside the rear door trim panel is damaged, and recall if any repairs or modifications have been done that might have affected the waterproof membrane; check if the drainage holes on both sides of the sunroof are blocked. If blocked, rainwater cannot drain through the pipes, causing the water level to rise continuously until it overflows along the headliner and sealing strips, eventually reaching the floor soundproofing cotton. 2. Solutions: Call the 4S shop for a comprehensive vehicle inspection and to seal any leaks.

What are the possible reasons for water leakage under the car?

It could be due to aging or damage in certain pipes of the cooling system, a damaged radiator, or the air conditioning being turned on. Here are the specific explanations: 1. Air conditioning is turned on: If water leakage under the car is caused by the air conditioning being turned on, this is a normal phenomenon. 2. Radiator leakage: If the leakage is from the cooling system pipes or the radiator, it is recommended that car owners repair it immediately. 3. Water-cooled engine: Most cars use water-cooled engines, which rely on antifreeze circulating continuously within the engine to dissipate heat. 4. Two circulation paths for antifreeze in the engine: One is the major circulation, and the other is the minor circulation.
