What are the causes of chassis noise in the Volkswagen Bora?

Why is there a bulge in the rear of Volkswagen cars?

Volkswagen cars have a bulge in the rear due to the exhaust pipe or drive shaft located under the chassis. Typically, rear-wheel-drive vehicles require a drive shaft to transmit the engine's power to the rear wheels, necessitating this structural bulge. The Volkswagen Lavida has a body length, width, and height of 4670mm, 1806mm, and 1474mm respectively, with a wheelbase of 2688mm, and features front-engine, front-wheel-drive. It is equipped with a 1.4T turbocharged engine paired with a 7-speed dual-clutch transmission. This engine delivers a maximum power of 110kW and a maximum torque of 250Nm, and also incorporates direct fuel injection technology with an aluminum alloy cylinder head and block.

What is needed for the first maintenance of Magotan?

Items required for the first maintenance of Magotan include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice, to be taken to the designated first maintenance facility for the vehicle's initial service. Important note: make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after the new car has been driven, with the specific time varying by vehicle, generally around 5,000 kilometers. It is essential to attend the first maintenance on time, neither early nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard load and normal speed as required. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first serves as the standard. First maintenance items include: oil change, oil filter replacement, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Estimated time required: approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced. The selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different models specify different oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and scrubbing with a cloth. It is important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush with detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the cabin floor. Water entering these areas will not dry but flow through the holes to corrode parts like the gearbox. The better practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the existing antifreeze and add the same brand from the start. Different brands of antifreeze have varying chemical properties, and their corrosion inhibitors can react adversely when mixed, leading to unnecessary issues. Do not lubricate wheel bolts and nuts: When bolts on a moving car rust, they are often oiled to function again. Some people apply lubricant to wheel bolts and nuts to prevent rust, but this poses a safety risk. At high speeds, bolts and nuts can loosen or even fall off, causing driving failures. Do not press the accelerator when starting an EFI car: The starter of an EFI car differs from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and working conditions, ensuring a smooth start.

How Many Years Can a 10-Year-Old Used Car Last?

In good condition, it can generally last 3-4 years. Here are some precautions when buying a used car: Confirm the purchasing channel: When buying a used car, always choose a reliable channel. Inspect the car: Check the vehicle's exterior for any replaced parts, repainting, etc. If the car has been repainted, the redone paint may leave small bubbles or other imperfections. Test drive: A test drive is also a good way to inspect the vehicle, provided you communicate with the dealer beforehand. Generally, through driving, you can check for any abnormal noises or looseness in the interior, chassis, or suspension. You can also test the vehicle's acceleration, braking, gear shifting, etc., to determine its previous usage condition.

Does replacing the engine wiring harness require removing the engine?

Replacing the engine wiring harness does not require removing the engine. If the engine wiring harness is damaged, it can be directly replaced. A faulty engine wiring harness can cause inaccurate signals, which may prevent the vehicle from starting and could even lead to a fire. The wiring harness is the main network of the car's electrical circuits; without it, the car's electrical system would not function. Methods for inspecting the car wiring harness: 1. Visual Inspection Method: When a part of the car's electrical system fails, abnormal phenomena such as smoke, sparks, unusual noises, a burnt smell, or high temperatures may occur. 2. Instrumentation Inspection Method: This involves using comprehensive fault diagnostic tools, multimeters, oscilloscopes, current clamps, and other instruments to diagnose faults in the car's electrical circuits.

What Causes the Water Temperature to Rise When Braking?

It might be an issue with the thermostat; try replacing it. The problem could also lie with the thermostat or the water pump—when braking, the pressure in the radiator might cause the thermostat to close or the water pump to stop working. This situation could also be due to a short circuit in the wiring. Therefore, it's recommended to visit a repair shop to inspect the wiring harness, especially focusing on the engine compartment wiring harness, to check if poor grounding is the cause. Here are some additional notes: Caution: Keeping the car in D gear while braking for a long time can cause the transmission fluid temperature to rise very quickly. Since the transmission fluid is cooled in the radiator (there is a partition between the coolant and the transmission fluid), heat conduction can lead to an increase in water temperature. It's advisable to use P gear when parking for extended periods.

How many days in advance should I book the Subject 2 test?

Subject 2 test booking requires a 3-day advance reservation. Below is relevant information about Subject 2: Required materials for application: The applicant needs to register at the driving school and submit materials such as ID card and medical examination form. The driving school will collectively submit these materials to the vehicle management office for processing before the applicant can make an independent reservation. Currently, independent reservations are available from Subject 1 to Subject 4. Subject 2 test items: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. The car test items include five mandatory tests: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving along a curve.
