Audi A8 air suspension faults include water ingress into the air suspension system, and checking whether the filter on the compressor intake hose has water ingress. Working principle of air suspension: The air suspension mainly consists of a control computer, air compressor, pressure storage tank, pneumatic front and rear shock absorbers, and an air distributor. Functions of air suspension: Body level control, body level adjustment, and ADS function are achieved by using the air compressor to generate compressed air, which is then delivered to the air chambers of the springs and shock absorbers. Height sensors are installed near the front and rear wheels. Based on the output signals from these height sensors, the vehicle's computer determines changes in the vehicle height and controls the compressor and exhaust valve to compress or extend the springs, thereby achieving a damping effect and altering the vehicle's height.

Is the brake on the left and the accelerator on the right correct?

It is correct that the brake is on the left and the accelerator is on the right, whether it is a manual or automatic transmission model. The left side is the brake, and the right side is the accelerator. Many people may confuse the brake and the accelerator, which is more common in manual transmission models. Automatic transmission models do not have a clutch, only the brake and accelerator, both controlled by the right foot. As long as both feet are not used simultaneously, the possibility of confusion is relatively small. Place the heel directly below the brake pedal; when pressing the brake, it is pressed straight down. The accelerator is to the right of the brake. Without moving the heel, moving the toes to the right means pressing the accelerator at an angle. Drivers should develop the habit of placing the heel directly below the brake pedal so that they can brake at any time in case of an emergency.

What is the Difference Between Adaptive Cruise Control and Full-Speed Adaptive Cruise Control?

Adaptive Cruise Control and Full-Speed Adaptive Cruise Control differ in the following aspects: 1. Nature: Adaptive Cruise Control is an upgraded version of traditional cruise control; Full-Speed Adaptive Cruise Control adds start, stop, and intelligent control across the entire speed range based on Adaptive Cruise Control. 2. Function: Traditional cruise control allows the driver to maintain speed without pressing the accelerator; Adaptive Cruise Control offers higher automation and better adaptability to road conditions. 3. Operating Speed: Adaptive Cruise Control only works when the speed exceeds 25 km/h, requiring manual control below this speed; Full-Speed Adaptive Cruise Control features stop-and-go functionality, operating within a speed range of 0 to 150 km/h, can be activated from a standstill, maintains safe following distance, and follows the leading vehicle to stop and start, freeing the driver's feet.

How long after passing through ETC is the deduction made?

ETC deductions are made immediately after passing through. The accounts of the highway ETC management units are connected to the banks. When passing through a toll station, the station's network transmits the information to the highway management company, which then sends the vehicle's passing and fee deduction details to the bank. The bank then writes the deduction information to the corresponding card. Vehicles that evade tolls and are added to the ETC blacklist will be barred from using highways nationwide and will be charged based on the longest distance of the highway. If a deduction fails due to ETC device malfunction, you can take the ETC device (electronic tag) to an ETC service outlet or highway service hall for inspection. If the damage is not caused by human factors, the device can be reactivated or replaced.

How to Apply for a Temporary ID at the Train Station?

What does it mean when the engine oil light flickers on and off?

The engine oil light flickering on and off is a normal phenomenon during vehicle self-check. When the vehicle is powered on, the self-diagnosis system activates, causing the engine oil light to illuminate. After the vehicle runs for a while, if the system detects normal oil pressure, the light will automatically turn off. However, if the oil light flashes while driving, it indicates an oil system abnormality, requiring immediate parking for inspection or a visit to a 4S shop for maintenance. Possible causes for the oil light flashing include: 1. Insufficient oil level reduces the oil pump's output or causes air intake, leading to pressure drop; 2. Engine overheating accelerates oil aging, deterioration, and thinning, potentially causing leakage through gaps and pressure reduction; 3. A clogged oil filter can cause oil pump pressure fluctuations.

Why Is There Still a Charge for the Free First Maintenance?

First maintenance is not entirely free because not all services are included in the complimentary offer. The free items during the first maintenance are fixed, typically covering only engine oil and oil filter replacement. Services like engine cleaning or additional inspections incur charges. To avoid paying during the first maintenance, you can decline any extra services recommended by the 4S dealership. New cars usually come with a free first maintenance service, and some brands even offer the first two services for free. The complimentary maintenance items provided by 4S dealerships are specific—for example, the first maintenance is recommended when the car reaches 5,000 to 7,000 kilometers. Since the car has just completed its break-in period, only an oil and oil filter change is usually necessary. After the oil change, impurities generated during the break-in period inside the engine are effectively removed, allowing the engine to operate in better condition.
