What to Do When the Engine Fault Light Comes On After an Oil Change?

Changing the oil is just a routine maintenance task and is not directly related to the engine fault light coming on. The main reason for the engine fault light illuminating is poor engine combustion conditions. Special cleaning agents can be used to remove carbon deposits, and high-quality fuel additives can be employed to clean the entire fuel system. More details are as follows: 1. The engine fault light (also known as the MIL light) comes on when components monitoring vehicle exhaust emissions fail, and the On-Board Diagnostics (OBD) system detects excessive emissions. Examples include the ignition coil, spark plugs, catalytic converter, exhaust valve, fuel injectors, intake pressure sensor, oxygen sensor, etc. 2. After the engine fault light comes on, there may be some abnormal conditions. If not addressed promptly, it can lead to issues such as increased combustion chamber temperature and accelerated wear, potentially causing premature engine damage. Engine noise may increase, affecting driving and passenger comfort. Fuel consumption may rise, wasting petroleum and financial resources. The engine may burn oil. Vehicle exhaust quality may deteriorate, polluting the environment. To maintain the engine in good working condition, car owners can opt for high-quality gasoline, which usually resolves the issue of the engine fault light coming on.

What is the principle of engine exhaust braking?

The principle of engine exhaust braking: Utilizing the vehicle's own kinetic energy to compress air during the intake stroke, an additional mechanism opens the exhaust valve when the piston reaches the top dead center, expelling the compressed high-temperature and high-pressure gas from the cylinder. This prevents the compressed air from performing work on the piston during the next power stroke. Exhaust braking is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and closing this valve increases the pressure during the exhaust stroke, generating braking force through the resulting negative pressure. The regulating valve is typically driven by a control mechanism and often shares the same power source as the main brake system.

How to Replace the Brake Pads on a Magotan?

Volkswagen Magotan Brake Pad Replacement Steps: 1. Before replacing the brake pads, open the cap of the brake fluid reservoir in the engine compartment to check the brake fluid level. If the brake fluid level is above the maximum limit, some fluid should be siphoned out to prevent overflow during the replacement process. 2. Prepare the new brake pads for replacement and remove the wheel where the brake is located. Be careful to avoid scratching the rim during the removal process. 3. Use a wrench and socket to remove the bolts of the brake caliper, then take out the brake pads (if there is a brake sensor wire, remove it first). Check if the brake pads are excessively worn or have cracks, and proceed with the replacement if necessary. 4. Since the brake caliper may have a lot of sand or dirt, clean it thoroughly with a cloth and apply anti-squeal paste to prevent noise during braking. 5. Use a piston press to push the piston to its limit, then install the new brake pads onto the caliper. After installing the new brake pads (and reconnecting the brake sensor wire if applicable), tighten the guide bolts to complete the installation. 6. After installation, securely close the reservoir cap, get into the car, and press the brake pedal several times to reset the brake. Then check the brake fluid level to ensure it is within the appropriate range. 7. After replacement, test drive the car to verify the braking performance.

What to Do When BYD S6 Cannot Detect the Key?

BYD S6 cannot detect the key for the following reasons and solutions: 1. The one-button start cannot detect the key: The key may be out of battery or the battery contact is poor. Solution: Replace the battery. 2. Take out the spare key and test if it works: If it works, it means the remote key is faulty; if the spare key does not work, other reasons must be considered, such as electromagnetic interference nearby, signal interference sources, etc. Solution: If the key is faulty, go to a repair shop for maintenance; if it is electromagnetic interference, change the location and try again.

How to distinguish between genuine tires and retreaded tires?

The methods to distinguish between genuine tires and retreaded tires are as follows: 1. When replacing tires, carefully check the markings on the tire tread for Chinese color labels or black labels; verify if the tire name, specifications, load index, and speed rating on the Chinese label match those embossed on the tire sidewall; and check if there is a barcode on the tire bead. 2. Tires with artificially processed tread patterns are counterfeit. Genuine tires have very regular and clear tread patterns with deep grooves, giving a visually pleasing appearance. Counterfeit tires, due to significant damage to the tire body, require extensive modifications to the tread patterns. If the overall pattern appears irregular or deliberately altered to create visual interference, it is likely a counterfeit tire. When purchasing tires, carefully compare the tread patterns—disorganized patterns are a strong indicator of counterfeit tires. 3. Genuine tires have uniform tread thickness and consistent color. The tire body appears dull but has excellent elasticity and toughness. When touched, the tread feels soft with noticeable rubber particles and no pungent odor. Counterfeit tires are stiffer, with uneven tread thickness, and rough edges that are easily noticeable upon close inspection. 4. Retreaded tires usually have a layer of wax on the surface, making them appear unusually shiny. Pressing hard on the tread with a finger will leave a fingerprint, whereas new tires generally won’t show marks under similar pressure. Additionally, pull on the rubber studs and wear indicators on the "new" tire—genuine tires have better elasticity. Lightly scratch the tire surface with a key; genuine new tires usually won’t show scratches.
