Volkswagen Group 91 and 93 data streams are preset values when the vehicle leaves the factory. High or low data values indicate abnormal data streams. Abnormalities in Group 91 and 93 data streams occur because the EA888 engine experiences abnormal vibrations during startup. Continuing to start the car under these conditions can cause the timing chain to skip teeth, leading to valve collision with the cylinder. It is recommended that owners take their vehicles to a 4S shop for inspection and repair. Below is a detailed introduction about automobile engines: Overview: Depending on the power source, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power, among others. Others: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which can convert the chemical energy of fuel into the mechanical energy of piston motion and output power externally.

What to Do When the Starter Doesn't Work?

The main reasons for the starter not working are: insufficient battery charge, and excessive resistance caused by poor wiring or connections, leading to reduced current. Here are the diagnostic methods for a non-working starter: 1. Use a conductor to bridge the two terminals on the starter switch. If the starter speed increases significantly, it indicates poor contact at the starter switch contacts, increasing resistance. If the starter speed does not change, check if the battery is sufficiently charged, if the brushes are excessively worn, or if the brush spring is too weak. 2. Local short circuits in the starter's armature coil or field coil can also cause the starter to lose power. Carefully inspect the starter circuit wires and connections. Poor wiring and loose, corroded connections will heat up due to increased resistance. 3. Mechanical faults inside the starter can also affect its normal operation. If the power supply, starter circuit, and starter switch are all intact, check for issues like friction between the armature and magnetic poles. 4. Under low-temperature conditions, the internal resistance of the battery increases, the terminal voltage drops, and engine resistance rises, which can also lead to symptoms of a weak starter.

Why is the tire pressure requirement for the Vezel so low?

Tire pressure should not be lower than the recommended value for half load, and not higher than the recommended value for full load. Within this range, adjustments can be made according to daily load, road conditions, and requirements for comfort, fuel consumption, etc. The tire pressure should be set according to the manufacturer's recommended value: The manufacturer's recommended tire pressure can usually be found in the vehicle's user manual, on the label next to the driver's door, in the drawer next to the driver's seat, or on the fuel tank cap. The manufacturer's recommended tire pressure refers to the cold tire pressure: Measured after the vehicle has been parked for at least 3 hours or if the tires have not been driven more than 2 kilometers. If tire pressure must be measured when the tires are hot, subtract approximately 0.3 bar (=4psi) from the measured value to obtain the cold inflation pressure.

Does the Dash Cam Automatically Record While Driving?

The dash cam automatically starts recording every time the car is turned on. Depending on the model of the dash cam, there may be different scenarios, as detailed below: 1. For single-camera dash cams, which are typically powered by the car's cigarette lighter or other in-car power sources, there are two types: (1) Models with motion detection. These dash cams usually have a small built-in battery. After the car is turned off, they will automatically start recording if there is movement in front of the lens. The built-in battery is generally sufficient for one night in a relatively quiet parking lot, but it won’t last longer or work well in busier areas. (2) Models without motion detection. These dash cams shut down when the car is turned off and are essentially useless when parked. 2. Dual-camera dash cams, which have one camera at the front and one at the rear of the vehicle, are usually hardwired directly to the car battery via the fuse box. These dash cams continue to work at night because they draw power from the battery, making them suitable for outdoor or remote parking. The downside is that they drain the battery.

Which Type of Engine Oil is Suitable for Turbocharged Engines?

For turbocharged models, it is recommended to use fully synthetic engine oil. Additional Information: 1. The construction of turbocharged engines imposes higher demands on the engine, as their internal components must withstand high temperatures and more severe impacts, compression, and other working conditions. Therefore, when selecting engine oil for turbocharged cars, it must have good anti-wear properties and also be resistant to high temperatures. Fully synthetic or semi-synthetic engine oils can precisely meet these requirements. Besides using the manufacturer-recommended oil, fully synthetic and semi-synthetic oils are both excellent choices. 2. The turbocharger is one of the most vulnerable components in a turbocharged engine. According to relevant data, more than 80% of turbocharger failures are due to insufficient lubrication from the engine oil. Hence, fully synthetic engine oil is currently the most suitable choice for turbocharged engines.

Is It Necessary to Purchase a Paint Protection Film?

Purchasing a paint protection film mainly depends on the owner's needs. If you plan to discard the car after three to five years, there is no need to buy it. However, if you aim to preserve the car's value or use it for several more years, then purchasing a paint protection film is advisable. The advantages of a paint protection film include: 1. Enhancing paint gloss. A paint protection film can improve the gloss and brightness of the car's paint, with varying effects depending on the brand, typically increasing brightness by 5%-30%. 2. Preventing physical scratches. The primary purpose of a paint protection film is to protect the car's original paint, especially against physical scratches. Minor scratches and abrasions can self-heal. It effectively prevents damage from road debris like stones and branches. 3. Preventing chemical corrosion. You won't have to worry about acid rain corrosion, oxidation, or damage from common road contaminants like bird droppings and insect remains. 4. Long-term value preservation. The transparent paint protection film perfectly safeguards the original paint while enhancing its brightness, adding aesthetic value. A well-maintained, brighter paint job can increase the car's resale value by 10%-20% in the used car market.
