Will the points deducted through legal learning be added to the original points?

The points deducted through legal learning will not be added to the original points. Instead, drivers can have their traffic violation points reduced by receiving education. Within one scoring cycle, a maximum of 6 points can be deducted. There are three ways to deduct points through legal learning: 1) Participating in online learning (accumulating 30 minutes within 3 days) and passing the exam can reduce 1 point; 2) Participating in on-site learning (no less than 1 hour each time) and passing the exam can reduce 2 points; 3) Participating in traffic safety public welfare activities (1 hour each time) can reduce 1 point. There are 7 situations where the 'legal learning point deduction' cannot be applied: 1) During the current scoring cycle, the driver has more than two full-point records or the accumulated points reach 12; 2) In the previous scoring cycle, the driver had more than two full-point records; 3) In the last three scoring cycles, the driver was penalized for hit-and-run accidents, drunk driving, using forged or altered vehicle license plates, driving licenses, school bus signs, or other vehicle documents, or buying/selling points; 4) The driver's license is in the probation period, overdue for review, or suspended; 5) The driver has unprocessed traffic violation records; 6) The driver owns a vehicle with an expired safety inspection or has not followed the deregistration procedure; 7) The driver engaged in fraud or impersonation during the traffic safety education or point deduction process.

What Causes Oil Leakage from the Passat Engine Cylinder Head?

There are several reasons for oil leakage from the Passat engine cylinder head: Oil seal leakage or gasket failure: For issues like oil seal leakage or gasket failure, you can disassemble and replace them, or apply heat-resistant sealant. Currently, there's also a small trick—adding a solute claimed to enhance rubber plasticizer into the engine oil. After normal driving for a period, the oil leakage condition may improve. Excessive engine RPM: Matching vehicle speed with RPM helps reduce engine oil leakage. It's best to keep the engine RPM below 2500rpm. Shifting gears when the RPM exceeds 2000 can not only prevent oil leakage but also reduce engine wear.

What type of engine oil should be used for the Emgrand EC7?

Engine oil can use Aojixing SL5w-40, which has the right viscosity. User Manual: The Emgrand EC7 user manual specifies the use of SJ grade or higher engine oil. You can purchase SJ/SL/SM grade oils. In summer, use 5w-40 viscosity, and in winter, 5w-30 can be used. Gasoline engine oil cannot be used for diesel engines: Do not use specialized gasoline engine oil as a substitute for diesel engine oil to avoid accelerating wear on the diesel engine. Gasoline engine oil and diesel engine oil should, in principle, be used separately. Only when the car manufacturer provides substitution instructions or the oil is labeled as suitable for both gasoline and diesel engines can it be substituted or used within the specified grade range. Engine oil viscosity should be as low as possible: Under the premise of ensuring reliable lubrication for the engine, the viscosity of the engine oil should be as low as possible. High-viscosity oils are only suitable for severely worn engines or for use in southern summers. Choosing excessively high-viscosity oil will increase the engine's operating resistance, leading to higher fuel consumption. On the other hand, selecting oil with too low viscosity may result in insufficient oil pressure, inadequate lubrication film strength, and poor sealing.

Where is the intake air temperature sensor located on the Volkswagen Touran?

Intake air temperature sensor is located on the intake hose after the air filter or on the mass air flow sensor. Working principle of intake air temperature sensor: The intake air temperature sensor is a negative temperature coefficient thermistor. When the temperature rises, the resistance decreases, and when the temperature drops, the resistance increases. As the resistance in the circuit changes, it causes voltage variations, thereby generating different voltage signals to complete the automatic operation of the control system. When the engine is cold, the signal from the intake air temperature sensor is basically the same as that from the engine coolant temperature sensor. When the engine is warm, its signal voltage is approximately 2 to 3 times that of the coolant temperature sensor. Function of intake air temperature sensor: To detect the intake air temperature of the engine and convert it into a voltage signal input to the ECU as a signal for fuel injection correction.
