Reasons why the Volkswagen Tiguan fan does not turn: Water temperature not reaching the required level: Most car radiator fans nowadays operate using electronic temperature control. Therefore, the fan usually starts turning normally only when the internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not turn. Hence, when the car radiator fan fails to turn, the first thing to check is whether the water temperature has reached the required level. Relay malfunction: If the water temperature meets the requirements but the car radiator fan still does not work, the issue might be with the fan relay. If the relay malfunctions, the car's radiator fan cannot operate. Thermostat switch problem: If there are no issues with the above two aspects, then the thermostat switch should be checked. Sometimes, faults can occur in this area, which can also affect the operation of the car radiator fan. Therefore, it is important to inspect this as well.

What to Do When Cruise Control Fails?

Here are the solutions when cruise control malfunctions: 1. Try to deactivate it. Press the 'cancel' button on the cruise control switch while simultaneously pressing the 'on' main switch, attempting to deactivate it by pressing both buttons together; 2. Shift to neutral. Cruise control is designed to cancel immediately under two conditions: braking or shifting to neutral. For automatic transmission vehicles, push the gear lever to the 'N' position; for manual transmission, simply shift to neutral. The car will lose forward momentum, and the speed will gradually decrease. Below are emergency measures if cruise control cannot be deactivated: 1. Deliberately scrape against guardrails. This method is highly difficult and dangerous, hence not recommended. 2. Intentionally rear-end a medium or large bus. The front vehicle will brake after the collision, causing the rear vehicle to stop. This method should only be used as a last resort. 3. If fuel is low, run it dry. This approach usually does not harm the vehicle and has the lowest post-incident repair costs, but it is essential to call the traffic police to open a green channel.

What is the engine RPM of the Volkswagen Sagitar at a speed of 120 km/h?

When the Volkswagen Sagitar 1.4 automatic transmission is driving at 120 km/h, the engine RPM is between 2500 and 2800. Normal engine RPM: Generally, for family cars, the engine RPM during driving is between 2500-3500, while the idle RPM is usually around 800-1500. If the engine RPM is too low, the fuel will not burn completely in the cylinders, leading to carbon buildup in the engine. Over time, this can cause more damage to the engine. Abnormal engine RPM situations: During a cold start, if the engine idle RPM is below 800 RPM or above 1500 RPM, it indicates poor engine performance.

What is the reason why the Mercedes-Benz R350 electric tailgate can only open but not close?

Mercedes-Benz R350 electric tailgate can only open but not close may be due to something blocking it; the hand button is not pressed properly or the locking motor has a problem. Solution: If you want the tailgate to close, the system must automatically relearn and reset. After starting the car, there is a button on the left door that can remotely control the tailgate. Press and hold the button to close the tailgate. Once closed, press the button again to allow the system to relearn and rememorize. In severe cases, the anti-pinch strip may need to be replaced to resolve the fault, and the trunk can then close normally. Precautions: When the car is in a no-power state and the tailgate is open, do not manually press the tailgate. Doing so may cause a system error and generate system garbled code.

How Many Liters of Engine Oil Should Be Added to a Volkswagen?

Volkswagen has many different types of vehicles, and the amount of engine oil to be added should be determined based on the actual situation. It is recommended to add the oil in multiple small increments to avoid overfilling, which could damage the engine. Examples: For the Volkswagen Tiguan, usually about 4L of engine oil is added; for the Volkswagen Tayron, approximately 5.5 liters of engine oil is typically added. The oil level should be between the minimum and maximum marks on the dipstick. Choosing Engine Oil for Volkswagen: Volkswagen vehicles should use engine oil products that meet the VW502.00 standard or higher, meaning the oil should have a dynamic viscosity greater than 12 at 100°C and a high-temperature high-shear viscosity greater than 3.5 at 150°C.
