What is the reason why the BMW 3 Series air conditioner only blows air but does not cool?

BMW 3 Series air conditioner only blows air but does not cool for the following reasons: 1. Lack of refrigerant: Refrigerant wear is mainly due to leakage. If the condenser leaks, the condenser needs to be replaced. When the leakage is severe, oil stains can be seen on the surface of the condenser through the grille, which usually indicates a condenser leakage. 2. Damaged air conditioning flap: Damage to the air conditioning flap motor is relatively rare but not unheard of. The flap motor is usually located in the lower middle part of the instrument panel and serves as the main switch for the air conditioning vents. Once the flap is damaged, even if the air conditioner can cool, cold air can only escape through gaps. 3. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. In spring, willow catkins and poplar catkins sticking to the condenser can cause the engine temperature to rise or poor air conditioning performance. When cleaning, be sure to first use an air gun to blow away debris before washing with a water gun, otherwise it may have the opposite effect, leading not only to poor air conditioning but also increased fuel consumption. 4. Damaged air conditioning compressor, throttle valve, or expansion valve: High low pressure and low high pressure indicate the need to replace the compressor. Faults in the expansion valve and throttle valve directly lead to poor air conditioning performance. 5. Aged or loose belt: Generally, during maintenance, the 4S shop will remind you to replace the belt. If it is not replaced, slipping may occur during use, leading to belt breakage, belt noise, loss of power assistance, and poor air conditioning performance.

Is 100 km/h Considered Speeding?

100 km/h is equivalent to 100 kilometers per hour, which translates to 1667 meters per minute or 28 meters per second. This is already a very high speed. Below are the relevant speed limit regulations: 1. For roads without a central dividing line, the speed limit is 30 km/h in urban areas and 40 km/h on highways. 2. For roads with only one motor vehicle lane in the same direction, the speed limit is 50 km/h in urban areas and 70 km/h on highways. 3. When entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, or narrow bridges, making U-turns, turning, descending steep slopes, or encountering fog, rain, snow, dust, hail with visibility within 50 meters, driving on icy, snowy, or muddy roads, or towing a malfunctioning motor vehicle, the maximum speed must not exceed 30 km/h. For tractors, battery-powered vehicles, and wheeled special machinery vehicles, the speed must not exceed 15 km/h under these conditions.

Is Fuchs PT7 Engine Oil Fully Synthetic?

Fuchs PT7 engine oil is not fully synthetic. Below is relevant information about synthetic oil: 1. Introduction to synthetic oil: Synthetic oil is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which then undergoes complex chemical reactions (Fischer-Tropsch synthesis technology, i.e., GTL technology) to refine into large-molecule base oil. 2. Advantages of synthetic oil: Synthetic oil has a higher viscosity index, so it has better viscosity-temperature characteristics, providing more sufficient lubrication at high temperatures and better fluidity at low temperatures (appearing thinner than mineral oil of the same grade at room temperature). Engine oil blended with synthetic oil has stronger oxidation resistance, significantly extending the oil change interval. Although the investment in oil increases, the number of oil and filter changes is reduced.
