For normal household cars, it is not recommended to flash the ECU. Reasons for not recommending: The car's powertrain is matched with the chassis, suspension, brakes, and shock absorbers. If only the power is increased without upgrading other configurations, the car will inevitably develop issues and pose safety hazards. Introduction to ECU: ECU stands for Electronic Control Unit, also known as the onboard computer or vehicle computer. It consists of large-scale integrated circuits such as microcontrollers, memory, input/output interfaces, analog-to-digital converters, and drivers. How the ECU works: After igniting and starting the engine, the ECU begins operation. The central controller retrieves fixed programs from the memory and processes and executes the programs in sequence based on signals sent by various sensors, such as controlling the air-fuel ratio, ignition timing, idle conditions, etc.

What is the reason why the rear glass of the Passat cannot be fully lowered?

Here are the reasons why the rear window of the Passat cannot be fully lowered: 1. The rear window of the Passat cannot be fully lowered, leaving about one-third of the glass exposed above. This is due to design and safety considerations. The area below the rear door is often near the wheel, and the lower door frame is inclined or curved, resulting in an irregular shape. This reduces the available space below the rear door compared to the front door, preventing the window from being fully lowered. 2. For some models, the wheel arch design causes a noticeable narrowing in the lower part of the rear door panel. When the rear window is lowered, the lower part of the door panel does not have enough space to accommodate the glass, resulting in the window not being able to fully lower.

What does the AC in a car's air conditioning mean?

AC in a car's air conditioning system refers to the air conditioning cooling switch, which is the power switch for the air conditioning compressor. When the AC button is pressed, the car's air conditioning compressor starts working, and the air blown out by the blower becomes cold. After pressing the AC button, the electromagnetic clutch of the air conditioning compressor engages, causing the compressor to operate, and the car's air conditioning enters the cooling mode. Additional information about automatic air conditioning is as follows: 1. Automatic air conditioning automatically adjusts the interior temperature based on the temperature difference between the inside and outside of the car. 2. When using the air conditioning for heating in winter, the AC light being on does not assist in heating; instead, it causes unnecessary power loss due to the compressor's operation.

Does Auto Start-Stop Require Continuous Brake Pedal Pressure?

Auto Start-Stop requires continuous brake pedal pressure. Below is a detailed introduction to Auto Start-Stop: 1. Engine Auto Start-Stop automatically shuts off the engine when the vehicle temporarily stops during driving (e.g., at a red light). When it's time to move forward again, the system automatically restarts the engine. 2. The working principle of the Engine Auto Start-Stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there's sufficient energy for the next start.

How many kilometers should transmission fluid be changed?

Transmission fluid should be changed every 40,000 kilometers. If the transmission fluid is not replaced for a long time, it can easily become thicker, leading to reduced oil pressure and obstructed internal heat dissipation, which will cause the oil temperature to rise too high. Once the lubrication effect deteriorates, it will lead to rapid wear of components, damaging the internal parts of the transmission and shortening the lifespan of both the transmission and the drivetrain. Transmission fluid is an oil product that keeps the gear system clean, providing lubrication to extend the life of the drivetrain. It offers effective lubrication even at low temperatures and reduces oil loss under harsh operating conditions. Depending on the transmission structure, transmission fluids are categorized into automatic transmission fluid and manual transmission fluid.
