The alarm sounding a few hours after locking the car is due to the vehicle alarm system failing to detect the front sensor or the front sensor sending an alarm signal, which triggers the alarm. The solution is to inspect the sensor causing the alarm and check the vehicle's wiring. Here is an introduction to car alarms: Function: A car alarm is an alarm device installed in a vehicle. If someone hits, impacts, or moves the car, the sensor sends a signal to the controller, indicating the intensity of the vibration. Depending on the vibration intensity, the controller emits a warning sound or fully activates the alarm. This serves to deter thieves and alert the owner. Development: From the 1990s to the present, car alarms have developed rapidly and are increasingly widely used. As car alarm technology has become more mature, cost control is no longer a challenge, and car alarms have become essential equipment for every car owner. In the next decade, it is believed that car alarm systems will incorporate more advanced technologies. In-vehicle GPS receivers have opened up vast possibilities in the security field. If the receiver is connected to the alarm system controller, it can report the vehicle's location to the owner or the police at any time.

Where is the N13 charcoal canister solenoid valve located on a BMW?

BMW N13 charcoal canister is normally installed above the right rear or left rear floor panel, and the solenoid valve is generally located near the throttle body, serving as a three-way valve. Introduction to the charcoal canister solenoid valve: The charcoal canister solenoid valve is a device installed in vehicles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. When the vehicle starts, the solenoid valve opens, releasing the adsorbed fuel vapor into the intake manifold for combustion in the engine. Working principle of the charcoal canister solenoid valve: Due to the sealed nature of the fuel tank, fuel consumption creates negative pressure inside the tank. Under this negative pressure, gasoline vaporizes more easily than under normal atmospheric pressure. When the engine is off, the charcoal canister stores the mixture of fuel vapor and air emitted from the tank in the micropores of its activated charcoal, preventing the vapor from escaping into the atmosphere.

What is the standard tire pressure for Mercedes-Benz E run-flat tires?

Mercedes-Benz E-Class has different normal tire pressures for different tires. For R16 and R17 tires, the normal tire pressure when half-loaded is 260 kPa for both front and rear tires. When fully loaded, the normal tire pressure for the front tires is 260 kPa, and for the rear tires, it is 330 kPa. Recommended tire pressure: The recommended tire pressure for Mercedes-Benz E-Class run-flat tires is 30 kPa higher than the normal tire pressure. Introduction to run-flat tire pressure: Run-flat tire pressure refers to the pressure in tires equipped with run-flat technology, which allows the vehicle to continue driving safely even when the tire is punctured, enabling the driver to reach a repair shop. Mercedes-Benz vehicles generally use run-flat tires, but drivers should not rely solely on them and should repair the tires promptly. Additionally, for safety reasons, it is best not to exceed the recommended run-flat tire pressure value but also not to let it drop below 210 kPa.
