What are the reasons for BMW's high fuel consumption?

BMW's high fuel consumption can be attributed to various issues. The specific reasons are as follows: 1. Fuel system problems: It could be due to issues in the fuel system. After a car has been driven for several years, carbon deposits may form on the fuel injectors, leading to clogging. In severe cases, this can cause fuel leaks in the fuel lines, clogged fuel filters, and other issues. These problems reduce the amount of fuel entering the combustion chamber and impair atomization, resulting in decreased combustion efficiency. This leads to reduced power output and sluggish performance. 2. Air intake system problems: Inadequate vehicle maintenance, such as failing to clean the air filter, can cause blockages. If the throttle body becomes clogged, it reduces the air intake, leading to incomplete combustion. 3. Engine misfire: In fact, engine misfire can also cause the aforementioned issues and is often accompanied by severe idle vibration, necessitating a comprehensive vehicle inspection.

What is the reason for the fault code U007300 in the Baojun 730?

TCM power or ground is suddenly interrupted during driving, causing the entire TCM control module to stop working. Vehicle fault self-inspection terminal: The vehicle fault self-inspection terminal can diagnose the status of sensors and actuators in the electronic control system and whether the ECU is functioning normally. If abnormal, it will transmit a fault code. When a circuit in the electronic control system generates a signal that exceeds the specified range, the fault information related to that circuit and its sensors will be stored as a fault code in the ECU's internal memory. Maintenance personnel can use the diagnostic tool to read the fault code and display it. Reasons for the fault: TCM power or ground is suddenly interrupted during driving, causing the entire TCM control module to stop working. The CAN communication enable line of the TCM control module may suddenly disconnect or experience low voltage during driving, leading to CANBUS communication interruption in the TCM control module, or there may be an internal fault in the TCM control module.

Does a BMW Battery Need to Be Matched?

BMW battery needs to be matched. Matching method: There is a QR code label on the original battery. During matching, input the first row below the QR code. If a non-original battery is used, simply input a separate code. Points to note when replacing the battery: First, the battery capacity must be selected correctly. 90Ah refers to the battery capacity, while 900A represents the maximum starting current. Additionally, when replacing a BMW battery, it is recommended to use the original BMW AGM battery and then perform the matching, as this is the manufacturer's standard maintenance procedure. Under special conditions, non-original batteries can also be used. However, whether it's an original or non-original battery, if there is an alarm prompt on the dashboard, matching must be performed after replacement, and the battery code is required during the matching process.

What does the scan button on a car mean?

The electronic screen in the car displays SCAN, which means scanning, i.e., searching for radio stations and then stopping to listen to the current station. Here are the specific details: 1. The original meaning of SCAN is 'to examine carefully, to scrutinize,' etc. In the car, it represents scanning and searching for radio stations, meaning it searches for stations and then stops. 2. SCAN: When pressed in CD playback mode, the display shows the word SCAN, and the music will start from the next track of the currently playing music, scanning through each track for a few seconds before moving to the next track in a loop. When the user hears a track they like, pressing this button again will make the player start playing from that track. In other words, pressing SCAN makes the car scan and search for all receivable radio broadcasts. The radio will switch to a station, stop there for a few seconds, and then jump to the next station. Pressing the SCAN (search) arrow will stop the search and allow you to listen to the current station.

What is the original spark plug model for the Golf 7?

Golf 7 generally uses three types of original spark plugs: NGK94968 double platinum, NGK9563 iridium platinum, and NGK96596 nickel alloy. Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. Steps to replace spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage ignition wires according to the firing order, and then secure the cover.

Will the Golf 7 sunroof leak water to the rear footwell?

Golf 7 sunroof leakage will not reach the rear footwell. There are several reasons for roof leakage: 1. Sunroof leakage: Generally, there are two situations for sunroof leakage. One is that small sand particles or dust in the sunroof drainage channel cause blockage; the other is that the sunroof sealing strip has been "lifted" or displaced. Therefore, it is advisable to regularly clean the sunroof to maintain the cleanliness around the drainage channel. Also, don't forget to use high-pressure air jet equipment aimed at the drainage pipe during regular car washes to blow away any dirt inside the pipe. 2. Blocked drainage pipe causing interior leakage: The most common cause of interior leakage is the blockage of the drainage pipe under the front windshield. Infrequent car washing or long-term parking under trees can lead to dust, leaves, mud, and other debris being washed into the drainage pipe by rainwater. Over time, this can block the pipe, causing poor drainage. During heavy rain, water will naturally backflow into the car, resulting in leakage.
