Like the BMW can have a lot of reasons, performance and driving pleasure is always the soul of the BMW. As a high-end brand in the mainstay, BMW cars by many consumers trust, and BMW 5 Series is definitely the most advanced high-end business car. Such as the BMW 5 Series such a good car there will be a variety of annoying problems, some of the problems of the vehicle itself and some other problems. Is the owner of the car caused by the bad habits, the following we visited the BMW maintenance experts, listen to the BMW 5 Series owners in the use of the process will encounter what common problems and provide a solution for your reference.
    Configuration problem
    The BMW 5 Series is equipped with front-end airbags, front and rear head airbags, front side airbags, and side impact protection systems for the owner's equipment on the dynamic performance and safety performance of the vehicle. Entertainment and comfort are also no less, such as leather seats, advanced automatic air conditioning, BMW professional radio and CD players.
    BMW's car is known for its advanced computer system, and BMW's famous iDrive system is a must-see for BMW fans. The new BMW 5 Series is equipped with a new iDrive system. The second generation of BMWiDrive central information processing system can provide more powerful, more simple mode of operation. But the computer system failure is also BMW 5 Series owners more distressing problems, such as no reason to alarm, iDrive system suddenly failed, the lights automatically open and so on. In fact, this is due to problems with the car computer program, resulting in the root cause of the problem has not been found, which are part of the software failure, for the safe operation of the car and use is not much problem, if the occasional failure, then you can go to the trunk The battery line off the big line, so that the car computer can be resolved to restart. And if the problem frequently affect the normal use, then you can go to the aftermarket department of computer software upgrades, you can solve the problem.
    BMW 5 Department of the door is a terrible problem, the BMW company that is a plastic issue, it is not true. Even if the replacement of the tape can not solve the problem. In fact, the problem is out on the door hook, because the door hook lack of oil. If the owner wants to solve this problem, then only in the door hook evenly coated with oil, the problem can be completely resolved.
    There are owners of the BMW 525i, air conditioning system in the cooling switch is turned on, the fan 1, 2, 3 files are no wind blowing, but transferred to 4 when there is a small wind blowing, and then after a period of time and automatically jump The In fact, 4 small wind blowing, indicating the fan running, the cooling system is normal, but the regulation system is faulty. Demolition of the fan temperature control resistor (the resistance of the contact and the fan gear match), in the cold and hot state under the measurement, the resistance of the resistance did not change. When the resistance on the fan outlet before the fan up to 1 hour will automatically jump, this phenomenon is strange. After careful observation found that: resistance has a contact rivet loose. Riveting the rivets, the resistance back in place, and then open the fan test, the fan no longer jump, the stalls are back to normal.
    Driving problem
    BMW 5 Series has a BMW model with a unique dynamic and excellent handling performance, slender engine cover, short front suspension, 50:50 body weight, and high-end car's traditional rear-wheel drive way to make BMW5 series of classic difficult to be copy.
    Sometimes the BMW 5 Series owners will find the engine jitter, driving which will turn off. The reason is that most of the above problems are mostly due to the quality of the oil produced, a long time ago the owner hit the Mercedes-Benz event to determine the final cause of the car engine due to poor oil caused by adverse reactions. Such a luxury car like BMW, the engine design is very sophisticated, in order to ensure excellent performance, compression ratio is relatively high. But the quality of domestic oil and developed countries such as Europe and the United States there is a certain gap, fail to meet the normal requirements of the engine. So the high-end cars in the import of China have to carry out some targeted adjustments to enable it to adapt to China's oil, but the relative performance of the engine there will be some decline. But the domestic fuel quality is uneven, poor oil for the engine performance greatly affected.
    So the owner if you want to avoid this problem occurs, we must use the vehicle manual manual fuel specifications, to ensure the quality of the oil refueling, if forced to refuel in some remote areas, be sure to add the highest label gasoline, And in conditional time as soon as possible for qualified petrol. And if the owner of the region where the quality of oil is generally poor, must be used for a long time, it is best to go to the appropriate factory to adjust the ignition point of advance and make some changes to the computer program. So as to avoid irreparable damage to the engine.
    There are some BMW 5 Series owners will find the process of driving in the brakes or acceleration, the steering wheel will be slightly tightened to one side, when the release of the brake will be back again. This phenomenon is different from the tire pressure or tire problems arising from the deviation, because the suspension structure is fault. After observation, the chassis tripod rubber pad was disengaged. The most fundamental reason is that the chassis is not adjusted for the Chinese road conditions, part of the structure in the case of frequent bumps may be a problem. So the owner often need to check the various parts of the chassis suspension to prevent loosening phenomenon.
    Abnormal sound problem
    When the BMW 5 Series car driving a certain mileage will find the brake disc screams, in fact, the sound is from the brake disc and brake pads between the friction may be due to environmental problems, some dust can be mixed between the two , Resulting in contact is not real. In fact, this problem for the vehicle's braking or safety performance has no effect, if it can not stand, then the brake disc or brake pads can be polished to remove impurities and remain flat.
