The annual "March 15" International Consumer Rights Day is approaching, and the topic of product quality and safety has once again received widespread attention. According to the complaint data of Automen.com, many cars have encountered concentrated complaints in the past year, and the quality and service problems of these automotive products have exhausted car owners. Boarding the "3 15" has become an important solution for car owners to solve problems. Therefore, which auto product will be listed on "3·15" has become the most concerned topic for consumers. On the eve of "March 15", we will take stock of the problem models. Today, we talk about the problematic BMW X1.
Although it has always been the sales leader of luxury compact SUVs, the quality of BMW X1 products is not reassuring. In the past 2021, the BMW X1 has received two centralized complaints.
The first time appeared in March last year.
Autogate's complaint index shows that bmw X1's march complaint index surged nearly three times from February. Judging from the feedback of car owners, the problem of engine idling has become the culprit that has pushed up the BMW X1 complaint index. According to statistics, the complaint rate of BMW X1 engine idling increase accounts for more than 60%.
According to a BMW X1 owner, the cold car is normal, as long as the outside temperature is high or the engine is running under heavy load, the engine idle speed will automatically increase to 1000 rpm and cannot be lowered. When the idle speed increases, the timing of the gear change will also be delayed to 2200-2500 rpm, and the brakes will become stiff. When the brakes are released, there is a feeling that someone behind is pushing the car away.
He also said that the 20 previous models did not have the problem of high idle speed, and since the 20 models were equipped with B48TU engines, the 2.0T X1 has an increase in idle speed.
Auto door network found that all major network platforms have BMW X1 owners feedback on the problem of engine idle speed. Judging from the feedback, the problem has been going on for more than half a year. It eventually erupted in March.
After combing, it was found that the problem appeared concentrated in the 2020 and 2021 models of the 2.0T country VI. model. Car owners generally reflect that after the vehicle is driven at high speed or for a long time, the engine idle speed will increase to 1000 rpm or even 1500 rpm, and the timing of gear change will also be delayed to about 2200-2500 rpm, the brake will also become hard, and there is a phenomenon of intrusion after releasing the brake.
Surprisingly, the owners have changed the spark plug, the oil grid, the replacement of the carbon can solenoid valve, the air flow meter, the intake pressure sensor, the throttle pressure difference sensor, and the engine computer board, but the idle speed increase problem will still appear. According to the feedback of the owner, although the 4S shop knows that there is a problem with the vehicle, it cannot find the reason.
Subsequently, some users speculated that the occurrence of this problem may be related to GPF (particle trap) regeneration. This judgment was also confirmed by BMW's German technicians. According to the information revealed in the BMW X1 owner group, the problem of BMW X1 idle speed increase has been reported to BMW's Headquarters in Germany. The German side said that the BMW X1 idle speed increase was caused by particle trap problems. But no official message flowed out.
BMW's Headquarters in Germany said the increase in IDLE speed of the BMW X1 was caused by a particle trap problem. But no official solution has yet been introduced.
Just two months later, the BMW X1 had problems again.
Autogate's June complaint index showed that the BMW X1's complaint index reached 84.15, more than doubling from the previous month. This time, the engine noise of the BMW X1 was met with concentrated complaints from many car owners.
According to the owner, when the throttle is normally driven, the engine will make a noise noise, and the sound will disappear after closing the throttle. After going to the 4S shop for testing, the staff said that the sound was a turbine sound, which was a normal phenomenon.
The survey found that the engine noise problem appeared in the 2020 models, and there were a large number of cases in the 20Li and 25Li versions. Car owners generally reflect that after the new car travels thousands of kilometers, the problem of abnormal noise will appear. Many car owners have been told that the problem is normal.
Combined with the feedback of the owner, the abnormal sound is emitted by the position of the lever of the bypass valve of the turbocharger. A car owner who experienced the problem said that the 4S store sent the relevant inspection data to the BMW head office, and finally determined that there was a problem with the turbocharger and needed to replace the turbocharger assembly.
However, another owner left a message saying that the turbocharger was replaced in the second half of 2020, but at the end of February this year, the engine noise appeared again. He pointed out that because the BMW X1 in this batch is equipped with a turbine bypass valve pull rod that is too large, when the turbine is started, the tie rod position will emit a strange sound.
One owner said that other brands of turbocharged models have similar problems, but have been solved by adding cards. The owner's statement was confirmed by the staff of the BMW 4S store: only the card can solve the problem, and it is useless to change the turbine.
The problem is that other brands have launched related spare parts, but BMW has not launched a turbocharger card for BMW. Therefore, the issue has not been resolved.
In recent years, BMW's sales in the Chinese market have risen, and product quality problems have also increased. According to the data of the car door network, in the past two years, the BMW 3 Series burned oil, leaked antifreeze, brake pad wear, BMW X1 idle speed increase, turbocharger abnormal sound, BMW iX3 power battery failure and other problems have been plaguing car owners, but BMW has rarely responded and effective solutions.
We hope that BMW can actively solve the problem and give many car owners who trust BMW a peace of mind.
