8 years 110000 KM 530 station wagon, high-speed noise has been solved, the air suspension has also been replaced!
At the end of 2012, buy before your 40th birthday! Emperor Blue 530I.
In fact, the car usually does not use much, about a year 15000KM, which also includes two long-distance self-driving trips.
In the third year, more than 30,000 kilometers, the tires of the car were rough, and the original car was a horse plate, but later it was all changed to Pirelli. I heard that four-wheel positioning could not be done casually, so it was only a routine dynamic balance.
Drive more than 30, 000 KM, this Pirelli is more wear-resistant, but once went out on a self-driving trip to change a friend’s golf section on the highway, feeling that my car noise is much louder than golf, I began to doubt life!
Self-driving back to Guangzhou began to toss around, first went to a 4S store, did not arrange a test drive, did a routine test to say that the car is fine.
Later, when he went to a maintenance shop, he tried it around and said it might be caused by bearing wear, so he changed a pair of front bearings, but there was no significant improvement.
All kinds of information and possible similar cases have also been checked on the Internet. There are several possible wear and tear of transmission shafts, bearings, and tires.
Later I wondered if it was the transmission shaft.
Recently, when I was parked in a parking lot, a female driver bumped into my car and took it to a 4S store for repair. by the way, she found a tester to drive around and finally gave an answer: the tire problem caused high-speed noise.
Describe the noise characteristics: in the cement road noise is louder, the speed above 60 begins to appear, more than 80 is very obvious, whether to step on the throttle is the same, the noise is characterized by the rhythmic continuous sound of winter winter.
Then made a four-wheel positioning in the 4S, and then changed the Michelin silent tire, just changed a few days, I feel that the world is much quieter.
In conclusion, do not mess around, or to the 4S store to find a professional tester, and then should be excluded from the simplest tires!
I can’t see the abnormal wear of the tire. The tester can see it at a glance and tell me carefully. If there is an anomaly there, he can also help me analyze what the abnormal sound of the transmission shaft should be, what the abnormal noise of the bearing should be, and what the ball cage is like.
Must give the test driver of Baoyue Panyu store a like!
In addition, many people have a lot of problems with their BMWs. Let me talk about the problems with my car:
It is true that there are a lot of problems, but they are basically solved!
As soon as you eat the fetus, 3WKM will replace the original fetus.
Second, air suspension, the car after the empty suspension, the airbag can not be inflated, 4 years or so has been insured, 4S store customer service manager to help apply, free of half the maintenance fee, the actual total maintenance cost of 12800.
Third, the water tank is leaking, although it is overinsured at about 70, 000 KM, 4S helps to apply for free maintenance. Common faults can be operated in this way.
Fourth, engine oil leakage, this is about 40, 000 KM routine maintenance time, 4S shop made, the original factory claim for no money.
Fifth, other problems are aging, sticky and black on the handrail of the door handle in the car. This is inexplicable, and so is the 7-Series. Mercedes-Benz heard that it was the same. Fortunately, there is a substitute on the Internet, and the four handrails have been changed at a cost of several hundred yuan.
The above problems are all over, and now the car has become very understanding, the integration of people and cars!
Self-priming, straight six, Deyuan classics, worth collecting!

Use the car for nearly 8 years, and like self-driving, if the chassis is a little higher, even better!

At present, the car has changed hands.
