Pure technical post, not rights protection post, the owner of the version, don’t look at the title and shoot me directly! !

Foreword:

In fact, I heard a long time ago that these two things were easy to go wrong, but later I was confident that my buddies were born lucky and hard to give up (mainly after buying a 3-year extended warranty, and there was still a 3-year warranty period), ha, so I forgot to go to Nanshan. Until recently, a buddy in my Chengdu five-series group just got out of bailout and said this in the group, and then the group exploded and went to see his car. 10 8 crack, the remaining 2 are waiting to crack, and 4S gives the maintenance quotation, accessories more than 3000, man-hour 50 hours, man-hour cost more than 3000, the total together more than 6000, some places quote more than 8000, I strangled to go, this matter is over. Then I raised the skylight carefully with the egg, the heartbeat 180 turned on the flashlight, trembled and took a closer look, leaning on, splitting one, ten thousand alpacas galloping.

First, the location of the fracture and how to check whether it is broken (there is a picture below)

Location: after the skylight is turned up, note: not after opening, but the two clasps after the front skylight is tilted.
Method: press the skylight button back to open the curtain, then press forward to tilt the back of the skylight, look with a flash on the car frame, or kneel on the seat to see whether it is broken.

Second, according to the collective feedback of my Chengdu five-series car group, several contents that need to be paid attention to.

1. Only models with domestic panoramic skylights have this problem. Single skylights with standard axes and domestic 525 single skylights do not have this problem, and then include M5, because it is not this accessory at all.
2. According to my careful observation, the cracked hard plastic clasp is used to raise the skylight at the rail connection or to open a skylight, and the hard plastic link to the iron is still the focal point, so it must be cracked and there is no way to run.
3. Definitely not because the skylight opened too much, so it cracked. I don’t smoke. I open the skylight no more than 10 times a year. I wash the car to clean the mud on the edge of the tape. Some of the people in the group have just carried the car for a month. Those who have driven the skylight twice have also cracked, so don’t take any chances.
4. Don’t think about gluing yourself with 520. One tease in the group says that you want to use 502 to stick yourself. Boy, there are slide rails inside the buckle. If you stick, you will really stick.

III. Maintenance procedures

Several friends of my Chengdu five series group are still in the guarantee to greet the 4S (the insured is numb, ). The maintenance procedure is the same: remove the interior decoration, remove the roof, and then replace the entire skylight bracket. In some places, it is guaranteed for 2 years, and if it is cracked and dismantled within two years, it will continue to be replaced. But there is a good chance that it will crack, because the quality of the parts has not been replaced, and it is only a matter of time before the parts are cracked. And 4S would like you to change, because he can eat the manufacturer’s maintenance fee. Next, I took apart the picture of the interior of the roof, which really hit my brains.

IV. Maintenance suggestions

In my long talk with the 4S technician, soft and hard, reasonable and emotional, hey, the master said, it must still be cracked, and this buckle is iron inside, which is essentially iron to iron. this hard plastic buckle is just a thing wrapped on the outside, and the possibility of opening a strange sound is weighed by yourself. therefore, the advice given by the master is that before the buckle is scattered and feels very firm, there is no need to change it. Of course, at this time, some smart friends must ask, if I don’t change, will there be any questions? it’s a really good question. Er, I also asked, the master said that there would be no skylight collapse, cracks and leaks, or anything like that, because it was covered on the edge of the skylight, not resisted. So my suggestion is that I won’t change the card buckle until it falls apart. Anyway, I still have 3 years to extend the insurance. I’ll see it before I get out of insurance, ha.

Summary:

Brilliance skull has shit ah, there is thin shit ah, with Mini iron sheet I recognize ah, even if it does not affect the use, but affect the look and feel ah, oops. But since it does not affect the use, my personal suggestion is that the card buckle will not fall apart, I will not take it apart or replace it, and you can feel free to have obsessive-compulsive disorder.

Picture and text explanation (pay attention to the text, especially the last few pictures)

Let’s start with a set of combined punches to scare you, all from my friends, ha, ha (this is the inside of the clasp I cracked, it’s still very smooth)
