How can you tell if the door has been replaced in a used car?

First, the installation in the factory is not so precise, so it will be more difficult to open and close, and it may not be closed tightly. Second: Check whether the gaps on the left and right sides of the door are neat and symmetrical.

Observe from the gap of the B-pillar door to see if it is a straight line, if the gap is large, it means that the door may be overhauled. Secondly, check whether the interface between the door and the car body is neat and whether the bolts are falling off. If the joints are not neat, the bolts are loose or fall off, the door may have been replaced.

Finally, check whether the adhesive on the underside of the door is still present and whether the adhesive on the inside edge of the door is aged and deformed to determine if it is a second-hand door.

Third: remove the sealing strip on the door, carefully observe whether the door frame is parallel to the door post, and whether the position of the solder joint is round and slightly convexIf yes, it means the original door; If the solder joint is rough and uneven, it can be judged that the car may be an accident car and the door has been repaired. Fourth:

Check the maintenance records of the 4S shop. If the door is replaced, the repair record of the 4S shop and the insurance company will have a record, but if it is repaired at a small repair shop, there may not be a relevant record.

The car door is to provide the driver and passengers with access to the vehicle, and isolate the interference from outside the vehicle, to a certain extent, to reduce the side impact and protect the occupants. The beauty of the car is also related to the shape of the doors. The quality of the door is mainly reflected in the anti-collision performance of the door, the sealing performance of the door, etc.

Summary; As for the doors as a whole, especially the left front driver door, the internal electrical system is very complex and important. If it is replaced with a new one, the connection between the circuit system and the body will not be exactly the same. Moreover, the original circuit system is well matched with the vehicle, and the replacement is very easy to cause circuit failure, which may cause fire.

Therefore, we should choose the original door and try to avoid the root cause of the second-hand door after the accident.

Tear off the sealing strip on the door, carefully observe whether the door frame is parallel to the door post, and whether the position of the solder joint is rounded and slightly convex, if so, it means that it is the original door; If the solder joints are rough and unevenly arranged, it can be judged that the car may have been an accident and the doors have been overhauled.

Feel the doors open and close. The original door must be very smooth to open and close, and the replaced door is not so precise in the factory, the opening and closing will be more laborious, serious may not be able to close tightly.

If it takes a lot of effort to open the door, or if the door opens easily. It shows that there is a high probability that the door has been replaced.

Check whether the connection of the door is smooth and whether the door is good or not.

We can see the degree of wear and tear at the connection, and we can also see if there is any abnormal noise when closing

There are machines that are specially inspected, and it can also be judged based on experience.

This only needs to be based on the factory date of the door, and then sent to the corresponding manufacturer for inspection.

Try it yourself to open and close the doors smoothly and you'll know as soon as you try it.

You can try it yourself, but of course it's best to find a professional to check it out.

I think you should ask the user of the car in detail before buying.

For second-hand cars, replacing the door means that the second-hand car has also experienced a lot of accidents, and it also has a certain impact on the second-hand car, but if you simply replace the door, the impact on the price of the second-hand car is relatively small.

The sheet metal spray paint that was removed from it didn't have much effect.

If the bottom side is not very seriously deformed, it can be repaired by sheet metal according to the normal situation, and the bottom side only needs to be re-sprayed after the repair, so you don't have to worry about the beauty or safety of the vehicle being affected; If the deformation of the large side of the bottom is more severe, some Bi or stool repair shops will propose to cut off the deformed part and then weld a good replacement, but this practice will generally be classified as an accident car.

Does the original car door have plastic strips?

In the case of the original door, there is no plastic strip.

I changed the left side door, and today I found out that there is hemming glue on the side of the original car. And the left side door is not edging glue, is it an auxiliary door?

It must be the original door, and the original one doesn't have it.

Today, I found a third-party appraisal again, saying that it was a vice factory, and I don't know who to believe? The owner of the second-hand car dealership also looked at it and also believed that it was an analogue part, and if the analogue door and the original car door were made, it could be seen from the exterior of the sock paint and the external device. In the case of the doors of the original factory, there are corresponding rubber strips on the side of the door, and the doors ordered from the original factory in the later period are not available.

If there is no sheet metal glue. That's what the factory is. If there is sheet metal glue, it is the sub-factory.

And this kind of statement?

You can buy any side factory door from the market, and it will be made of sheet metal glue, which is the difference between the original factory and the side factory. You can consult from the market. Or find someone who specializes in selling BMW accessories and ask him to take a picture of the door for you, which must be 100% covered with sheet metal glue.

You can see it.

It is divided into the following aspects.

1.It is to see the signs of loose screws.

2.Replacing the door is to replace only the door and not the other parts inside.

When the door of the shop came, there was no paint and it needed to be repainted.

4.Some accessories outside the car can also be seen.

Yes, because the parts involved when you disassemble the door will definitely have traces of disassembly, even if the exterior is good, the inside cannot be changed.
