3 Series abnormal noise at night and replacement of the engine bracket is a perfect solution

10 It used to start and stop, and nothing unusual was found. In recent months, the starting and stopping have been turned off. While waiting for the traffic lights, I suddenly heard the sound of a tractor. I looked around and saw no other vehicles! I didn’t care much at first, but later I realized that every time I put forward the parking lights and other traffic lights would appear! Moreover, only the forward gear will appear, and there is no abnormality in parking in other gears! I went to the 4s shop for inspections four times and tested with many shop masters for a few days. At first, the diagnosis was a gearbox problem. After the car was lost in the store for two days and the gearbox data was scanned, it still failed to solve the problem after a day of testing in the store! After a week, I continued to test with the master to find out the cause of the abnormal sound. After joint diagnosis by the technical manager and the team leader, it was said that it was an engine bracket problem and decided to replace the engine bracket. Since the engine bracket was not wearing parts, there was no stock in the store, so I needed to order it. The waiting period was one week. Just like this, I drove the tractor for another week, and the abnormal noise became more and more obvious! It seems that the Bavarian tractor lives up to its name!
Yesterday, I received a call from the after-sales consultant saying that the engine bracket had arrived and made an appointment to replace it this morning!
The one-sided bracket costs more than 1,000, and the working hours are also more than 1,000. Fortunately, the car has not expired its warranty period. It is free this time. I hope the problem can be solved!
There are a lot of bus queues on weekends, so I am bored waiting ~
Half an hour later, it finally came on sale
Engine guard must be removed
The cabin is completely exposed from bottom to top and is already clear
The silver one below is the bracket that needs to be replaced
Remove screws
This jack is a bit big
It must be lifted so that the bracket is free from force before it can be taken out
Left engine support removed
I bowed twice and it sounded a bit like a sound ~
Prepare to replace it with a new one
The master said this thing is a little difficult to install
New brackets are in place
After replacing and testing, there was no abnormality for the time being ~
The test is over! Start system testing and then wash the car ~ Light meal at noon in the store!
After 1 o’clock in the afternoon, the car wash was completed, and the formalities were completed. Let’s go home!
I hope the problem is solved and there will be no abnormal noises again!
